var is a Microsoft mechanism that allows VB last-resorters to be okay with using as more appropriate strongly-typed language rather than comply with the actual paradigm of being a real programmer.
In essence, it is the "safe space" of programming constructs and as such, is used only by flaming lib-tards that think all code should be equal in the eyes of the compiler.
THAT is what's wrong with var.

"Browse ith record in the GridView if error rerun faulty records" this is my request, using a while loop 2, while outer ring running again if the ith sample error message, the sample code below if An error occured not run very well, but there are problems caused ith GridView on jump number and apparently does not run again faulty records, when defective block catch (Exception ex) is run, it gets in the error message in the block catch (Exception ex) and i will run continuously variable for every row (or rows) of the GridView, thanks to the help you troubleshoot.

{
DevExpress.XtraGrid.Views.Grid.GridView Gv = (GridView)sender;

i = 0;
while (i < Gv.RowCount && bStop)

Sorry, but I didn't get any idea of what your problem is from that, or any clue as to what help you need.
Remember, we have no access to your data, so we can't run your code under the same circumstances you do to spot problems.
What does the debugger say is happening when it does something you didn't expect, or doesn't do something you did? What did you do, what data is it working from to cause the problem?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I have formatted your code correctly but I am afraid it still makes no sense. Why do you repeat the same while loop inside the outer one?
|
|
|
|
|
because when browsing to records ith if an error message will jump to the next record, if there are errors it will run the loop outside. if no errors it will run the loop in. it did not escape the function catch (Exception ex) when faulty, endless loop.

HI to all ^^
May I ask if there is a right code for reading a response of port from declaring a command to send via AT commands, which the commands is AT+CREG and read the reponse of this command (AT+CREG)
please help
and thank you very much

As of now, I use a C#.net platform in a GSMComm library format but GSMComm has no method in how to fetch the format for AT+CREG and still i'm still searching to gain more ideas to achieve the pattern and i've stuck about parsing to read the response of AT commands as an output using AT+CREG that possibly result in a format
AT+CREG?
+CREG: 2,1,"02D0","CB9B"
and I need your help to guide me in how to achieve at least this format
any type of methods and properties of C#
thank you very much

UML is a part of Ultimate.
Sometimes I wish I could justify that particular expense.

If you just want UML, then use Visio Pro; with Standard (or the "Student") you can usually find free templates on the web for UML.
Visio "Architect" is what you're otherwise referring to; i.e. generate software out of Visio / reverse engineer.

I have a requirement of reading the current directory opened in foreground Windows Explorer.
I am checking whether windows explorer is in foreground or not from this.
how to do this ? please help me.

I need the lines of code to help me link text to pre-recorded sounds.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
All we get to work with is exactly what you type: we get no context beyond that...

Well, you could convert the "sounds" to text; or the text to "sounds"; and compare them...
What would you like?
|
|
|
|
|
What do you want to achieve? What's the input, and what should be the result?
Do you have some text and some sound file corresponding to that text, and now you want to create an application which shows the text, plays the sound, and highlights the position in the text? Or plays the sound corresponding to some selected part of the text? Or ...?

I have a requirement of enabling drag option for border less form within a fixed location of screen.
I am reading the windows explorer’s position for this method. Then I will place an icon within window’s explorer window and planning to allow dragging of that form everywhere inside the windows explorer.
How to do this ?
|
|
|
|
|
I'm not clear on what you describe here.
You find the current position of Win Explorer ... what if there are multiple folder views open ?
You move an icon within a Win Explorer window ... how do you keep it on top ?
What is the borderless Form you refer to ... what is its relationship to the icon, or the Win Explorer window ?
Making a Windows Form draggable is easy; how do you want the user to start dragging it ... by click-dragging anywhere on the Form not covered by a Control ? by clicking on some visual indicator ? by clicking on a certain region in the Form ?

I manage multiple windows with the handle of the window. See my previous question.
I am keeping the form on top of explorer by setting "me.topmost" property.
I want to allow dragging of form on mouse left click down everywhere inside the form but that form should be draggable within specified location of window (i.e within windows explorer window)

You still have not clearly explained what the use of the Icon and the Form isQuote: I want to allow dragging of form on mouse left click down everywhere inside the form but that form should be draggable within specified location of window (i.e within windows explorer window)
This statement implies you have two Forms, and that one is dragged within the bounds of the other.
Please try and describe clearly what you are trying to achieve, and, why are you trying to change the appearance of what the user sees in an Explorer Window ? Describe exactly what your app creates.
The use of "me.topmost" suggests this is a VB Project ... is that correct ?
