I'm primarily a C# developer and in C# you inherit (or implement) an interface. So, yes, you implement the interface in the class.
cstrader232 wrote: But I can't do that because the class does not exist in my dynamically created .dll
Sorry, I though it was the class in the DLL that was inheriting (implementing) the interface.
If it is in the main exe, then shouldn't the class already be instantiated? (You might want to show some pseudo code so I understand what you are trying to do)
cstrader232 wrote: I thought that the interface .dll would allow my plugin .dll to find the class from the main .exe at runtime. I still don't see how to do that.
I think you are going the wrong way around. It should help the code in your EXE use the dyanmically created class in the dynamically loaded DLL.
Anyway, some pseudo code of what you are trying to achieve (with or without interfaces) would be most beneficial at this point.

I am using VBA 6.3 and MS Access 2003.
I have a combobox set from a RowSource (a query on a table).
The bound column is a hidden column, width 0"
How do I set the selection for the combobox via vba code, e.g. set it to first, last or say 3rd item in the query?

The following will work
1) Make sure that the bound column is the first column
2) Make sure the first column is the only visible column
3) Use combo1 = "text" to set the text content of the combo
4) If you have a combo changed event handler then explicitly call it, the assignment in (3) doesn't seem to be sufficient to invoke the handler.
I've not tested
a) having multiple non-visible columns
b) having the bound column be non-visible
This may not be the most general solution but it works for my situation.

Also I had to explicitly set the focus to the combobox before assigning the text,e.g.
form1.combo1.SetFocus

I've got an MSHFlexGrid on a form and it is set up to not highlight cells or rows when the user clicks. Howver, I've put code behind the click event to check the background color of the cell in which the user clicked. If it is not yellow, I set the background color of all cells in the row to yellow. If it is yellow (i.e., selected) I set the background color back to white.
What I want to do is to allow the user to select multiple rows by holding the shift key down while they click but this doesn't seem to be working. When the shift key is held down during the click event, the row that is selected appears to be the same row that was selected when the first cell was clicked in rather than the actual row in which the mouse click event occurred. Does anyone know how I can get tis to work the way I described?

I finally figured out my problem. I was looking at the .row property instead of the .rowSel property. Once I figured this out the rest was relatively easy.

In toolbox there is printdialog options. Simply drag it and drop it onto form and then you will able to use it inside your code. For example I want to open a print dialog when user clicks a button.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
PrintDialog1.ShowDialog()
End Sub
However, there are more things to do for printing for example you should bind the content for a specific document.
I hope that helps

I recently posted up an article here[^] with a control to do just that - worth a try...

Is there a specific version of VS 2005 or add on to get this interop service?

You might want to look at this[^] page for more information on the Office PIA's. There's more info on installing them here[^].

In my software when I'm in a textbox(multilined) and press Ctrl+T a text box must appear beside the cursor(no matter where the cursor is).
pls Help very urgent.
|
|
|
|

You can get the cursor position ON YOUR FORM using something like:
Dim cursorPosition As Point = Me.PointToClient(System.Windows.Forms.Cursor.Position)
Put this code in your form's key handler code and it'll give you the coordinates of the mouse on the form, not the entire screen.

To preface, I have only taken on VB.net course and principles to programing, so I am a newbe to all of this.
To the question. I have stated creating a program that will allow me to centrally administer all of the workstations on the network...(ie. WOL, Reboot, Shutdown, execute *.vbs....)
I have figured out how to open the excel with all of the data needed, but how can I now select the data from the cell(say MACAddr) and execute a *.vbs on it.
If CompName_selected
then read excel and find CompName_selected MACAddr
execute command (ie "shutdown /t" or "*.vbs")
loop until all CompName_selected complete.
end
Any help would be greatly appreciated

You would use the Process[^] class for this. Usually, something like this:
Dim newProc As Process = Process.Start("shutdown /t")
or
Dim newProc As Process = Process.Start("myscript.vbs")

like
dim days as integar
days = Date.Now.ToShortDateString - any date.ToShortDateString
Ahmed El-Badry
|
|
|
|
|
days = (DateTime.Now - anyDate).Days;
If you substract one DateTime object (NOT string) from another DateTime object you get a TimeSpan object. TimeSpan has the property Days which appears to be what you want.

Please give an example of it

Parameter means that id which has primary and foreign key relationship.
But I don't know the code how to pass the parameters.
and parameters should be passed at both ends (I mean in the crystal reports as well as on the coding side)??
I don't want to generate the window that ask me which id u want to select .
Please help.

I am working at VU meter at the moment. That is, grabbing the microphone volume and show it in progress bar. Should I use winmm.dll for it in vb.net? I understand that I am able to use this module to get output volume but how I should get input volume?
Thanks in advance.

Hi Viewer!
I have a webpage containing a form having a listbox and some buttons. I am faicing the two problems. The first one is that I am facing problem in selecting an item in a listbox form visual basic applicaton.
The second one is that there are several buttons on it having same name. So how can I click on my required button from VB application because there is a confusion that from what name I should call my required button.
Consider it as a CHALLENGE for you...
I have written this because lots of experts are already failed to solve this problem.

Post a snippet of your code and can you explain the complete details of your problem, may be this is the reason why lots of experts are failed to solve your problem.
Help us to understand your real problem and probably I or somebody can solve your problem.
Regards,
Mark
