So I have a few variables in an array a I want to compare another variable to each of them, if it is the same do something, AND STOP THE FOR LOOP. else carry on the for loop. So...
for i = 0 to 4
if variable = a(i) then
do some stuff
[code]....
how do i end the for loop from within an if statement that is in the for loop
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

What is the correct syntax to go to the next sequence in a loop if certain conditions are met bypassing the contents.
I am using goto and inserting a line number which is probably not the best way.
I.E. My syntax:
For i = 0 to 100
If i = myvariable goto 100

I have a list of string in an array. I'm loop through those strings and if the text of a combo box matches one of those strings, I want a message to appear. If they don't match, I want a method to be executed.
[CODE...]
The messagebox appears, but the method is still executed. Which means it isn't stopping when it finds the match. I tried exiting the loop, but it still doesn't work.
I'm using a loop condition to check if there is null value in the columns, then remove it.

For i As Integer = counter To dt1.Columns.Count - 1
For x As Integer = 0 To dt1.Rows.Count - 1
if some condition then
something = true
[Code]...
Sometimes it runs correctly and sometimes even though when i becomes greater than (dt.columns.count - 1), it still executes the for loop and throws an error that there is no column with that index. I must be missing something here but I'm not able to debug the issue.
My application uses 12 checkboxes. Dependant on the status (checked or unchecked) different action are required. I can't seem to be able to structure a for next loop to do this.

When a user leaves a TextBox on the form I execute a format and save to a variable. This is saved to a database by clicking on a ToolStrip button.
The problem occurs if the user moves the mouse directly from the TextBox to the Button. Neither the Leave event or the Lost Focus event is triggered, the variable is not created and, of course not saved.
If I put the code in the Save Button and the User moves to another control, the formatting(data type Double to currency format in the TextBox) that I want to show is not executed.

I have a modal pop up that is supposed to upload documents. It does that just fine, except that it doesn't give them a title, therefore nothing shows up on my page since Title is how they show up in the list.

This is in ASP.net 4.0 VB using Microsoft SQL Server.[code]
View 1 RepliesI find that if I do me.close and then reopen the form with showDialog later, things are as they were before I closed it. If I use me.dispose and then later open the form again, its as if it was never opened before. Are these two both valid methods for leaving a form?

I'm trying to update an old code that I don't have the source code for. In this code, the user enters an integer in a textbox as part of a form. Once they move to the next textbox a new form opens to input the number of files that the user chose (in the textbox).I have created all of the forms, but I can't figure out how to get the code to open the new form once the integer has been entered in the textbox and the cursor has moved to the next textbox. I would prefer this to happen automatically and not involve a button.
View 13 RepliesI am experiencing a strange issue with a VB6 -> VB.Net conversion. There is a function that uses ADOX to look through the tables in a given database, and reset the seed values of any columns in said tables with the auto increment property set to true.I tracked the issue down to a call of "col.Properties("Autoincrement").Value". If this line of code is commented out, then the file handle properly terminates when I close both the ADO and the ADOX connections at the end of the function. If I leave that line in, the handle stays open despite the closing calls and forcing garbage collection.Here's how I am closing the objects:
System.Runtime.InteropServices.Marshal.ReleaseComObject(adoConn)
Dim connection As ADODB.Connection = cat.ActiveConnection
If Not connection Is Nothing Then

I'm looking for a way to process the text entered into a textbox, before the the focus is lost from the control. Or a way to pass a reference to the control to a function/sub when the control has lost focus. In Access I would be able to use the AfterUpdate event. I have tried the following events, but have not figured out how to get what I want from either of these events:
- TextChanged (tried to capture the Tab key, didn't work)
- Validating (when fired for Text1, the ActiveControl name is Text2 which is the next TextBox control)
I have a situation like this:
if <some test> then
do lots of stuff
endif
I'm refactoring the code getting ready for some major work. I want to remove the if/endif pair but leave the contents (do lots of stuff) intact and in place.
In Visual Studio 2008, what is the easiest way to do that without making a mess
I have a DGV with a CB column in VS2008. I would like an event when a DGVCB selection is made (without leaving the cell). It will probably have to be a DGV cell or row event but I can't find one that fires as soon as a DGVCB selection is made.
View 3 Repliesi am having trouble getting this to parse and remove the html and only leave the flash applet here is my code so far:
WebBrowser1.Document.Body.InnerHtml = WebBrowser1.Document.All.Item("object").OuterHtml
Our program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.

Need help removing a copy of my program shown on the Task Manager after I close.
I must kill a conflicting program that cannot share the COM port and then reinstate when myprogram ends. To reinstate I use: System.Diagnostics.Process.Start(conflictingPath & conflictingProgram)
In the last line of my Form1.Closed I try to end all with:System.Windows.Forms.Application.Exit()
Not working - each time I run this program it does kill the conflicting program, can do its dialing function and upon closing reinstates the conflicting program. But each time another copy shows under Task Manager.
I've been working on a GUI in WPF which I'm fairly new to, having only used Windows Forms up until now. So far, my GUI is very simple: it contains two rectangles, each of which drops a shadow. The shadow creates an effect of rectangles "floating above the canvas" so to speak.
When one of the rectangles is pressed, the myRectangle.MouseDown event is handled such that the shadow goes away, thus creating an effect of the rectangle being pressed down onto the canvas, like a button.Similarly, when mouse button is released, the myRectangle.MouseDown event is handled such that the shadow reappears and the rectangle "floats" again. This behavior make them resemble buttons. Note, there a reasons I want them to be rectangles and not custom buttons.
[Code]...
If the pointer leaves a rectangle while mouse button is pressed, I'd like shadow to reappear. This is arguable simple, because theoretically in this case, any time myRectangle.MouseLeave is raised, the shadow should come back on, even if it was already there.If the pointer left a rectangle when mouse button was pressed, then came back while before the button was released, I want the shadow to disappear again. This one is what gives me problems. No idea how to do this.
I am attempting to write a program that will disable the Local Area Connection while leaving the Wireless connection enabled.
