So in other words it works for people who talk to themselves ?

It's pretty much impossible to help you here, you need to provide some code and let us know what you're trying, so we can point out where you're going wrong.

Best choice for data

I am working on a project for work, and was wondering what the best choice for data storage and recall would be. I only need to save three pieces of data per line, but need to be able to search with a match on two of them.

example:

data1, data2, data3
select data3
from ?
where data1=string1, data2=string2

While I realize that this is not proper coding for SQL, it is just and example. Any help would be greatly appriciated.

insert procedure in exe project

30-Mar-05 11:57

Well, if you're using SQL, then you're using a database, surely ? For a single flat table with three pieces of information, I reckon Access is sufficient.

What do you mean by "any startup event"? There is no startup event for an .EXE...
And what kind of procedure are you talking about?

You can't. You can't change an exe to have another procedure in it, it just doesn't work that way. If it's VB.NET you can decompile it, add your proc and recompile, I guess.

Erron in calling GetCursorpos Api

It's obviously not YOUR project, or you'd have the source code. Why are you hacking someone elses program ?

You haven't supplied enough information to troubleshoot the problem. You need to post the code showing how you declared POINTAPI and GetCursorPos().

For some reason, the CurrencyManager will not let me remove the last item in the collection. For example, if I have a CurrencyManager bound to a collection with a Form and Control bound to the CurrencyManager. I can remove any item from the CurrencyManager just fine with RemoveAt. However, if it is the last item , it simply ignores the call. It doesn't throw and error, it simply doesn't do anything. Count remains Same, Position remains 0. Even if I try calling CurrencyManagerVar.List.Clear(),
it ignores the call. Again, no error, just doesn't do anything.

But in my Another form it has worked fine with CurrencyManager.RemoveAt(CurrencyManger.Position)
Any Problem in my code?

My code is :

CurrencyManager.RemoveAt(CurrencyManager.Position)

I have also tried with
Dataview.Delete(CurrencyManager.Position)

And
Dataview.Delete(CurrencyManager.Count-1)
And also with

DatarowView = CurrencyManager.Current
DataTable.Remove(DatarowView.row)

above all are not working

well its very difficult from this code to pointout ur error
but i got two points

1. check ur startup object. is it sub main ?

2. u are writing dim frm as ew form1()
istead try out
public frm as new form1()

even if this does not work, then u better make a module
and write the staatement there
public frm as new form1()

then in main u can use frm.show()

hope this will work

My start up object is Sub main.

I have tried all the tips given above.

I would like to tell you some information....

My application starts executing from Sub Main(). Iam checking a condition in Sub Main procedure and based on that i displaying a form. So when i tried to do that form is displayed for few seconds and the application is terminated.

and i assure that there are no errors like logical or syntax error in coding

I hope that there must some other steps to display a form in Sub Main

Pls help me to find a solution......

Thanks

OK,

In VB6 you could do this and then if you displayed a form the application would continue to run.

In VB.NET even if you show a form in Sub Main, when Sub Main ends, the form will be destroyed and the application will terminate. There is a simple fix for this. The critical line of code you need is in bold:

------------------------------------------------------

Sub Main()

...your initialization code goes here ...

If ...your conditions are met... Then
MyForm.Show
Application.Run()
End If

End Sub

--------------------------------------------------------

If you want to open that form when your application starts then why dont you make it as startup object.

hey, it means there is some condition which is forcing ur program to end.

i also had faced such problem previously
then i put message box whereever i was doubtful in my code

u can also put msgbox in formload of form1.
this will tell u is form1 is loading or not
then u can put the msgbox in other functions of form1
this may tell u the code which is creating problem

my suggestion is to use msgbox and try to debug ur code

Hello,
You could try to put your conditional statements inside of the Form Load event. If the conditions are not met, you could then use Me.Close() to exit.

For an example,

If <conditions> then
'Do your stuff here if it is met
Else
Me.Close() 'Exit the application since the conditions are not met.
End If

I hope this helps,

I had this one about 2 years ago...
I had put some code inside my "form1" and found that the code ran, but the form seemed to never appear.
If you put a DoEvents after the show, then a Msgbox, you'll see what's happening... Your form is actually loading, but the program is exiting after the form.show method.

If you want to load the form and not exit "Main" until you close the form try using the ShowDialog method of the form instead of the Show method. I think that's what you are looking for.
