I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:
System.IO.Path.GetExtension()
System.IO.Path.GetFileName()
System.IO.Path.GetFileNameWithoutExtension()

on Form1, i have a combobox1 where i have 15 values. im using a case statement with those 15 values to decide what is the next form to go to. i need to make sure the user cannot add in his own text to it or click the NEXT button without having any value at all. how do i add these "exceptions" to my code?
i would think any exception would go before the case so that it could tell you didnt put in the right answer before it looks through the case statment and give you a nullexceptionhandler reference.
How can i make the font's size in richtextbox equal to combobox1?
RichTextBox1.font.size = combobox1.text
not working
I am really baffled and can't work out why this is happening. I have this code with transfers text from a textbox and adds it to combox items. My problem is that after the combox has got 2 items init, anymore you add there will be muliple of them and not just one for example:
[Code]...
[Code]...
1. Add Combobox1 to a form and add the above code
2. Run the form
3. Enter some text not in the drop down list or leave the combobox text blank
4. Click the form close button ( the "X" )
5. The error will be displayed, "ERROR - Invalid Entry!"
6. Press OK on the messagebox
This is where something goes wrong. If you click the Dropdown arrow of the combobox, the dropdown list wont stay open. ( unless you hold the mouse button down ). This doesn't happen if you click or tab to another control (like a text box). Then after the messagebox is displayed the ComboBox still works fine.
