My issue is :
I have a application with more the one windows forms
At one stage in the application i am showing 2 forms, say “Form 1” and “Form 2”..
“Form 2” is called by “Form 1” and “Form 1” is still shown in the back (Not hidden). Now i do some updates in “form 2”, close “form 2” and show “Form 1” back...
On Activate of “Form 1” i was making some buttons disable depending on if “form 2” is shown or not... Hoping that when i come back from “Form 2” activate will be called.. But it is not working..
I even tried calling “form 1's ” activate form “form 2's” closed and dispose but no luck...
I can not close "form 1" so i tried with by hiding and showing "form 1" in the function where i am coming back to "form 1", but it dose not worked either
If i take the focus out of “Form 1” and come back it work... as then form activate works..
Can any one plz help me

From your description, you should be showing Form2 by calling ShowDialog on it, instead of Show. This will restrict the user to using only Form2 until it closes. Then control returns to the code in Form1 on the line after your call to ShowDialog.

No one is going to just give you code, and you need to be specific about your problem you are having.

Good morning all
am a new to the subject of threads in vb.net,i have a book that explain, but am not satified, i googled some tutorials and article, and found something.in the examples in the book, they sub's than functions, in my case, i have a function that return a dataset, now i follow the code correctly and i have a problem, when i try to do this, i know the function accept parameters and return a dataset.
Public Function SaveProperties_Lis(ByVal dsDAta As PropDAL.Dssearchlis) As PropDAL.Dssearchlis
SyncLock GetType(Properties)
Dim ws As PropDAL.Properties
Try
ws = New PropDAL.Properties
'check the Business Rules
Me.CheckRules_Lis(dsDAta)
'Updating the dataset
dsDAta.EndInit()
ws.UpdateLis_search(dsDAta)
Catch ex As Exception
MsgBox(ex.Message)
End Try
Return dsDAta
End SyncLock
End Function
.
Am trying to save data, but before i check for business rules violation and save, the whole process is working , but now because of Concurency, i thought i could use threads to lock the Function when two instances of my application try to run update function.
Dim a1 As New Properties
Dim thread1 As New System.Threading.Thread(AddressOf a1.SaveProperties_Lis())
.
In the above the Errors screems inside this Function, it says
Argument not Specified for Parameter Dsdata .
What parameter should i use?
The above Function take a dataset as a parameter, so what should i use?
i would like to confirm, if the above code, is Delegating?
Thanks

That error means that your haven't supplied a required parameter for one of your SQL statements. What SQL query were you trying to build and run when at the time the error showed up? That's where you should be looking for the problem.

When we are trying to install one of our applications developed on VB 6.0, on a XP Prosessional machine, the setup starts, gives a msg "Some file in the system are old, Setup will Update files and restart". No matter how many times we restart, the same message keeps occuring, and the setup does not continue at all.
Can someone pl help us out?

Guy, did you actually look at the results you got back from Google?? NONE of results on the first page refer to the issue described by the OP.
It would be nice if you read your answer thoroughly before posting it.

Actually, HERE[^] is your answer on MSDN.

i had made a smtp to send a mail i want to know thta the mail is gone to the sender mail id or not for that i need a code if any one have code for delivery report so pls mail me its urgent
|

There is no way to tell if the email got to the target mailbox. The best you can possibly do is say that the email was sent from your machine to the mail server. That's it.

OK. Since you've already sent a message, all you do is send another one to the senders address. What's the problem?

I am running Windows XP Pro SP 2, have Office 2003, installed SDK 5.1,
Visual Studio 2005 with installed .NET Frame 3.5 (re-distribution package).
I tested out the voice the recognition code from this link but seem it
can't recognize System.Speech. I try to search for (Add Reference)
both in .NET & COM (found none.)
Is there any else I need to add to make this work. Thanks

VS2005 can do nothing with the .NET 3.5 runtime. You need VS2008

You cannot use .NET 3.5 with Visual Studio 2005. The highest you can use is .NET 3.0, which doesn't have the System.Speech namespace.
|
|

System.Speech is in .NET 3.0.
C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0
It doesn't contain:
Recognition.DesktopRecognizer
GrammarBuilding.SrgsDocument
GrammarBuilding.SrgsRule
GrammarBuilding.SrgsOneOf
I look at .NET 3.0, they have System.Speech.Recognition.SrgsGrammar.SrgsRule
So my best guess that the namespace/class is a little different?
|
|
|
|
|
So it is. Shows you how much work I've done in .NET 3.0.
|
|
|
|
|
I been googling for sample source code or new documentation on how to integrate System.Speech for voice recognition in VB.net. I didn't find any yet. Any sample source code will be great.

I've made a Visual Basic 6 program related to a database.
I want to make a dinamic chart in Visual Basic using this database data, but i don't want to make it myself because is too hard.
I made a chart in Microsoft Word using Visual Basic code, but I want it to be made in a form in VB 6 for example, if that's possible.
Thank you very much!!!

Nope. You'd have to do quite a bit of rewriting of the code, thereby doing it the "hard way" anyway.
