So you decided on cheating all the time, hoping to have a slightly better chance of being the first at it?

Next people will start and claim it is my fault the average reply quality is going down...

I should have put a joke icon on that post Luc, I don't take it that seriously. If someone else answers a question that's great, so long as the OP gets the correct answer which this time he did - twice.

In this case I read the Subject 'Create a bmp' and read in the post '1 x 1' so went ahead and answered. I then reread the question (as I always do to make sure I have given the fullest answer I can) and noticed he wanted a bitmap file so I modified my post to show how to save it to a file. In the minute or so whilst I modified my post, Henry had posted his answer.

No cheating, no battle field - and all in good spirits trying to help the OP from me and Henry Big Grin | :-D

This sounds as if it could be for something naughty.
But I don't care, today, so:

BitMap bm = new BitMap(1, 1);
bm.Save("C:\Windows\Temp\NefariousBitmap.bmp");

I am needing this to prevent MS Access from bringing up it's splash screen when ms access loads.
Since you need to place a bmp file in the same directory as the mdb file with the file names being the same just the extensions different.

Using my application to open a file

I have developed an application that works with xml files. I have allowed users to open an xml file with my application. This I have done using the Main(String [] args) function. But the problem is the application name is not being displayed along with the application icon when the user right-clicks and chooses "Open With" in windows explorer. Would I need to make any registry entries for this to happen, or is it something I can do within the application itself? I'm currently working with the Microsoft Visual Studio .NET 2003 IDE. Please help.

You can write to registry using C#. Please search it in MSDN.

OK... I have successfully written to registry, my application is assocciated with all xml files on the computer and by default my application opens when you double click on an xml file

However am still having the same problem. when you right click on an xml file and select the "Open With Menu" my application is listed with my application icon but my application name is blank...

How can I get the application name to display beside my application Icon On Open with menu?

could this be a setting on .Net?

C# Excel and Threading

Hi There,

I have a background worker thread on my Form.

In 'DoWork' A call is made from the thread to pump data out to Excel. The visible property of my Excel Application is set to false until 'RunWorkerCompleted' (there may be a lot of data and the users don't want to see it being churned out) when visible is set to true, I also use the .Activate method :

excelApplication.Visible = true;
((Microsoft.Office.Interop.Excel._Workbook)excelWorkbook).Activate();

Everything works fine except the Excel appears behind my form - not the front.. annoying .. in addition its only happening on my tester's machine (typical!) and not mine. It is the last code that executes.

excelApplication

and

excelWorkbook

are in a different class which I suspect is the root of the issue, also it needs to be inside the thread so the UI is not affected when the form is moved around and such like.

Any ideas?

Thanks very much

Jon

Hi there,

I don't see why you need the below call, just setting visibility to true works fine for me:

((Microsoft.Office.Interop.Excel._Workbook)excelWorkbook).Activate();

You are right that you should not have the application and workbook objects in different classes. I doubt that is causing the sheet to appear behind your form though.

Have you tried a simple send to back call on the form after you make the sheet visible?

Cheers,

Thanks Mark,

I will try the back call.

Sorry, was a rather vague there, my Application and Workbook objects are in the same class (Excel class) which is not in the Form class (obviously).

Thanks very much for the help,

Jon

You can try with GemBox spreadsheet component. It's much better way to read and write Excel file then Excel Automation.

State map with markers,info windows

shultas28-Aug-09 6:59

Hi Everyone-

I have built a help-desk application that allows agents to create tickets with issues that our technicians are dispatched to resolve. Our company for the most part operates in three states. What I am looking to do, is have a section in the application that displays a map of our region, with the three states visible, with markers or pins on them.

The idea is a new call comes in with a problem in a city. The dispatcher can look at the map and see markers/pins of all of the technicians and where they currently are. The dispatcher can then make a determination "Steve is only 10 minutes away, lets send him after he is done with his current call".

I am wondering if anyone knows the best way to go about doing this for a C# Windows Forms application. I was tossing around the idea of having a browser window somehow interfacing with Google Maps to tell it the area I want to display along with the pin/marker information, but was wondering if any of you could point me in the right direction! I would really like to accomplish this without the need for a local web server if that is possible.

TIA!

If the PC is always online, the use WebBrowser control, open google maps, and put some coordinates in it. That is the easiest way.

That's exactly what I would like to do! I have been searching for a little while as to an easy way to open google with coordinates. Everything that I have found so far requires custom web pages with all of that jazz. Any suggestions as to easy way to add points/coords to google map from within a browser in C#?

See Google Maps API :

It use JavaScript. Just create a HTML + JavaScript code and show it in WebBrowser control.

Hi,

Can someone tell me a MODULO algorithm like google's, typical calculator's, excel's, etc?

Because, they all return 0 for:
4029800 mod 100

But C# (and java I think) return -10

Could you show the code? That really isn't what should happen, not in Java either.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
