VS 2010 Diagonal Line On Program?
Aug 27, 2011
I am making a Tic-Tac-Toe prgram on VB and I have run into a problem. I need a diagonal line on the design that goes over some of the labels if a player wins. I have researched this and cannot find an answer. A picture box does not work because it covers everything up, and when you make a line in the forms it shows up in the background.

is there a way to only allow diagonal resize for a Form (main form)? in other words the width/height ratio should always be kept constant

Is there an "official" way to only allow diagonal resize for a Form (main form)? In other words the width/height ratio should always be kept constant always, no matter how the user tries to resize it

The code in question is in place, and it works. The project is all but wrapping up. That being said, I would love to find a better way to run this section of code in an x64 system so I have the solution ready for future projects. What I currently have in place is as follows:
Function TimeDelay(vDelay)
Dim vTimmer, vTargetTime
vTimmer = TimeValue(Now)
[CODE]...
Now I know the easy way to achieve my goal would be to use the timer object in Visual Studio. The problem I ran into is I was developing an automated command line program. As such there was nothing I could attach the timer to (that I'm aware of). I just needed to pause the program for a few seconds to allow the DTSX package (SSIS file if you're not familiar) to load the file before I remove it from the staging folder.
While I was doing research for this issue I came across the old Sleep() function (referenced to a library in kernel32 as I understand it...never used this before either). When I tried to use this on my current system (64-bit system) I received stack overflow errors. Additional research lead to something called wow64, but I did not have enough time to fully research what this is / how to use it.

I am trying to create a program that downloads audio files via FTP, converts the audio to mp2 if necessary and copies them to a certain directory for consumption by our automation system. (I am a radio station engineer.)I am using the open source converter FFMpeg to convert audio files to mp2. This is a command line exectuted program. Here is the command line that I use to execute the external program with the input and output audio files at the root level: cmd.exe /k ""C:New Folderffmpeg.exe" -i "C:Test.mp3" -y "C:Test.mp2"" This command line works correctly whether I am using Shell() or System.Diagnostics.Process (Process) to execute the external program. I am going the Process route so I can know when the conversion has finished.Now, I really don't want to use the root directory for this but when I go below root with this line using Process the external program will not execute:[code]Can anyone tell me why that line will not work with Process though it works as expected with Shell()? I can't figure out how to stop the external program to get some feedback as to what its problem is.

I have a text file with an unknown number of lines. I want to read this file line by line and send each line's text in a check list box. But how am i gonna do that when i don't know how many lines exist in text the file? [code]The code above reads only the first line. I tried to do it as in vb6 using while not eof(but here i don't know what to write cause my file isn't opened in a certain channel).

the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim FILE_NAME As String = "C:UsersOwnerDocuments est.txt"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim TextLine As String

If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.

40 IF MID$(A$,2,1)=":" THEN C$="SINGLE DIGIT":GOTO 120

I'm a bioinformaticist, I'm trying to teach myself how to develop programs that are easy for everyday users to automate programs used in biological research. I thought VB would be great for helping people be more familiar with bioinformatics. Unfortunately, I'm brand new to VB and am stuck with my first program.
All I want to do is have a window pop up where the user then selects a file from an OpenFileDialog box, and pass the filename to a bioinformatics program names msconvert. What I've been doing keeps giving me a message that seems to says, "Unhandled exception has occurreed in your application. . . . File not found."
However, as you can see in my code (below) I have a MsgBox that shows that the correct file HAS been selected, and I can get the whole thing to run from command line.[code]....
