I want to show the WaitCursor when my app starts while it does some preparations before it shows the main form and starts the message thread.
So I can't use MyForm.Cursor = Cursors.WaitCursor because the message thread is not running yet.
Is there a way to change the windows cursor in another way?

Windows.Forms.Cursor.Current = Windows.Forms.Cursors.WaitCursor
Windows.Forms.Cursor.Show()

It doesn't work. Cursor stays normal.

the normal approach is to show a splash screen, which may or may not be animated. One way is like this:
Main() {
SplashScreen splash=new SplashScreen();
splash.Show();
SlowForm form=new SlowForm(splash);
Application.Run(form);
}
and the SlowForm could close the splash when it is far enough in its creation process.
BTW: if the SlowForm constructor is slow, you should consider postponing its slower parts ro a later event (Load, Shown) or even to a separate Thread.
PS: sorry, my example is using C#, you'll have to find the way to do something similar in VB.NET

Dear All,
I have a SQL database with 3 columns A, B, C. Under these 3 columns, there are 100 entries.
I want each row to be printed on each page of crystal report, so that i get a separate page for each row entries of the database.
Can someone suggest me how to implement this?
Regards
R.S.

You can check with crystal reports, from report field explorer, there is a field called Group Fields, there if you give your field as a group field, then your reports will be seperated by the same manner.
For Details, suppose your report like
S.No..Name...............Category
1.....Mr.Dave Kresoik....MVP
2.....You................Learner
3.....Me.................Learner
Now I added a Group By Field as Category, then PAGE-1
S.No..Name...............Category
1.....Mr.Dave Kresoik....MVP
And PAGE-2
S.No..Name...............Category
1.....You................Learner
2.....Me.................Learner

H1=[3/(5*sqrt(2)),0;9/20,1/sqrt(2)];
H2=[0,0;9/20,-3/(10*sqrt(2))];

H=[H0,H1,H2,H3];
G=[G0,G1,G2,G3];
B=zeros(2*k1,2*k2);
for i=1:4:2*k1
if (i+7)>(2*k2)
B(i:i+1,i:i+3)=H(1:2,1:4);
B(i+2:i+3,i:i+3)=G(1:2,1:4);
B(i:i+1,1:4)=H(1:2,5:8);
B(i+2:i+3,1:4)=G(1:2,5:8);
else
B(i:i+1,i:i+7)=H;
B(i+2:i+3,i:i+7)=G;
end
end
and the code
[k1,k2]=size(A);
WW2=gen2(k1/2,k2/2);
FF=ipermutesub(A);
FT=FF';
EE=ipermute2(FT);
DPP=WW2'*EE;
DD=icspreproc1(DPP);
CPP=DD';
CC=ipermute2(CPP);
AAP=WW2'*CC;
B=icspreproc1(AAP);

Soooooooo......what's the question?

I have a context menu running for a vb.net windows service controller I've created.
Folks can turn the windows service on and off with the application. I change the caption for the local mene each time the user changes the service status. (Startup service/ shutdown service)
This works great until somebody changes the service status independantly of my service controller. Then the captions don't match.
I'd like to capture the "right click" event of my context menu, so to speak, to make certain I have my service's status displayed correctly. I don't know how to do this with a dynamically created context menu.
I can add events associated with specific menuitem w/i my context menu without issue.

It's not very clear where you want this code to run. Are you saying that you have a context menu that pops up on a right-click of a form or some other control and you want to update the status then? Or do you want to update the status when right-clicking an item in the context menu??
It's easy to wire up the events using AddHandler. You just have to write the method up with the correct header, matching what the event you're going to use expects.

Would it be an option to get the latest status and setting the caption, just before the menu is about to pop up? In that case, you could wire up the PopUp[^]-event, and set the caption from there.

Is it possible to use all the Queries in Single DataAdapter, Dataset?
Also Iam using like the following
Dim Query1="Select * from Table1"
Dim DAp1 as SqlDataAdapter,Ds1 as new Dataset
Dim Query2="Select * from Table2"
Dim DAp2 as SqlDataAdapter,Ds2 as new Dataset
Dim Query3="Select * from Table3"
Dim DAp3 as SqlDataAdapter,Ds3 as new Dataset
con.open
DAp1=New SqlDataAdapter(Query1,con)
DAp1.Fill(Ds1)
DAp2=New SqlDataAdapter(Query2,con)
DAp2.Fill(Ds2)
DAp3=New SqlDataAdapter(Query3,con)
DAp3.Fill(Ds3)
con.close
Instead, Dap1.Tables(0), DAp1.Tables(1), DAp1.Tables(2) like wise, how to fill all in a single Dataset from SQLDataadapter?
THANKS
|

You can use multiple tables in the same data set. But, you cannot use a single DataAdapter to fill it. The DA's only work with queries that work on a single database table at a time. You CAN, like in your example, use multiple DA's on the same dataset.

i hav a table with schema
id int
name varchar
i declare trow as personrow
i bind it to a gridview onselectedindexchange i got the row selected by user as
dim row as gridviewrow = gridview1.selectedrow
how can i cast row to personrow
|
|
|
|

You don't. A GridViewRow represents the row in the GridView control, not the data inside it. You can use the returned GridViewRow object's DataItem propety to get a reference back to the data item that row is bound to.

In what context?
Are you trying to get the form names and show them in a list or are you really trying to show every form in your app?

Hi all,
has anybody work with data format "jdf"?
For example reading and writing?
Thanks for help
|

|

Is this a survey question or did you have an actual problem you were trying to solve?
Your best source of information on JDF is going to be Adobe.

scenario:
I have a Sql Server in Rome and a shared server dir (with the access database)
on a Server in New York.
I have permission on sever dir and databse.
The database table on sql Server have exactlly the same structure of Access
table database. (the table on Sql Server have 200.000 records and 48 columns).
Now i want to recopy all records from Rome(sql server) to NewYork (Access
database).
Wath is the best way in terms of time to recopy all records fom sql server to
access database.
note:
I want to use in my app the ADO drive and vb6 classic.
naturally other way are welcome

Hi Eddy.... tks for tip but sure not for me i know only VB6...
Can you post a code to use with vb6 classic?
Tks for patience.

Replication is done over SQL Server, and it doesn't speak VB6, only SQL. You should be able to talk to your Access-database using VB6 and ADO without any problems.
Alternatively, you could write some code in VB6 to do the import manually; creating an ADODB.Connection to SQL and writing it in your Access database. I'm going to guess that that's the code that you're interested in?
