You have to use the KeyDown event because the KeyPress event only registers keys that represent characters.

Hi all,
I have a process that run lame.exe to encode an mp3. What I am trying to do is catch the ouput from lame and display it in a textbox. So what i did was this:
<br />
'create a new process<br />
Dim p As New Process()<br />
p.StartInfo.RedirectStandardOutput = True<br />
p.StartInfo.UseShellExecute = False<br />
p.StartInfo.FileName = "C:\Lame\encoder.bat"<br />
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden<br />
p.Start()<br />
p.WaitForExit()<br />
mainForm.txtResult.Text = p.StandardOutput.ReadToEnd<br />
p.Close()
This doesn't produce any errors, but it doesn't work either. I basically just want to show the user that something is happening. Ideally I would like to have a progressbar but i can't think of a way to measure the progress of the process. Anyway, if you can help that would be much appreciated.

I have an application that has a web browser control (VB6) in a vb.net app. How can I write a javascript action that will call a function/sub or fire an event in the vb.net app containing the browser control. e.g. htm source code: <input type="button" value="Test" onclick="CodeThatWillPassIntoVBApp('DataToSendToApp')">.
<script>
function CodeThatWillPassIntoVBApp(DataToSendToApp)
{
//As if by magic - data is sent to vb.net app
}
</script>

Hello all,
I have an Access 2000 database. On a table called "Images" I have a field called "Link to Images." This field is hyperlink to some imgae files I have. The hyperlink name is generated based on an ID number given to them as they are entered to the database (the number increases sequentially).
I made a program that will take the ID number of it and create the appropriate hyperlink name. The problem is though, it doesn't create an actual hyperlink. The field gets changed to what I want, but it is not an ACTUAL hyperlink to the file.
Is there a way to write a program that will automatically create the hyperlink? I don't want to sit and manually type the name of 900+ images into my database.

What do you mean by this? What makes it not be an actual hyperlink? The fact that it isn't clickable? If so, all you have to do is change the data type to hyperlink in the table's design view.

Sorry maybe I wasn't clear. I wrote a Standard EXE VB program that connects to my database. In the Database, I have a field that are hyperlinks. Thus if I open the table, and click on the hyperlink, it opens the image.
So let's say I open my Table, and run the code, then I can see the hyperlink name change to what I want. My problem exists where when I go back and click on the link, nothing happens.
So I right clicked on the hyperlink in the Table and looked at the Hyperlink properties. The "Text to Display" has been changed by my program, but the hyperlink itself is blank. Basically the hyperlink is there, but it no longer actually links to anything. If I go through and reenter the hyperlink manually this way, it defeats the purpose of my program.
Any ideas?
It'd be really great if I could get this to work.
Thanks
Nick

Could you post the code you use to actually do the changing?

I have the flexgrid. When the row is selected I am assigning value to the text box array.
Text1(0).Text = fgrid1.TextMatrix(Y, 1)
As you can see I am taking each column and assign the value to a text box.
instead of assigning the value of each column to a text box is it any other way to do it?

I am working on an image editing application, and I was getting a noticeable screen flicker. Is there a way to override the WM_ERASEBACKGROUND message that gets sent during a Refresh? I have a bitmap in memory that I am copying to the screen, so erasing the background during a Refresh doen't do anything besides irritate me.
I have come up with a workaround - I created my own screen painting subroutine and changed some of the Refreshes, Invalidates and InvalidateRgns to run my subroutine instead, but I still would like to know if there's some flag somewhere that you could set.

Hello everyone,
I am having a crazy problem, and cannot find anything on the Internet
as to why this is happening.
I have a project folder, in which I have a Database folder.
+Project (Folder)
Project files (forms)
+Database (Folder)
Database files
+XML (Folder)
When I make an OLEdbConnection from a form in my project files folder, the absolute
path looks like this
D:\Documents and Settings\j\Desktop\DEVELOPMENT\GradID\Database\GradIdentDB.mdb
when I test the connection, it works.
however, I want it to be a relative link so I set it up like this since I am
in the project folder and want to go down into the database
folder.
.\Database\GradIdentDB.mdb
However, when I test the connection I get this error.
D:\Documents and Settings\j\Desktop\DEVELOPMENT\GradID\Database\Database\GradIdentDB.mdb
Notice the two "Database" in a row, it's as if my project is in the Database
folder. Understand?
The relative link that works is .\GradIdentDB.mdb
Again, it looks like Visual Studio thinks my form is in the Databse folder,
but it isn't, it is in the Project Folder.
Someone suggested making sure my output path as /bin, mine says bin/, and
when I tried to change it to /bin, VS.NET turned it back to bin/
Anyone know how to fix this?
Also, another similar problem creeps up when I import names from an Excel
sheet, say the Excel sheet is in the C:\ root, I'll get an error that says
my path to my .mdb is invalid.
In other words it stops looking here
D:\Documents and Settings\j\Desktop\DEVELOPMENT\GradID\Database\GradIdentDB.mdb
and starts looking here
C:\Database\GradIdentDB.mdb
if the Excel sheet is in the D:\ root
then it start looking here for my .MDB.
D:\Database\GradIdentDB.mdb
this makes no sense at all.
Any help would be great.
thanks,
Jason

You are going to need to modify your connection string. This is done most easily by modifying the " Windows Form Designer generated code " - you know, the stuff you're not supposed to change.
1. Search for "ConnectionString" in the hidden text.
2. In that mighty long string, find "Data Source=". This will give you the full absolute path. I think you can just change out the full path to your relative one. Otherwise you can set the path to 'Application.StartupPath & "\Database\GradientDB.mdb"'

Hi, I have a problem with drag and drop: every sample about it i have found shows only how to drag a text from a textbox to another or a listview/treeview item to another. Instead, I have some controls (some shapes) and i need to allow to the user to drag them over the form like the visual studio IDE, with the resizing handles, the drawing of the dragged control's border, etc... exactly how the IDE! Can anyone help me, showing some samples (in vb.net or c#)?

I am writing an automation program which has a form that displays a bunch of values. There is a program (class) which runs in the background and updates the form. I would like to place a button on the form which should pause the program (class) from running until the user says it is OK to continue. Unfortunately by running the code in the background, it no longer recognizes the form. (I click on the button and nothing happens). Does anyone know of an easy way to have the button have control when pressed (take away control from the class?). Thanks for any help!

Hello all!!
I got what I hope to be is a pretty quick question. I have a Table in VB. Let's call it "Friends". In it, I have a field called "IDNumber" that is generated by two other fields "Fname" (first name) and "Lname" (last name). Now I want to be able to simply click a button and have the "IDNumber" field self-generate. Is there a way to set a string equal to a field in the table. I know I can open the table with the DoCmd.OpenTable command.
If anyone could tell me how I could grab the fname and lname field info and store them in a string, that would be cool.
Thanks a lot,
Nick

I have avb6 project with one form. It has a monthview control and button.
In form activate, I setfocus to the monthview control. In the code for the button all i have is 'end'.
If you click on the button when the monthview control has focus, the click event does not fire until you click a second time (not double click). If i dont set focus to the monthview, the click event fires as it should (but offcouse my user hasnt selected a date!).
Anyone know whats happening.
Ive moved to the monthview control from an older calendar control because in xp, visual studio 6 crashes when accessing the old control (only in xp, ok in nt4)
Im new today to this site, many thanks in advance.
