This is so wrong. You shouldn't be moving controls between forms, the controls shoudn't even be visible between forms. What a disaster.
To communicate between forms ( passing text to set labels, for example ), form2 can expose a property that form1 sets ( a string that sets the label ), form2 can take the string in it's constructor, or you can set up delegates to pass the info between forms based on some event in one form.

i dont need to add it to the resource file i need to add it to the Application file list so that i can deem it a data file and the program will place the file in the correct place to be accessed by the program otherwise when i install the program it looks for the database and cannot find it, then errors out and shuts down the program. Unless anyone knows a different way to tell the installer to copy that database file to the correct path?

You haven't really specified what it is that you need help with. To "move objects" could be anything from animating cards in a solitarire game to simulating three dimensional real time physics.

Sounds to me like you're one of the many people who try to write games before first learning enough core concepts to stand a chance of completing a game project. There are books on how to write games, I suggest buying one, but also working on knowing the core of your language better before adding DirectX to the mix.

Yeah, when I read graphics forums, they were full of 'I just found out about C++, who wants to join my team to make a killer 3D engine, it will be better than all the others, and do xxx and yyy and zzz, even though those things are not possible with current technologies'.

Hi.
I have a web application, which runs on the server. The application supposed to access folder on the Intranet (provided by user), grab some files and read them. The problem I have is the security. Some folders on the Intranet are not accessible. What happens is when user provides directory address to my application I cannot access the folder due to access denied error. How can I go around that? In my web.config file I have set but still it doesn't work.
Thank you,

I want to get data from excel file and fill data into DataTable via OLEDB. But header of DataTable is always the first row of excel file.
Exp : i have data in excel file :
John 29
Kevin 27
Kex 34
When i fill it into DataTable, header of DataTable is (John 29). And i don't want that. I want (John 29) is the first row of DataTable. So how could i solve that?
code :
Dim cnn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Info.xls;Extended Properties=""Excel 8.0;HDR=YES;""")<br />
Dim da As New OleDb.OleDbDataAdapter("Select * from [Sheet1$]", cnn)<br />
Dim dt As New DataTable("TestExcel")<br />
da.Fill(dt)

Make the first row in your excel document your header row.

Hi,
I have a piece of code which reads the contents of a cd to and image file using a DOS command line program. While this is running the main window becomes frozen. Does anyone know how I can create a thread that deals with the command line program so that the window does not freeze.
Thanks

Let's see the code your using to launch this command line process and interact with it. Usually, something like this doesn't block your interface, unless your doing a WaitForExit on the Process object.

Hi,
This is the code I am using to launch the command
Dim command As String
command = "C:\readcd dev=1,0,0 f=c:\johntest2.iso"
Shell(command, AppWinStyle.Hide)
I am also hoping to display a message when the command has finnished.

Are you using VB.NET or VB6??

Sorry Dave. I am using VB.net 2003.

OK. The code you posted is old VB6 stuff. But, in either case, Shell isn't a blocking call, so... There's something else that's hanging up your app. Is it possible that the app you launched is taking up 100% of the CPU??

Hi
The app probably would be using most of the cpu time. I came across the process.start which seems to help. Would this be the best thing to use.
|
|
|
|
|
Yep. Launching a new process automatically give it it's own thread. It's not dependant on the threads of your app, so launching another thread won't help.

My textbox is bound to a datatable field. The field length is 50. I set the maxlength of the textbox to 50 also. When I run the form I cannot modify the textbox until I delete the trailing spaces. Can the trailing spaces automatically be removed so the user does not have to do it when modifing the textbox?

|
|
|
.Trim()

If you are able, you should tackle the root cause.
If you use a varchar in the database instead of a char then you won't get trailing spaces in the first place and you'll probably make more efficient use of your database.
In general you should only use char for interaction with legacy code that doesn't understand variable length columns or if you know that the data in the column will always be a fixed length.
