Hi
I have a MDI form where i want to display a mdi child. but i want this child to behave like 'modal()' so the user can't get out the form when it is not completed correctly.
When i import a dialog in the project and form.show it after pressing a menu item in the mdi parent ... then the dialog is only shown when i minimize the mdi parent.
What's the problem here? :s
And another little thing
I dont' seem to find a method for deleting an entry in a listview.
You guys can help?
Greetings
Jens

Remove listitem:
ListView1.ListItems.Remove(lngI)
As for the form:
The QueryUnload event has a second parameter called
UnloadMode. By testing this mode, the program will know what is causing
the form to unload. Then you can decide what you want to do, etc
These are the constants and a brief explanation:
Select Case UnloadMode
Case vbFormControlMenu
'The "X" button or the "Close" menu
'from the form's System menu.
Case vbFormCode
'The Unload statement is called from code.
Case vbAppWindows
'Windows is shutting down.
Case vbAppTaskManager
'The Task Manager is closing the app.
Case vbFormMDIForm
'The form is an MDI child and the
'MDI form is closing.
Case vbFormOwner
'The form is closing because its
'owner is closing.
End Select

Hi
Thanks for the reply.
About the form i really meant ... When i want to show a form within an MDI parent (the form has property MDI child: false)... Then that form is not shown within the MDI but apart. I want to be able to show the form nice in the MDI parent without making it MDI child. Because i want to be able to 'DoModal()' the form.
I hope you understand my problem :x
Greetings

You can solve this problem programmatically using the mouseover event. When the mouse escapes the form: put it back on the form. As for the form itself, when you move the non MDI form reset the left and top properties to keep the non mdi form within the MDI form. Hope this helps.

Well, i don't move the form myself ... I just show the form that has to be displayed within the MDI parent itself. So it has to behave like an MDI child but it needs to be displayed modally.
I'll explain situation. I have a menu in the MDI parent .. When i click a menu option .. i want a form to display that is not mdi child. So the form is not shown within the mdi child, but minimised.
Because i don't know well what you meant
Greetings

How do lock a file in VB6 without hardcoding to append a .lock ext to the file name?
How do i unlock? Pls help
|
|

What do you mean by lock? It doesn't sound like the standard definition of the term. Besides, using .lock just changes the file extension, not any exclusive rights to the file.
Are you trying to get exclusive access to the file? If so, then your Open statement should look something like:
Open "filename.ext" For Binary Access Read Lock Read Write As #1
Use whatever File Mode and Access you want, but the important part is the Lock modifier.

hi RageInTheMachine9532,
you r right i dint mean the std locking of files. i want many app instances to share a folder of .tif files. if app1 is using a file, it renames it with a .lock ext so app2 knows it is being modified by checking the ext.
before an app exits, it renames files its been using from .lock to .tif.
problem is if app1 crashes, the files remain with a .lock ext n neither app1 nor app2 can use them!
how do i handle this? i mean without resorting to the normal windows locking..

Well, the locking is the only "sure" way to control file access and you don't have to deal with renaming stuff back when you crash.
The problem you have is this:
When AppInstance1 checks for the availability of File1.tif, it's there. The next step, is for it to rename File1.tif to File1.locked. But, What if AppInstance2 found that File1.tif was available at (nearly) the same time, say, between AppInstance1 finding the file and renaming it? In this case, BOTH instances will find the file, but only one will succeed in renaming it. How is this case handled?
It's too much of a pain to write your own file locking scheme when Windows has locking built in. It also has the advantage of being "thread safe", where your custom scheme does not.

Print a Microsoft Access report from VB 6.0
As you may know, Microsoft Access provides a much more robust reporting
system than Visual Basic. As a result, if you use Access as a back-end
to your application, you may want to print Access reports from your VB
application. Fortunately, you can do just that with Automation.
The following code shows one way to do so, using late binding. remember to replace dbName and rptName with correct values:
Dim objAccess As Object
Private Sub Command1_Click()
Dim dbName As String
Dim rptName As String
Dim Preview As Long
Const acNormal = 0
Const acPreview = 2
dbName = "D:\PathToDB\db1.mdb"
rptName = "MyReportName"
Preview = acPreview 'acNormal
With objAccess
.OpenCurrentDatabase filepath:=dbName
If Preview = acPreview Then
.Visible = True
.DoCmd.OpenReport rptName, Preview
Else
.DoCmd.OpenReport rptName
End If
End With
End Sub
Private Sub Form_Load()
Set objAccess = CreateObject("Access.Application")
End Sub
Private Sub Form_Unload(Cancel As Integer)
On Error Resume Next
objAccess.Quit
On Error GoTo 0
Set objAccess = Nothing
End Sub

My advise to you is prioritize. Seems to me that the functionalities you describe can best be split in several solitary programs. Prioritize and start from there.
Grtz, Guus

looking for Teacher and Student Records Managent at first hand...

I'm doing a project to write a system using Vb6.0. The system is very simple but for me is very hard. The most difficult part is to comes out with chart. The chart is to analyze the stocks. The system is a system for a shop seeling clothes one..Anyone can help pls reply. Thanks
|

Your question puzzles me slightly. But from what i understand is that you need to produce some sort of chart.
Excel is equipped with a wide range of charts. Use code to populate an Excel spreadsheet and open it.

I have written a small script in VBA which I need to deploy to a number of machines on a network.
Is there an easier way other than manually importing a .bas file into Outlook?
I found reference to a program called Desktop.VBA but every link on every site I found pointed to the same dead server...
Any and all help would be greatly appreciated.
Cheers,
Simon.

Simple. Find out who owns the IP address this person is using and report them. ANything you do to the other guy carries the risk that your going to get busted.\

Take a look at the System.Data namespace.
If you are using SQL Server, read about System.Data.SqlClient, if not, System.Data.OleDB.
Free your mind...

Or when you are using a connection string in VB go to http://www.connectionstring.com
