VB Response.BinaryWrite To Finish In The OutputStream

Jul 29, 2010

I am using Visual Basic to dynamically create a Visio diagram. It is called from a web application. The web app makes the call to the .aspx file, which does its work and then writes the file to the web app through Response.BinaryWrite. The problem is this: there could be multiple users on the web app, and the VB app is currently confusing the web app with simultaneous use. That is, if two users both make a call to the VB app, the VB app doesn't separate the output, so one user gets a binary file (unreadable by Visio) with both users' contents, and the other user gets a blank Visio file. Can I use anything in the Response.AddHeader to distinguish the output so the Java code for the app can pick the correct output?

Waiting For A Thread To Finish?

Mar 11, 2009

I am trying to make a marquee progress bar run while my long function is running. When the function is done running, I want the progress bar to disappear.

[code]...

If I don't do t.Join(), the progress bar disappears right away and then the thread runs. If I do Join(), the progress bar doesn't appear until the message box pops up after the thread is done!How would I get the effect of the progress bar running while the thread is running and then stopping when it's done?

User Interface - standard window/form formatting with correct tab order

Form Must Finish Loading Before The Function Executes?

Apr 6, 2011

I am using Visual Basic 2005. The program I am creating can either bring up a form (with a bunch of buttons, listboxes and a picturebox) and the user can enter file names onto the form OR the user can drag file names from Windows Explorer and drop the names on the program icon to start the program. During the execution of the program, messages are displayed in one of the listboxes.

All this works fine except for part of the drag/drop scenario. When the drag/drop is done, the form is not fully loaded when the code function starts to put out messages. This means the user may not see any of the messages until all is complete. I have tried putting my executable code in the Form1_Shown() and even added a timer to slow things down a little, but nothing seems to work consistently.

VS 2008 Wait For A Cmd Line Program To Finish?

May 18, 2009

I've made a gui for a cmd line program and I need to wait for the cmd line program to finish running before continuing.nd I have some code that starts the cmd line program and then calls a subroutine when it's finished running. But this method won't work since now I'm trying to run the cmd line program in a loop.Edit:Is there a way to just have the runtsmod subroutine (shown below) wait until the cmd line program is finished, instead of relying upon a subroutine starting when the cmd lineprogram finishes. This would simplify things greatly being able to call the sub tha starts the cmd line program and having it finish when the cmd line program is done.

Sub runtsmod()
'If the tsmod program exists in the directory the GUI is run from it is ran
Dim tsmod As String = Application.StartupPath & " smod_GUI.exe"

VS 2008 Wait For File To Finish Downloading

Apr 4, 2010

I'm downloading a file asynchronously so that it doesn't stall the UI. I'm using a very basic WebClient and calling .DownloadFileAsync.The file I'm downloading is required for additional tasks after it has been downloaded. The issue that I'm running into is that, since the file is being downloaded on another thread, execution on the main thread continues while the file hasn't finished downloading.Is there any way to pause execution while the file is being downloaded? Or is there a better method?

VS 2008 : Blocking In DoWork() While Waiting For Another Thread To Finish?

May 6, 2009

In my DoWork() function I register with our sip server. Then I have to wait for a response back. However, the response I get is received in another event. However, before I am able to check the flag in the DoWork() the DoWork() has all ready finished and the response comes after.

I am trying to find a way to wait in the DoWork() until I get a response in the Diagnotic event. I have a global flag that is set in that event that I have to check in the DoWork().I was thinking of maybe blocking in the DoWork() until the other event is finished. Maybe using a join.

' Do work in background worker
'Will return less than 8 if there are no error message from the library
If (Not Me.bgwProcessLogin.CancellationPending) Then
' Register and wait for response

VS 2010 Waiting For A Screen Re-draw To Finish Before Continuing?

I'm writing a simple program that takes a screenshot of tab1 of the GUI, then takes a screenshot of tab2, then tab3, etc. I've got the screenshot code down pat, but the problem with my current code is that it's taking the screenshot of each tab before the screen has a chance to fully redraw, so the resulting images are screwed up.Is there a way to get the program to wait for each tab (and all the controls in it) to be fully visible before each screenshot is taken?I'd like to avoid using a timer for this, as the screen redraw speed will vary depending on the user's computer, and the contents of each tab, etc.[code]
