I have a window that needs to run a length process. The process is threaded so it doesn't lock up the screen. However, I need this to run when the window is first loaded, not based on a button click or anything. The problem it creates is that it causes the window to stall a bit when initially painting itself. I even tried to put the call to the method in the Shown event, although it helps, it's still not perfect.

I'm having a problem with the graphics portion of vb.net. As a school assignment, we are making "turtle graphics" applications. I have mine working perfectly, the problem that we are having (not even the teacher can fix it) is that when the window gets sent the command to be painted (ie minimized and maximized) the drawings in the picturebox I am using are completely erased. I am looking for a way to prevent this from happening. I have been trying to store the image as a bitmap in memory, which does not work. Is there another way to draw to a bitmap/image in memory and then output that to a picturebox?

I have a rectangle that I dynamically draw in a Window. Said Window has a background with it's opacity set to 0.4. I'd like to make the area inside the rectangle completely transparent (see what's behind the window).
Here is the code of my Window :
<Window x:Class="TakeAScreenzone"
xmlns="[URL]"
xmlns:x="[URL]"
Title="PloofTAS" Height="355" Width="539" Topmost="True"

What I want to make the OpenTK window to be completly independent from whatever is going on with the other controls (for instance if button_click is Thread.sleep(10000) I dont want that my animation freezes for 10s). I want to have it in its own thread (no BackgroundWorker). The problem is I dont know what modifications should I do to get it working. It is currently initialized in InitializeComponent section. I want that all events and everything is handeled in its own thread, basically 2 "programs" in 1 form.

View 13 Repliesi want to make a paint sort of program and so i have read about how to add controls at runtime. but i cant figure out how to change the properties of the control... for ex, if i add a line( that is the user clicks the line tool on the toolbar) he should be able to place it anywhere on the area available, and after that also if later he wishes to select it and resize/change color etc. it can be done.
View 4 RepliesWhilst playing around with DataGridViews in VS I've accumalated quite a few TestDataSets within my project.
Can someone please tell me the correct way of removing these cleanly? At the moment I've been Right Clicking a DataSet (from within Solution Explorer) and either clicking 'Delete' or 'Exclude From Project'
Doing this throws up Errors in the Error list such as;
TestDataSet is not defined
TestDataSetTableAdapters is not defined
TestDataSet is not defined
TestDatasetTableAdapters is not defined
I then double click each error in turn which takes me to the actual code with the error and delete this.
I have quite a lot of TestDataSets and I'm hoping there is another way to do this much cleaner.

View 1 Repliesthe application I am developing does not exit completely. i.e. the process can be seen in the Task manager. This happens only when I click on the [X] button on the title bar of the window of my MDI form. If I use the File >> Exit in the menu of my application, it exits without leaving any traces. I have used the "End" method there. But the process stays when I click the [X] on the control box on the title bar.
View 6 RepliesIs there a command that closes an application completey down, including any hidden forms, etc?
View 3 RepliesI have a form that I use to get the user to input such as a username and password in order to make a network connection. This connection can be disconnected and reconnected as many times as neccessary whilst the application continues to run.
I obviously, therefore, need the form's text boxes, combo boxes etc to reset to their blank versions every time that the form is shown.
In VB6 this was easy; you just unload the form which completely removed the form from memory and thus the next time you showed it it was reset to it's blank state. In VB 2005, however, there is no unload so we have to use Close. I have done this and assumed that it would function in the same was that unload did in VB6.
The problem is that when I close the form using the form.close event handler the form disappears perfectly but when the form.show/showdialog is used the old form data still remains telling me that the form hasn't actually been unloaded but rather appears to have just been hidden.
I'm using VS2010, SQL2008 and using asp.net vb.I have a couple tables, Project and Projectstatus - looking something like this.
project
- ProjectID (autoincrement)
- ProjectName varchar50
- Projectoverview varchar200
[code]....
What id like to happen is that when i create a new project (into the project table), that a row is created in the projectstatus table, inserting the projectID from the project status for reference.I don't think this can be done from within VS, correct? therefore, do i need to create a SP to perform this action from DB side?
When i dim a variable as a form and then close it ( frm2.close() ) then just the form window will be closed. How can i close the form completely so that everything like a timer will be closed too?

View 12 RepliesI am having an issue with my msgbox calls in vb.net 2010. See attachment. Notice the form icon in the top left of the titlebar. Is there a way to replace this icon with my application's icon? I have my app icon already set through the project properties. Barring that, is there a way to remove the icon completely?

View 7 RepliesI don't know if this is a VB2005 or MS Excel issue so I will start with VB2005.
This is how I open an Excel file in VB2005[code]...
The problem is MS Excel always open a Book1.xlsx in addition to my Data.xlsx. As such closing Data.xlsx only closes Data.xlsx but not Book1.xlsx. Over time, as I continue to develope and debug my program, Task Manager would collect "countless" Book1.xlsx. Wth EXCEL.EXE still opened, I noticed that my VB2005 doesn't work "completely" right.
If this is a VB2005 issue then how do I "completely" close everything that is Excel? If this is a Windows issue, and if you could offer a solution as well
How can I completely stop code execution?
Also, how can I hide a form and keep all information saved so I can bring it back up again?
For instance, I have form1 with "alpha" written in a textbox. Now when I hide form1 (Me.Hide), I would like to be able to bring form1 back with "alpha" still written in the textbox.
Currently, I hide it, and when I show it again, the textbox is empty.
Okay so ive got this project iv been working on. Almost ready to get the beta on its way, last thing I needed to do is retrieve the EXE and change its icon. I found the EXE in the "bin" folder. Copied it to desktop. I went through the properties, no way to do it. Then I searched youtube, and google. Only possible way to change it I found was to use softwares. I tried Resource Hacker (ive used years back, this program was handy), but it didnt work. I replaced the default window-looking box icon with my icon, and that seemed fine. But once I saved and exit, the new file with updated icon was supposed to be created. Well it was, except just looking at the file icon I knew it didnt work. But when I right click and go to properties, that one changed. So why dosnt the MAIN icon change? In RH I seen no other icons
