Using the Colour Dialog
You can use the set colour dialog to allow the user to select a system color. Below are the most common parameters you will need to set before displaying the Open Dialog Box.
| Parameter | Changes... |
| DialogTitle | the Title displayed in the Dialog Box |
| Color | the selected color |
| Flags | custom settings such as disable custom color button. |
| CancelError | whether an error occurs when the dialog box is cancelled. |
The following code displays a colour dialog. When the user clicks OK, it sets the forms background colour to the one selected.
' Sets the Dialog Title to Save File
CommonDialog1.DialogTitle = "Select Colour"
CommonDialog1.CancelError = True
' Set flags - enabled the Custom Color button
CommonDialog1.Flags = cdlCCFullOpen
' Enables error handling to catch cancel error
On Error Resume Next
' display the set colour dialog box
CommonDialog1.ShowColor
If Err Then
' This code runs if the dialog was cancelled
Msgbox "Dialog Cancelled"
Exit Sub
End If
' Sets Form1 background color to the selected colour
Form1.Backcolor = CommonDialog1.Color

True multithread VB source code controls

I know what you're thinking about. I have exactly the same problem. I don't know how to make Common Dialog Box show such window: http://img230.imageshack.us/img230/7206/selectdirectorytt2.jpg
Dear Sir
Thanks for you help and I like you way that you got it, but my questation is Can I use Common Dialog without use File Type? because I need only open folder without select file "Only Folder Path"
Using the FileName (path) and FileTitle (filename) properties of the dialog control,
Dim FilePathOnly As String
FilePathOnly = Left(FileName, Len(FileName) - Len(FileTitle))
'or
FilePathOnly = Left(FileName, InStrRev(FileName, "\"))
'or if you use a scripting runtime
Dim fso As FileSystemObject
FilePathOnly = fso.GetPath(FileName)
OpenFileWName = TreeView1.SelectedItem
If OpenFileWName = OpenPath Then
MsgBox "You can not select a directory. Please select a template file."
Else
frmMain.RichTextBox1.LoadFile OpenPath + OpenWFileName
'Unload Me
End If
And it should be as simple as that
Any idea on my problem? I posted it on here as darkwolf
is there a way of getting just the path of the file this way, without the file name in it?
E.G. if i open
C:\Windows\Wini.ini
can i get the program to read just
C:\Windows
from that?
Thanks.
I have decided to do it a different way though. I am now using a Tree view to list all files in the directory. It allows a much better interface for what I am trying to accomplish.
I do have a new problem though. The main function of the form (frmNewTemplate) is to open a file an put the contents into a rich textbox on the main form (frmMain) but it doesn't seem to be working. If I put a RichTextBox on the frmNewTemplate it is able to open the file and put it into the RichTextBox correctly but when I change it to be placed into the frmMain it doesn't update the RichTextBox.
Do have any ideas on how to pass the information from frmNewTemplate to frmMain?
I have included the code below. Again it works until the part of updating frmMain.
OpenPath = App.Path & "\templates\"
OpenFileWName = TreeView1.SelectedItem
If OpenFileWName = OpenPath Then
MsgBox "You can not select a directory. Please select a template file."
Else
Open OpenPath & OpenFileWName For Input As #1
Do Until EOF(1)
Line Input #1, lineoftext$
If frmMain.RichTextBox1.Text = "" Then
alltext$ = lineoftext$
Else
alltext$ = alltext$ & vbCrLf & lineoftext$
End If
frmMain.RichTextBox1.Text = alltext$
Loop
Close #1
'Unload Me
End If
Thank you in advance for any help that you or anyone else may provide.

if you are using the common dialog control in your app then you can set the initdir property to the folder you want the dialog to default to.
I think you may need to check the file selected to ensure that it was chosen from the path that your trying to restrict to.
Is there a way to make it display files in a preselected directory? In a program I am making I would like for people to only open a file in a certain directory. I do not want the common dialog to default to their desktop but to a folder in the applications folder.
Thank you,
Joel Strellner
