I have written an application in VB.Net to be run in Windows CE. In it I have a combo box that is populated with numbers representing items that the user will select and use and are then removed from the list. Specifically, a file is maintained with all the numbers that could be in it and a flag is set that tells the program whether a particular number has been used or not. Every time we return to the screen with the combo box on it, it is repopulated.
When we get down to having only 3 selections or less available, the combo box opens when the down arrow is clicked and immediatley closes before a selection can be made.
Any suggestions as to how to correct this problem?
Also, the point at which this problem occurs changes when certain things are changed about the combo box. For example:
The font for the combo box is 9pt currently. If I change it to 12pt, the problem doesn't occur until we get down to only 2 items in the list.
I also moved the box to a different location on the screen and it started occurring with 4 items left.
Any help would be appreciated.
Thanks,

is there any way to, when adding subitems, to skip over a collum and put data in another. Say for example you have 6 collums and you already have data in the first 2 collums and want to skip the 3 and put data in every collums after 3. how would you do this?????

Hi everybody
I need some help! I created an AVI animation to display in a form
but i can't understand what color I need to use to have the background
transparent (the mask color). I tried with FUCSIA but it doesn't work.
I designed the bitmaps with Paint and converted to AVI using Virtual Dub.
Any Idea?
Thanks in advance
OS: Win 2K
SDK: Visual Studio 6/Visual Basic

IIRC, you can't set a transparency in a movie and expect to see the form behind it. The WMP control that's displaying the movie doesn't support a transparent background, if that's what your using.

I'm using the animation control (part of MS common controls). The strange thing is that with sample movie clips in Visual Studio (for example, the file copy or computer search) the trick works good. The AVI has a fucsia background and the color of the form behind is displayed.
What do you think? 
thanks in advance Dave

I've never used the thing.
But, I've found an abscure reference that says that the pixel in the upper left corner of the first frame becomes the transparency key color. But, this does NOT make the AVI transparent, rather it substitutes the parent containers background color (in your case, the form color) for each pixel that has the transparency key color. This makes the background color (or transparency key) match the host container color.

That's amazing!!!!
It's what I was looking for!!! In fact I don't need to have my AVI with a transparent color but I only want to use it with a masking color for the background.
Thanks a lot Dave

Hello, can someone help me, i want to move three sliders at the same time, like the Volume Control on Windows, i've tried a lot of thing but without any success, can someone help me to do it, please?

Off the top of my head, handle the Scroll event of each slider. Set the Value of the other two sliders to the Value of the slider being changed.
Don't know if this will work at all considering I haven't touched VB6 in years.

Thank you for replying Dave, i don't want to move all with the same value, a good example of what i want to do is the Windows Speaker Volume, when i check to move the sliders at the same time, it will do, event if they have different values, please, "play" a little with that to see what i'm trying to do and if you can help me!!
Thanks,
UltraMAX

You'll have to track the values seperately from the control's actual values. When one of the sliders changes, calculate the change from the last saved value and apply the change to the other values and control's actualt values.

i m getting this error (on Execute line) when i m inserting Data in database....
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in tab.exe
Additional information: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 3.
Public strSQL As String
Public objCon As ADODB.Connection
objCon = New ADODB.Connection
Dim Rs As New ADODB.Recordset
objCon.ConnectionString = "MaxBufferSize=2048;FIL=MS Access;DSN=Scan;PageTimeout=5;UID=admin;DBQ=D:\VB.Net\VulnerabilityAssessment.mdb;DriverId=25"
objCon.Open()
strSQL = "Insert Into RemoteHost(HostIP, HostAddress,ScanTime)"
strSQL = strSQL & " Values(strIpAddress,Host.HostName ,Date.Now);"
objCon.Execute(strSQL)
objCon.Close()
objCon = Nothing

You didn't evaluate any of your variables at all. You should have done this:
strSQL = "Insert Into RemoteHost(HostIP, HostAddress,ScanTime)"
strSQL = strSQL & " Values('" & stdIpAddress.ToString() & "', '" & Host.HostName & "', #" & Date.Now().ToString() & "#);"
objCon.Execute(strSQL)
Even then, concatentating SQL statements together like this is a major security risk and can get your SQL tables wiped out.
I would suggest using parameterized queries as explained in Colin Angus Mackay's article, here[^].

Hi,
I make a small project in Vb.NET, it also have some crystal reports. The reports works well in my computer. But when I run my project on other computer, the reports cannot runs well. Actually it gives a dialog box and ask to Enter "Server name","Database Name", "Login ID", "PAssword"
Why this happens when my project runs on other computer.
Plz give me a possible solution.

Use ODBC in Crystal reports for getting data and build ODBC on the Client side after installing the application. Will solve every thing

Gosh, I wasted alot of time playing around with this.
An ODBC direct link is fine, as long as your data source doesnt change. eg: your software goes out to a customer, with different servername, database name, login, etc.
You can program vb to change the the datasource information at runtime before the report loads. Thats gives you better customisation.
Or alternately, as I have come to realise, do all your data selection in vb, and pass a dataset to CR instead. When designing the report, run your program quickly, but include a dataset.writeschema (c:\myschema.xsd)
Then when you set the datasource for the report, choose xml.
So much easier, neater programming, better maintainability. The selection criteria in CR becomes redundant (which is a blessing).
Or...
yeh, if its just 1 report in your office, odbc links are fine!

In my VB program Irunning on WIndows 2000 have a WindowsMediaPlayer1 object and an Image1 control and a Scan button that executes the following command:-
Private Sub Scan_Click()<br />
<br />
Image1.Picture = Clipboard.GetData(vbCFBitmap)<br />
<br />
End Sub
So basically what I want to do is press the Print Scrn button and then press the scan push button on my form to copy the Clipboard onto the Image control.
Now the problem is all I want the clipboard to contain is the image at that instance on the Media Player.
Currently I get the whole desktop.
Are they anyway I can limit the clipboard to just capture the WMP image. Someone said use Device Context (DC), but never used them before so would like some notes in the code.
Many thanks,

Pressing PrintScrn captures the entire Desktop window. Pressing Alt-PrintScrn captures the current window, which in your case, would be the entire MediaPlayer, content and all.
You'd be better off using the MediaPlayer or MultiMedia API's to grab a single frame.
