View 3 RepliesIs there a way to write a single function that will control validating the input to any textbox? How to pass control of it.
E.g.: My second try was to:
Dim CurrentTextBox As TextBox << Declare a global
Write a function that uses the global textbox and takes in 2 parameters, one determining the length it has to validate and the second telling it what to do once the input is verified
Public Sub ConfirmInput(length As Integer, which As Integer)
If (CurrentTextBox.TextLength < length) Then
CurrentTextBox.BackColor = vbRed
GoTo DONE
ElseIf (CurrentTextBox.TextLength > length) Then
CurrentTextBox.BackColor = vbRed
[Code] .....
My first try was to pass a textBox parameter to the ConfirmInput function but I believe that's the same problem as above.

View 3 RepliesI've recently been working on a simple media player (following some guide and using my small brain ). I have created a simple playlist, with load/ save ability, add remove track and play and all the normal bull . However I was wondering if I could get some help making it more advanced: How do I create my own track / volume sliders - and even a custom 'screen' to play visualisations / movies? how do I create skip buttons (the ones on the media player controller don't work :@)? I know how to make a button skip a track (I think), but how to I make it skip to the next track in my playlist box? [code] I have created a context menu for my playlist, with buttons such as play, add and remove, but I want it so that when I right click on song the code activates on the song I right clicked on. At the minute whatever song I right click on it still runs the code on the song that selected not the one I right clicked on.Also my playlist, displays the whole file location of the tracks, how to I make it display only the tracks name.Also I have an open dialog control, I know how to set a filter, but how do i set it to filter more than one extension.please note that most of this code is from various guises, and I have simply edited it and merged different codes to suit my needs.

I am writing an app that puts multiple controls on a form at run time and then I edit the controls in a property grid. All that is working fine. I'd like to 'mark' the contol when it is 'selected just like visual studio does with the dotted border (or soemthing similar, I don't care that it is just like vs). I'm already using MouseDown event to grab the control and send it to the PropertyGrid, but I have now wired it up to take multiple controls and need to 'identify' them on the screen.

View 2 RepliesI wonder how you can make a picturebox selectable at runtime and also change the size and location during runtime?
Well I know how i can change the location of a picture box during runtime but that is only with a picturebox that is already defined in the form before runtime.
So I write an event for that particular Picturebox.
But now i want to do the same thing with a picturebox that a user can add during runtime and then the user should be able to select and move the picturebox.
So now i can't add code to the picturebox event so I wonder how you should do this. ( Maybe with reflection?)
And what if the user added 10 picture boxes and selects a certain picturebox. How do you make it possible that the picturebox the user clicks on is selected?
Should you store each picture box location on the Panel and then when the user clicks on a certain pixel in the panel where a certain picture box is it get's selected?

At design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime.

How does MS do this in the IDE?

So I wrote a VB.net project in Visual studio.I have a scheduled task that is set to run the program every morning at 10AM. If I use windows explorer and double click the application, it runs fine.If I open task scheduler, open the task properties, and browse to the application, then choose run, the program fails, due to Runtime exceptions.I know I have the path entered correctly, since I can debug the instance when it crashes from the task scheduler. VS2010 pulls up my source code.The exception is System.IO.FileNotFoundException, remember, it works fine when I double click the app. If attach a debugger to the process after it is executed from the task scheduler, I can then restart the debugger, and Voila!, The application runs fine.

but it maximizes to the screen size. how to control the maximize screen button? I don't want to change the formborder style setting from sizeable because I like the way it looks like this. I just want to get the min max buttons to go to sizes that I want them to go to.
another thing is there a way to save the size of the app that the user has it set to before they send it to taskbar then when the user brings it off the taskbar is there a way to bring it back to that size?
