for folders you can folow a simular way only you need to use getdirectories and createdirectory
see code below

For Each myFile As String In IO.Directory.GetDirectories("C:\temp")
    Dim filepath As String = myFile.Substring(myFile.LastIndexOf("\"))
    IO.Directory.CreateDirectory("c:\temp2" & filepath)
Next myFile

MDI form closing

I have a case on an MDI form where there may be unsaved data and Im trying to allow the user to cancel the close process instead of just a Yes No answer.

Is there a way for me to know that the MDI form closed or didnt close?

Handle the FormClosing event. You can ask the user whatever question you like and set the e.Cancel = True to stop the form from closing.

Yes I do that but I also do some other activities in the Main Form and they seem to be done regardless of what happens in the form closing of the MDI.

How are you handling the events in the main form? Are you responding to the FormClosing Event if so you should be monitoring the FormClosed Event. Besides guessing, I don't have enough information to help solve the problem.

The main form does a Me.ActiveMDIForm.Close.

I am assuming you have code that executes after the close call and you want to prevent this code from executing. I believe you have 2 options:

1. You can count the number of Mdi child forms that are being displayed before and after you call to AcitveMDIChild.Close. If the count changes you know the form closed otehrwise something has prevented to from closing.

2. Move all the code after the call to Me.ActiveMdiForm.Close to a different function that handles an event from the MDIChild when the form actually closes.

Hope that helps.

User resizing of column in datagrid

Is there a property to allow the last column in a datagrid to be dragged, and hence expanded, past the bounds of the datagrid?

The issue is that the user has to double click the last column to resize it past the bounds of the datagrid.

I would like the column resizing to work in the same manner as windows explorer.

I have googled but to no avail.

Any help appreciated.

This is never going to work. SQL is a different language to VB, your code needs to build valid SQL, the database cannot tell that these are variables within your VB code. So, your best bet is to write a stored proc, but if you want quick and dirty, just concatenate a string which includes the values of the dates in those controls/variables, instead of the names.

How can I convert the keyboard layout to arabic? I could covert the characters using the API 'LoadKeyboardLayout'. But the digits are not converting to arabic. I searched in the net for the API I understand the digits can convert with the function 'SetLocaleInfo'. This function receives 3 arguments but i don't know the value should be passed to this funtions. Please help to find the values of the arguments.

Thanks and Regards,

Transparent layer/control..

DalePurdon13-Aug-07 1:43

Hi there

(vb.net)

I need to add drag/drop functionality to the webbrowser control. In vb6 it exposes a DragDrop event, it seems MS has made it redundant. I am now looking for another way to do this....by placing a transparent panel/usercontrol over the webbrowser control, and capture the drapdrop event in the panel. I have tried using a picture box, panel, as well as blank usercontrol with background set to Transparent, and I cannot get it to be transparent as run time.

1. Anyone know how I could implement a dragdrop event on the webbrowser control in vb.net?

2. If the above is not possible, how do I make a panel (or usercontrol) transparent?

Thank you
Regards
Dale

I don't think making a panel or uc transparent will work
if you put them transparent the events of the control will probably no longer fire (I'm not sure about it dough)
for drag and drop there are normally property's on the form and on the control for that:
allowdrop
and events:
dragdrop
dragenter
dragleave
dragover
I suggest u look at these
If you don't find it I have some code that does this but not with me at the moment (I'm at work) and I'm not sure I'll find it again (been a while since I wrote it back in my school days)

Transparent is not transparent. I know, just bear with me.

When you tell the BackColor of a control to be transparent, you're not telling the control to be transparent. You're actually telling it to take on the background properties of the controls parent container, in your case, the background of the form. That's why, by default, the background of the control turns gray, not "see through". This is why you can't see other controls between the form and the "transparent" control.

There's no way to "force" this to work using any property. You'd have to make your own version of the control you want to be "transparent" and render it, ALL OF IT, yourself. You'd have to provide all the drawing code to draw the entire control!

This also introduces a problem. Since in order to get an updated view of the "background" of your transparnet control, all the other controls under your will have to redraw themselves. This results in a performance problem because your redrawing just about the entire form to redraw your control.

Dear All,
I am using server/Client application which will communicate through winsock Control. Coding for all the database transactions done in the server application. Only the data is passed to Client. For each transaction client will request the Server to do the transaction.

Here my problem is between the transaction if Database is down/Network is down I am getting "End of communication channel/Oracle not available/TNS-packet failure" errors. I am using ADO connectivity for database transactions.

I tried by checking the socket.state, On Error goto. But nothing seems to be helpful. Any suggetions/Solutions are welcome

Thanks in advance

RTF files manipulation without using builtin controls

In our project we have rich text format (RTF) report template files with bookmark fields.

what we required is to read that file in background replace templates bookmark fields with DB field values (may be in iteration) and save this report file as .rtf but without using any rich* controls....

basically we are looking for a library or api already doing the same thing ... (since we follow the rule ... NEVER RE-INVENT THE WHEEL)

we also do not want to use MS word automation. since it has some issues...

Any help would be appreciated... either by code example or by guided links on net

thanks in advance
