Until you understand XAML, you should not be working with WPF. The point of WPF is the XAML. This is a declarative language. If you do not want to deal with XAML go to WinForms
Clifford Nelson 26-Sep-18 1:37am View
You should include your XAML.
Clifford Nelson 17-Jul-18 19:58pm View
Well that is true. If it is possible then you would need to add a check. You could make it a condition, and then should have a Debug.Assert. :-}
Clifford Nelson 1-Jul-18 2:51am View
I am no expert in C, but it appears you need to read a string:
gets( str );
and to get the length
strlen(str );
As I said I am no expert in C

Thanks so much for this. I had figured it out already.
Clifford Nelson 26-Jun-18 11:21am View
Might be a good idea to look at your keys and make sure those keys needed for the query have indexes. Also might figure out how to avoid all those converts, they cannot be helping

Glad it worked.

Try the code above. It removes the null which should not be there.

The reason you get a null exception error is because you did a bad think in your sample:
Cars= null
Try looking at One of his suggestions is avoiding null. Did you put null in there just to screw things up. I could fix it with a simple where clause but better just to initialize the collection with an empty collection.
Clifford Nelson 16-May-18 13:28pm View
Yes, Copied from working console application. It has been fixed to deal with null Cars property.

Why do you have the ToList(). Should not need that.

What you do is make the DependencyProperty of type bool and Bind the DependencyProperty to the IsChecked value of the ToggleButton.

Still does not do what I want. I wanted to create an application. I have solved the problem, but want to see if I can create something smarter than the windows shortcut. In other words a replacement. I did not ask how to actually do it since there would be little reason to ask the programming community on how to do something in windows. I want to know how to create an editable property in the file property window.
Clifford Nelson 3-May-17 17:05pm View
That is for adding context menu items, not for adding a editable property to an application
Clifford Nelson 3-May-17 17:03pm View
So tell me what happens when you create a batch command. The command window shows as long as the application is running unless specifically closed. Thus for every batch started, two windows will appear. I do not think that is very desirable. You may. In my opinion shortcuts should have supported relative paths, but they do not appear to except through bad workarounds.
Clifford Nelson 3-May-17 14:54pm View
Ok...Here it is. I want to create a very simple application that will be able to open a file using a relative path that can be set in windows explorer by changing the value of a property associated with the executable. The current shortcut only seems to support an absolute path which is useless for portable drives, and a folder copied with shortcuts will no longer work.

I tried. Live Visual Tree does not get information on this new feature. Only for the old Live Visual Tree, don't know what this new control is called, so don't know what to google. I would upload a picture, but codeproject does not support inserting pictures as far as I know.

So why do you point out you have multiple projects. If this is all in the same project... What is in the other projects?

Can't append to a XML document
Clifford Nelson 31-Jul-13 13:05pm View
Yes it seems you are right. I did not try to test my suggestion, and it was only a suggestion. Now that SA has put the input, I can see the issue. I would have probably used a canvas in the first place, so would have avoided having the problem. A low vote with no information is useless.
Clifford Nelson 30-Jul-13 17:13pm View
Somebody downvoted. It would be a nice idea to know why. Do you know for sure this will not work, or do you have the real solution? If so, please share it.
Clifford Nelson 30-Jul-13 15:55pm View
I would stop the code in the debugger and look at the button and it's data context. Also, you should just cast, not use the sender as Button.

Just add it to the question with the pre tags to let it look like code. In a comment like this very hard to read.

I would contact DevExpress on this. If you were using a standard Microsoft WPF grid you might get an answer, but very unlikely you will get an answer on a 3rd party control because there are few people using any one 3rd party control.

That worked. Thanks. May fix some other issues I have had with using resources.

The ResourceDictionary works fine for other styles, that includes ToggleButton, so very unlikely that is the problem

What happens is that the first part would read the text into memory, the second continues after the task has completed, and, if you are on the UI thread when you start, you will be on the UI thread when the task completes. Besides possilby Async, this is actually quite easy.

Happy to oblige. Linq is quite powerful, but can be very confusing (try doing a distinct). It is probably one of the best tools around since it saves so many lines of code.

Using the PreviewTextInput is not a good idea. KeyDown event works just fine. Also, much too complex for what was asked for. Don't have to worry about signs, or decimal points.

That is not necessarily true since cannot deal with context issues with this technology. It works for simple validation, but not validation against other values. Not my vote of 1.

You wake up the service when its time to send the email. Could use a service to start the email application, but still need to trigger the emails, and that requires something to be running to know that it is time to run the application.

Thanks for the comment. It is just text, but still seems that could be quite a few fields, and especially since the link provides a generic to solve the problem, it becomes pretty trivial to save an object.

I did not have an issue with "if(i is jigger<>)" but with "(i as jigger<>).DoSomething();". Should have just done a cast instead of the "as"

I missed the return of T. The only thing you could do is use a return type of object. The only option would be is have T derive from something, and have an appropriate functionality. More than likely T would be derived from some type.

The WPF TabControl has an ItemsControl DependencyProperty, which allows you to have a collection of ViewModels that can control the tabs.

The code can be used to help in creating a way to export data from excel. It also provides an easy way move data to an object, providing the user feedback on errors before actually committing to send the data. It still needs the code to actually do the export, but if you have field headers already defined, it can find those headers and read from there. All that needs to be done is to take the C# object and move it into the database.

YOu fill probably find that Microsoft does not want you to have access to that information, so will not make it easy to get. This is a privacy issue and Microsoft does not want to be liable.

So explain how two way binding works with Command. Command is the ICommand interface, and provides a way to execute code. Not much point in TwoWay with ICommand. Incidently, a ToggleButton is basically a checkbox, which is probably why there is a Command argument.

To ensure that it is a stream, obviously add to the where clause. The complexity, I think, is actually less. The streams already support IDisposable. Also, can just make the Test<t> public, which would make it much more flexible, expecially if it is designed to work with any instance of a class that inherits from a base class.

I looked at most of them, but they do not seem to have anything to do with editing. I have changed the EditMode property with no luck. Maybe if you are an expert with WinForms you can download the project and see if you can see anything. I did not post code because I am not sure where the problem is. It uses TypeDescriptor and PropertyDescriptors. This may cause problems I am not sure. Really do not want to have to go to WPF unless I have to, but I have to admit that maybe I should since WPF is so much more powerful and I am much more comfortable with the technology.

Clifford Nelson 23-Aug-12 17:33pm View
Yes. I have tried changing a bunch of properties on the grid, but nothing seems to work. I am probably missing something minor. I just do not have a lot of recent experience in Windows Forms. Once I have editing, I can allow the information to be changed, and validate the changes.

If you were interested in associating the two, the best would be to have the empolyee record have a department property, and the department have an employee collection. Then it is really easy. What you end up with is a parent child relationship where the child points back to the parent. This is quite common, and if you investigate a lot of the objects that are written by Microsoft you will see a parent field that points back up the chain.

Have you tried coding your solution yet????
Clifford Nelson 13-Aug-12 17:14pm View
Since obviously somebody has also been mislead (voted you a 5 when you are wrong and don't know it), I will explain better. In a base system you have a 0 and however many numbers as you specify. If A is zero, then you would have a never ending set of A's when you have any mod. So A is one. Then what is AA. You would think obviously 27, but it is not since Z is 26 and then A? (where ? is the zero value would be 27, and AA should be 28. If you take A as zero instead, then after Z would increment to BA (1 = B, 0 = A), that's not right either.
Clifford Nelson 13-Aug-12 16:35pm View
So I did not explain it so well. Best thing is for you to try your code. Do some work. that will prove it. If you can post code that works with simple base 26, as I said (and you ignored), I will give you a five.

PS. My code will work with three letters, and I posted both the coversion to and from.
Clifford Nelson 13-Aug-12 15:29pm View
I voted it down because it is wrong. It is not a straight base 26 because there is also the blank. You did not test it. If you can create a example that uses straight base 26 I will correct my vote. Wish it was so simple. Also, did not provide the code. You shot from the hip, and missed by a mile. Next time spend a little time testing your concept before posting.

Must be that you want to save a file on a remote system. Am I correct. Otherwise it is just using the Open/Save dialogs. If you do want to save/open to a remote system, you have to have installed program on the remote system because Windows does not like to allow remote access to a oomputer for obvious reasons. One way to do this is work thru the PowerShell remote features.
Clifford Nelson 20-Jul-12 18:04pm View
That is probably because you have to be specific. In other words, you need to set margin on particular controls (ie TextBox, TextBlock, etc). I have never seen anybody attmept to set properties for Control, or any of the other elements that are not concrete.

When you talk about no code behind, are you looking at an MVVM solution. XAML is somewhat limited in do any sort of calculation, so sum/count would be a little beyond it. I would like it if Microsoft had continued to develope XAML since I think it could do so much more.

I totoally agree. One of the issues I have with Visual Studio is that sometimes something builds on one machine but not another because of things left in the bin folder.

We have been looking at AutoComplete TextBox here, and had all sorts of problems. For whatever reason, it is difficult to get the combobox to completely work right for this feature. There are some really strange interactions. We also decided to go with the WPF toolbox version.

There are too many ways to write dates that can be confused. If at least the month is written out or abbreviated (no numbers), you have some hope of being able to distinguish the dates. However it is common to write dates in the form mm-dd-yy and dd-mm-yy. You can only hope to make it out. This means that you con sometimes only guess.
Clifford Nelson 25-Jun-12 20:23pm View
I would look at exactly what you are getting back from the C program. That way you can see the exact bit array out vs. the bit array in. That way you can determine exactly what it is doing.

Thanks, I forgot about that. Could have been clearer on you answer. In this case the default was not lost focus, but the row looses focus. Give you a 5 anyway, especially since you were the only one able to answer the question. In this case the problem is that you restated what Microsoft has on thier site, and Microsoft has some of the worst documentation of anybody. The article you gave as a link is just so very bad. Probably would not have been accepted on CodeProject.

Don't know, it works in WinForms, and I have not done enough to know.
Clifford Nelson 17-Jun-12 17:50pm View
I would differ with you on that. In fact it is sort of sad that it no longer is supported. It was much easier for non-programmers to learn. VB.NET has a pretty steep learning curve (in fact I think that there is no reason to use VB.NET, just use C#). Obviously, not very good for professional development.
Clifford Nelson 16-Jun-12 0:47am View
You need to tell us the environment: ASP, WPF, WinFOrm, and probably be more specific about the grid technology.

DO up vote. Whenever I upload to CodeProject I remove the bin, object, snd for single project solutions, the solution files. I have had problems in the past where things work because I have old dll's in the bin folder, and somebody else cannot run out of source control. Good idea to delete these files sometimes to make sure you are not running because of legacy files.
Clifford Nelson 8-Jun-12 12:13pm View
Are you doing winforms or WPF?
Clifford Nelson 7-Jun-12 19:06pm View
I know. I am actually surprised that I cannot find anything better. I beleive you can make a brush out of pretty much anything, and then paint it on a surface, but then being able to interact with it is another problem. Too bad Microsoft has so reduced its support of WPF/Silverlight.

You can do this with the XamDataGrid using the pivot table. You can also do a custom grid where you create a control class inheriting from grid.

How about providing information on how to do it with JavaScript. Link to an article would have been very helpful.

It appears to me that you are reading only the first row of the excel sheet. You will probably be better off using the excel interopt.
Clifford Nelson 21-May-12 11:37am View
That tells me that a row has not been selected (clicking the button obviously does not cause the row to be selected). You may be able to cast the sender. and get parent. Not sure since do not have code

Clifford Nelson 20-May-12 23:14pm View
You are wrong on several accounts.

First of all you don't even want to have the data in the form class, you want to use MVP/MVC. However that is much more complex than just using another class. I do not see much point in using another class for just this communication.

There are good reasons for there to be a child form that does not prevent access to the parent form. The Microsoft Office Find Replace dialog is a good example. Users get use to being able to go between the two. I could give you tons of examples where you might want to do this.

I have never been a fan for MDI form, and seems that it is one its way to oblivian, thank god
Clifford Nelson 20-May-12 22:01pm View
There are no user settings, but the question did not indicate that it had to be for user settings. You are now making the assumption, and you are attacking me for my assumption! Amazing the arrogance.
Clifford Nelson 20-May-12 21:54pm View
Apparently you are the one that is wrong: Yes, you can use Settings.Settings files for web application projects. Set it up just like in your WinForms projects. With a web project, you are limited to Application scope though - you cannot create user-scoped settings.

Just go to project properties, and Settings, and it lets you create a settings. You are the one that now has egg on your face. How do I give you a one for being so positive your are right when you are wrong......
Clifford Nelson 20-May-12 21:35pm View
You never make an assumption? In the environments I am familiar with Settings work, and that is pretty much every other environment in Visual Studio. So next I guess I cannot give advice on adding and subtracting in ASP.NET because maybe it is different in ASP.NET from WinForms, Silverlight, WPF, Console.
Clifford Nelson 20-May-12 20:31pm View
You still are not giving enough information. However, if you are using Visual Studio, you can open the Server Window, and there you select the database type (it can be a database file). It should be able to guide you through finding the database. If you an an entity framework file, this will create the connection string, putting it in the config file. Hope this helps more.

Incidently, whoever gave the one, are you being an a**h*** or do you have a reason for the 1????
Clifford Nelson 20-May-12 20:25pm View
I am so very sorry, such a horrible mistake. Not an ASP.NET developer. Was able to use the Settings on Silverlight. Assumed, obviously a really big big mistake since I assmume you gave me the 1,

In the newer frameworks it is recommended that WCF be used for Web Services. It is not that hard to set up a basic Web Service in WCF. Then if you need to enhance with security, or whatever, you will find it is much easier. WCF has been available for 4 years, almost half the lifetime of .NET. Time to move up to WCF. To see a very basic example look at

Hope this helps somewhat.
