Could you please be more specific. I'm not that good with APIs, and I have never done this before. Thanks.

actually its very simple to do
just open the api viewer (either thru addin menu in the ide or from program group (tools)
then load file win32api.txt in the api viewer (file->open)
add declaration for FlashWindow in ur code
another alternate way is to search for file WIn32api.txt (in visual studio folder\common tools) and copy decl of the function in ur code
now all u have to do is to just call the function FlashWindow anywhere in ur code and see ur window flashing once
put the first param as ->
and 2'nd param is to specify whether window inverts its state after flasing or not (See MSDN)
if u want to flash n times then
add FlashWindowEx function along with FLASHWINFO struct in same way as i told u
i hope now u can make it work
enjoy

I'm having problems with my VB ole control. I inserted the (wordpad) object inside the form, and added the code doverb to display it at run time, but the menu items are not displayed. If i run the program with doverb and use double click on the control the menu is displayed. Any ideas.
Thanks

I've created a windows service using VB.NET, the service monitors the users actions and should lanuch an application if particular set of conditions have been meet. The problem I'm having is the launch of the windows application from the service. I found an explaination to my problem in MSDN "Process created by the service cannot display a user Interface". I think if I start a new process/thread as the current user not the service I should be able to start my application. My problem...How do you create a new process/thread as the current user?
If anyone has a solution or idea I would greatly appreciate it. Thanks

I used to use control array in vb which is currently not support by vb .net. For example, if i have 5 text box and make it as control array of text(0), text(1)...text(4) to refer to respective text control. what happen is i have a problem of refering to the control in the form when the control having the focus by press the f3 key to call the lookup windows...in vb .net. Attached with sample code for your reference and understanding in VB.
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
With ActiveControl
Select Case KeyCode
Case vbKeyF3
Select Case .Name
Case "text"
Select Case .Index
Case cozsys_textbox0
If Lookup("select zsys_comid as Company_ID, " & _
"zsys_comnm as Company_Name, " & _
"zsys_regno as Register_No " & _
"from zsys order by zsys_comid") Then
.Text = LookupFields("Company_ID")
Case cozsys_textbox1
Case cozsys_textbox2
Case cozsys_textbox3
End If
End Select
text(.Index).SetFocus
text(.Index).DataChanged = False
End Select
End Select
End With
End Sub
where cozsys_textbox0, cozsys_textbox1, cozsys_textbox2, cozsys_textbox3 is the array index for text box 1 to 4
How could we refer the control array in the calling Private Sub form1_KeyDown(ByVal eventSender As System.Object, ByVal eventArgs As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown in vb .net. Please help me ? Any other methods ?
Thank you very much

HI,
Is there a way I can use the windows "file moving" animation that explorer moves?
I have a program that takes a file/directory, does some hashing stuff etc etc and then moves the files to a new directory, and performs the same hashing algorhythms to nathermatically prove files did not change between locations...
I want the "file moving" animation to pop up while I am doing it....
can it be done, or do I have to build my own??
Thanx

Is it possible to freeze columns in the MSHFlexGrid control? If not, is there another control that can be used in VB6 in which columns can be frozen in the same way that Freeze Panes works in MS Excel?

Dear Sirs,
I develop a mediaplayer (mPlayer.exe), which uses the runtime argument to pass in the file name that refers to the movie to be played back in the player.
Instead of entering the file name each time when I run the mPlayer.exe, is there any way I can develop a wrapper, which will make use of the mPlayer.exe and the file name as input and generate a new mediaplayer inside which the file name had been hardcoded. Thus a stand alone executable could be run instead of a mPlayer.exe and a file name.
I tried to do like this because only the new wrapper and the excutable mediaplayer (mPlayer.exe) could be released under my current development plan.
Thanks

I have a component(dll) which is registered on COM+.The dll has only one add
method and return a value.Now i want to access this component from another
machine.I am wrote the code in VB as activex exe which i have checked option
for remote server files also.
i just want to know how to access this dll from anyother machine.What are
the steps involve in that process.

on the machine where you have installed the component in COM+, go to the application, and choose Export. Then select Application Proxy.
This will setup the right informaiton, and create an MSI installed file.
Now go to the machine where you want to use the component, and run this MSI.
YOu will now be creating the instance of the component on your com+ server.

Hi,
I have a dataset that is ordered by an account number. But I also want to access this dataset by last name. When I setup my combo box with last name, I can move around the dataset but the names are not in order. I've setup another dataset where the SQL pulls in name order. Does anyone have some code I can use as an example to move my main dataset around using my sorted name combo box? Thanks in advance.
Thanks,
Mike

I'm trying to write a small program that shovels search parameters into Kazaa and then initiates a search. Almost a dynamic macro 
I'm fairly new with Visual Basic and C++, and I while I understand basic DLL structure, I am confused as how I can control one program through another.
Any thoughts or ideas? I know I'm missing something.

I am viewing a multi page document (.Tif) in a picture box. I have no problem paging back and forth thru the frames until I rotate one of them. After Rotation of one of the frames the picturebox refuses to display the selected frame. It still pages thru the frames and it dose refresh, but the selected frame is not displayed. Dose anyone have an answer to this problem?

I have a problem with GUI design and would be interested what anyone else would do.
My client wants their users to be able to change the system time to another date other than NOW(). What they have requested is a checkbox be placed on a form and when ticked a dialog pops up with a date-time pick on it from which the user can select the new system date. I have presently put OK and CANCEl buttons on the said dialog. If the user has changed the date to other than NOW() and hits OK then the system date is updated, otherwise clicking on CANCEL leave the system date un-changed. If the system date remains as NOW() the check-box is then un-ticked otherwise it is ticked.
The problem I have is that if the system date is already something other than NOW() and they wish to change the date to some other date but still not NOW(), clicking on the check-nox obviously un-ticks the checkbox and desn't then show the said dialog they have to tick the checkbox a second time to get the dialog to show.
I think the checkbox isn't quite the correct widget to use. They don't want the date to be visible until the dialog is displayed.
Any advice would be appreciated.

I think so you are having a problem,
As per the problem i understand is When you open the dialog box to display and store it in a variable the system time and date is stored.
But when the user selects Ok button or cancel button the time gets changed.
When you next call now function.
it is better to use date function and time function
this will give you the current time and todays date.
Thanks!
