I have a form which contains a tab control with three tabs on it. On a second tab there is a PictureBox. The problem is I can't figure out how to check if the PictureBox is completely loaded.I can't put "pictureBox.CreateGraphics.DrawRectangle(Pens.Aqua, 100, 100, 100, 100)" into a form load event because picturebox is not active until I click on the tab2. It neither works with tab2.enter event nor any other events I have tried so far. However it works through the button.click event and it works briefly with the picturebox.paint event before its wiped out. So I presume it will work with a timer event as well.But the question is how to to make it work without a button or a timer?
View 3 RepliesDuring my program I put lines out to a text box on the screen as a form of logs.After each line is added I do a ScrollToCaret() to move to the end of the lines.However, if I'm manually scrolling around the logs/lines (eg: using the scroll bar) I don't want to that.
Is there something I can check so as not it issue the ScrollToCaret() if the user if currently scrolling around in the text box?
the 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 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 6 RepliesI have a program with the line process.start("shutdown", "-s -f -t 00") However, when it's executed, everything exits, and the logging off text appears, then the screen blackens out and there's only the mouse pointer. Nothing can be done like opening the task manager, I just have to shut it down using the main button, holding it for 7 sec.
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? I've seen of VB.net msgboxs don't have an icon, so I'm not sure how it got there in the first place.

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

View 4 RepliesI'm running a multithreaded application that connects to a database, the connections are closed when I'm done with them (and I dispose of all the threads). I've tried clearing the connection pools, setting pooling=false and I've used both .dispose and .close.
I get the error "cannot drop the database X because it is currently in use" if I try to drop the database I connected to after the connections have all been closed.
Below is my code:
Dim comExecuteInsert As New SqlCommand
Dim comm As New SqlConnection
If (Not comm Is Nothing) Then

The stored procedure creates temporary tables which it later drops and inserts data into tables existing in the database.

View 13 RepliesI 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.

How do I make the application wait for the WebBrowser to completely load a page before it proceeds.
View 4 RepliesI have a WebBrowser Control in my VB.NET application. Now the it browses through many URLs (may be 10 - 20) and I want that each of the page HTML saved in text file. Now the thing is that when I write the HTML of page in file, it does not write the HTML of current page rather than the initial one because it calls the event before even the page is loaded.
How can I wait until the page is completely loaded before calling any event?
