Hi again!
My project is done and now I want to add icons to it.
I read that I can do this by selecting the *.ico file at the settings.
As I tried that, a error message poped up. The text was something like "32x32.ico is not a valid system file." I also tried a icon with 16x16 pixel with the same result.
I'm using Microsoft Visual Basic 2005 Express Edition if that has something to do with it.
I also added the file to the resources directory of the project.
Does anyone know how I can add Icons to the project?

|

I treid an other way to add the icon and a error warning popped up that said that this file cannot be used as an icon (but it is a *.ico file).
I use the freeware PixelToolbox 1.1 and create a 32x32 pixel windows icon with 4bit depth.
Do I use the wrong program, or wrong settings?

It could be that the app isn't outputing the correct file format. You might also want to try making 256 (8 bit depth) color icons, not 16.

I "solved" the problem by using another icon creator.
Setting another colour depth had no effect.
Thx much

I know you already solved your problem, but I thought I would send you the link to an article I wrote on this subject. It is pretty basic using simple tools. It sounds like the icon create you have may be the better thing to use.

how can i sort array in vb
|
|
|
|
|
Easy way to answer Ur question:
For i=0 To N-1
For j=i+1 To N
if Array[i]< Array[j] , then Swap the elements Array[i] and Array[j]
Next j
Next i
N-> Index of Last element.

Why rewrite what the framework already offers ?
This is a bubble sort, it's quite slow.

I think this is selection sort.
Bubble sort would be: (in C Language)
for(i=1;i<n;i++)
{
for(j=0;j<n-i;j++)
{
if(a[j]<a[j+1])
{
swap a[j] and a[j+1];
}
}
}

Yes, it is the slowest sort.QUICK sort will be the most quickest.

I'm not sure, I think it just has the best marketing team :P

You can also take advantage of the sort method found in the Array class. Just pass your array to Array.Sort. The method is overloaded and can take a number of different parameters.

I have a vb.net 2005 form that calls up another form to add or edit a record in an Access 2003 DB. All that is on this add/edit form is labels and text boxes. I have a primary key and when I add a record it works just fine, but when I try to edit a record I get the following error....
"Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
Here is the code that I am using, I have stepped through the code and everything seems to be functioning just fine right up until I get to the Update line below, that is where I get the error.
Me.Validate()
Me.SurgeonsBindingSource.EndEdit()
Me.SurgeonsTableAdapter.Update(Me.AnesDataSet.Surgeons)
Can anyone help me track this down? I am really at a loss. I bet it is something easy but I just can't seem to figure it out. Thanks for any help that you can give!

Once you give the SELECT command to the DataAdapter, you can use an OleDbCommandBuilder[^] class to automatically generate the INSERT, DELETE, and UPDATE sql commands for the DataAdapter. These are all necessary if you want to do anyn updating of the database from the DataSet/DataTable you filled with the Adapter.

If you're using a DataAdapter and doing updates back to the database through that Adapter, there is no choice. You MUST provide the other SQL commands, either by using the CommandBuilder, or by supplying them yourself.
If you're not calling update on the Adatper, then you don't need the other commands. There is simply no getting around this if you use an Adapter.
There are, of course, other ways to fill a dataset and writing data back to a database without using a DataSet.

Hey Dave, thanks for you input on this. I am probably not explaining things correctly so I will try to do better. This function that I am using works on on less than 18 other tables in my project with no problems.
Here's an example of what I am doing in a working function...
If txtDrugUse.Text = "" Then<br />
EditRow.SurgDrugDesc = String.Empty<br />
Else : EditRow.SurgDrugDesc = Me.txtDrugUse.Text<br />
End If<br />
<br />
<br />
'Update the record<br />
Try<br />
Me.Validate()<br />
Me.Pat01SurgeryBindingSource.EndEdit()<br />
Me.Pat01SurgeryTableAdapter.Update(Me.AnesDataSet.Pat01Surgery)<br />
Catch ex As Exception<br />
MsgBox("Update of Surgury Table Failed")<br />
End Try
Now I that have this working just fine all over my project and that is why I don't understand why I suddenly need to use a CommandBuilder to do the same exact thing that works everywhere else. Any ideas?
One thing that I have noticed, and I don't know if it has anything to do with it or not. but when I type in Me.Validate it takes it but from the drop down list that comes up it isn't listed but ValidateChildren is listed. I don't understand why and it might not have anything to with it but I am completely at a loss here.

Did you use the Designer to add these tables to your code?? It sure looks like it. In that case, the CommandBuilders have been put into your code automatically by the designer.

Yes I did. I created the Dataset and then I drug the needed tables to the designer.

Hi All,
I have the application developed in MS Dos Basic 3.0.
I want to convert or reverse engineering that application into .Net 2005 C#.
Kindly provide me suggestion or ways (any kind of parser is available).
thanks in advance.
Mack

The only choice you have is to analyze the source code of the app and completely rewrite it from scratch. There is NOTHING that will convert old DOS Basic code to anything in use today.

I've been writing a bunch of little apps exploring various controls, components, etc.I have two minor issues, wondering if anyone could help.
First, when I build the apps to run outside of vb express, they all seem to require internet access to run.If I don't create an exception in my firewall for each app they crash on execution.
Second, When using the FileSystemWatcher object, if I save a file from the internet to the watched directory, I get double File Created events.Is this normal?
Eric.

Don't know what this is. You don't need internet access to run the app. It would probably depend on what controls you're using.

Yes, it is. The FSW depends entirely on HOW the application is doing the file work. In the case if IE, when it downloads a file, it's downloaded to a temp folder using a temp name, not the real filename. When the download is done, the file is copied to the actual destination folder (Creat event #1), then renamed to its real filename (Create event #2).

Thanks for answering.
Regarding question #1:
The apps in question aren't using any network or internet related controls.Just your basic combination of buttons,text boxes, notifyicon, etc.I guess I'll try a network sniffer and see what they're doing.
Regarding question #2:
If the FSW is only watching the destination folder, shouldn't the file created event in the temp folder be ignored?
Eric.

That would be my next move.
Emetz564 wrote: If the FSW is only watching the destination folder, shouldn't the file created event in the temp folder be ignored?
It is being ignored. The FSW only watches the target folder. When it starts, it enumerates the files and their Created and Modified DateTimes, along with other things. Every once in a while it makes another list and compares the two.
When a new filename shows up or a file with the same name has a new Created time, it fires off the Create event.
If a file disappears off the list, Deleted event.
If a file has a new Modified DateTime, the Changed event.
Now, Renamed is a bit different. The FSW CAN detect a renamed file, but, for some reason, not in all cases. It depends on what the application is doing that is modifying the files. Either the Renamed event is going to fire, or the Created event will fire, maybe along with the Deleted event. It probably has to do with a timing issue when the FSW scans the target folder(s).
