I am getting this error:
"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
Field in MySQL is defined as a LongBlob
Any help would be appreciated.

Hi
I have a small problem...I have some game located in say D:\MyApps\mygame.exe
I need to launch mygame.exe using my vb.net application...
I used Process.start("D:\MyApps\mygame.exe") ...but it is not working .
If I place my application in D:\MyApps\ and use Process.start("mygame.exe")..it is working fine
Can somebody pls help...tnx in anticipation

This MUST work in VB.NET fine (since I have used it a lot!). In C# you should only change \ to \\ to work...
|
|
|
|
|
Well...it is working fine now since i have used Chdir to change the working directory to that of the game and then using Process.Start

I am having problems with the Windows Media Player used in an application. I changed to Visual Studio 2005 from Visual Studio.net and my programs will not work. So I made an application from scratch that worked in the old version. Here is a link to the code and instructions, (Playing Digital Media in a Visual Basic .NET Application), that I am using: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwmt/html/playingdigitalmediainavisualbasicnetapplication.asp
At the top of my code when I reference the PIA namespace (Imports Microsoft.MediaPlayer.Interop), I get an error that it doesn't contain any public member or cannot be found.
I am not sure if the PIA registered correctly, because it is not in the default location that the regpiagac utility, (located in the tuneclipper sample of the Windows Media SDK), shows it.
So I reran the regpiagac utility and here’s what happened step by step:
This utility will register the PIA and add it to the GAC.
OK
Please verify the path to the Regasm
C:\Windows\Microsoft.NET\Framework\v1.0.3705\ (default)
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 (actual)
OK
Please verify the path to the Gacutil
C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin\ (default)
C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin (actual)
OK
Please type the path to the Wmppia.dll
C:\WMSDK\WMPSDK9\redist\
OK
'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727regasm.exe' is not recognized as a
n internal or external command,
operable program or batch file.
'"C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bingacutil.exe"' is not re
cognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
Any help will greatly be appreciated,

Ok, I left a slash out of the end of the path and I was able to successfully register the PIA. I no longer get the error for (Imports Microsoft.MediaPlayer.Interop). My old programs still don't work, and I still have issues to deal with, but will try to work it out, and if unsucessfull I will add a post later.

How can i maintain a printer log?
|
|
|
|
|
If you only require a list of documents printed, have a look in the event viewer.
If you want full details you need to monitor the printer - there is an article in my articles on this site that is called "Monitoring a printer from VB.net" that is a good starting point

I am trying to fill a DataTable with data from sql databae by using Background worker but it throws an exeption (calling it from the main thread works fine). I have read that BackgroundWorker can be used for database operations but can't find any examples. Here is the code:
Dim conn As SqlConnection = _
New SqlConnection(connectionString)
Dim command As New SqlCommand(cmd, conn)
Dim adapter As SqlDataAdapter = New SqlDataAdapter()
adapter.SelectCommand = command
Dim table As New System.Data.DataTable
table.Locale = System.Globalization.CultureInfo.InvariantCulture
adapter.Fill(table) ' the exeption is thrown here
What should I do? Please help.

Hi 2 all!

I have heard of some experimental ports of the .NET platform to Linux, but I suspect that they won't cut the mustard. .NET is really designed for Windows and not a cross-platform framework. Have a search on the web in the Linux newsgroups etc. and see what you can turn up.
As far as development languages are concerned, I think you'll find that C++ is almost universally used. Good compilers are available from GNU and any Linux development web site should have more links than you can poke a stick at.

Actually, ROTOR & MONO (the Linux .Net runtime) has come a long way. You can write .Net for Linux, though I believe C# is your only option. IDEs are somewhat limited though, SharpDevelop has a Linux port, and I've seen ads on CodeProject about Grasshopper for Linux .Net though I haven't checked it out yet.

Thanks for the references. I'll check them out.

It is posssible. I don't know if there is a tool for making it under Linux. But I know that MONO is something like for .NET framework for Linux. You can use VB.NET or C#, Managed C++ programs do not work with MONO.
While programming try to avoid Windows specific operations (such as reading/writing the registry etc.)

Hello!
I have written a little subrutin to clone and mirror a panel into another form.
I would like to grow the size of clone. (zoom)
I tried ScaleTransform but it's not work.
Here is my code:
Private Sub CloneMirrorZoom()
Dim b1 As Bitmap
Dim g1 As Graphics
b1 = New Bitmap(Me.Width, Me.Height)
g1 = Graphics.FromImage(b1)
g1.CopyFromScreen(Me.Location + Panel1.Location, Panel1.Location, Panel1.Size)
g1.ScaleTransform(2.3F, 4.5F)
b1.RotateFlip(RotateFlipType.RotateNoneFlipY)
Form2.CreateGraphics.DrawImage(b1, 0, 0)
End Sub
Please help me, what is wrong?
thx.LD

If you applay ScaleTransform to a graphics object it doesn't mean that the current contents gets transformed but that all coming drawing operations gets resized. In this scenario you won't need ScaleTransform at all:
b1 = New Bitmap(Me.Width, Me.Height)
g1 = Graphics.FromImage(b1)
g1.CopyFromScreen(Me.Location + Panel1.Location, Panel1.Location, Panel1.Size)
'g1.ScaleTransform(2.3F, 4.5F)
b1.RotateFlip(RotateFlipType.RotateNoneFlipY)
Form2.CreateGraphics.DrawImage(b1, 0, 0, b1.Width * 2.3F, b1.Height * 4.5F)
Also think about painting the image in the form via its Paint event instead of drawing it here directly. You could do this by setting some field to the generated bitmap and calling invalidate on the form. After that the Paint event will be thrown and you can draw your image there.
Also never forget to dispose created Graphics instances.

hi,
i want design a windows application where i'll give a word document as input. from that document i have to separate only the email ids and store it in a separate file. how to start? anybody give me a clue or a skeleton of this task

Hi,
You will have to create temporary Word document object in your project. Then on some event like button click write code to attach the word document to this temporary object and use the object to send commands to word document. Now for the email addresses part, you can use the regular expression class Regex for that. just search for it in msdn.
