It looks like your code is trying to create a COM object, but that COM Server is not installed on your machine. Step through your code, line-by-line to see where the error is occuring. All you have to do is hit F10 instead of F5 to start your app and stop after the first line of code. Hit F10 again to do the next line, and so on...

thanx for reply.
error is generated on InitializeComponent()
|
|
|
|

When you get to that line, Hit F11 instead to "Step into" that code.

Again, without the code, posting the stack trace is just about useless. The top of the stack says there was a problem creating an instance of a COM server. When you code gets to InitializeComponent, hit F11 to step into it and keep going until you find the line that bombs.

I know 1.1 didnt but Im curious if 2.0 does. I want to list the currently opened windows in an application which could be unlimited technically and would like to be able to create a new MenuItem at runtime for each open window. I already have a plan for knowing the open windows.

What you have described is possible in .NET 1.1
A MenuItem is an object, just like any other. You create one and add it to the appropriate parent menu item.

Wow I had some bad wording on my question...
I meant to ask dynamically named and created controls where I dont have a set number of values which isnt what I really needed anyway, but thanks!

How am I supposed to do this? Even with public Sub or Function definitions intellisence isn't displaying the methods when I type Me.SubFormName. while editing the code of the parent. I tried just typing the name of the method in manually to see if it was just an intellisence problem but that triggers a runtime error because "the method or data member not found".

i am using vb.net 2003.i am doing my project in vb.net windows application.
how do i remove selected row permanently from sql database through datagrid in vb.net windows form during runtime.
for example,
values are in datagrid like
name age rollno city
ramu 22 68 chennai
rajesh 23 70 cbe
kamal 21 52 salem
arun 25 04 trichy
here name,age,rollno,city are field name.now i want to remove selected row permanently from sql database through datagrid.In this datagrid,if i select "kamal" row(kamal,21,52,salem) means,that kamal row will remove permanently from sql database.how to do these.i want in vb.net windows application,not web application.plz help me.
|

|

If the datagrid is bound to the dataset, all you would have to do is select the row, hit the delete key to mark the row for deletion.
In your code, you would have to use an SqlDataAdpater[^] to update the database from the modified dataset. This code would typically be behind a "Save Changes" button on your form with the datagrid.

hi pls help me out in inserting text into a richtextbox.
the situation is like this::
i want to insert a string say "hello" at a particular location in the rich textbox.
The particular location is given in the form of X and Y coordinates.
eg:: PutString("hello",10,20)
i write a function that passes the string and x,y coordinates.
is that possible??
x,y coordinates will represent the location of the string in richtextbox.
any ideas.. pls help!!
thnx....
ajith

Sure. In your "PutString" method, you'd have to call the RTB's GetCharIndexFromPosition method to get the character index of the point in question. Then it's just simple string manipulation, using the Insert method on the string returned by the RTB's Text property.
Dim charIndex As Integer = RTB.GetCharIndexFromPosition(point)
RTB.Text = RTB.Text.Insert(characterIndex, newText)

how to send screen resolution on serial port in VB
|
|
|
|
|
The screen solution would just be a couple of numbers. You send that as a string out the serial port just like any other string of text.
First, what does the device that your sending this information to expect? In what format does it expect this information?
Second, which version of VB?? VB6, VB.NET 2002, 2003, or 2005?

You can step into the dll from your app in the debugger, to see what the issue is

You're going to have to step into the code for the .DLL (provided you have the source code for it!) and find out what's going on in there.
With the description of the problem you gave, that's about the only thing anyone can tell you to do. You haven't said anything about the code, any exceptions you're getting, what the thing is supposed to do, ... nothing. Because of this, it's really hard to give any advice that would mean anything.

Solution 1: buy a magic lamp and carefully consider how you are going to formulate each of three wishes, and polish the lamp.
Solution 2: If you have more than three wishes, be very nice all year, send a list with your wishes to Santa Claus, The North Pole, and keep you fingers crossed.
My advice is free, and you may get what you paid for.

Hi All.
My program need to kill a process, and it works well .. BUT:
When the process die, leave a taskbar dead icon that goes away by passing with mouse on it.
So my question is:
There's something like a Taskbar.resfresh() method that could make that work for me??
any other idea??
Thanks!
G.

|

No, there isn't. You've foudn the only way to make that icon disappear.
