Thank you for your answer.
I have read that article you have linked. It is a sophisticated solution. But there is only one problem, There should be an AppStart.exe to start the updated solution.
I can only have one executable, that's why I was trying to work with batch files.

Can you not set the ScrollBars property to either Horizontal, Vertical or Both.

The only method I can think of would only give an approximation, so for what it is worth.
The VisualTextRenderer class has a GetTextMetrics method. The structure returned contains details such as FontHeight, AverageCharWidth, MaxCharWidth etc. for the Font and Graphics it is given.
You could divide the height of the TextBox by the FontHeight to give the number of lines. Then use either Average or Max Width to calculate how many characters fit on a line.
I have no idea how accurate this would be though.

Unless the process exposes some kind of ommunication mechanism, there's no way to tell.

The FSW won't work for you anyway since it can't tell that a file was opened at all. All it can see is the changes in the files timestamp attributes, which don't change if you open a file for read access.
lost_in_code wrote: i want to get it in another way(i mean what process x is openning or modifying at a specific moment).
The only way I can think of would be to enumerate all the process handles, and all of the file handles in the system and start trying to match them up with each other. But, there is no way to tell an .EXE file from a .DLL file from a .TXT file from a .DOC file, or any other file type. On top of that, most apps out there don't hold files open when they load them, so there's no file handle to try and match up anyway.
The bottom line is what you want to do is extremely difficult and unreliable.

Hi,
welcome to CodeProject
1.
there are over 20000 articles here; at least one of them deals with Number To Text Converter[^]
2.
TextBox events are explained in the documentation. Use Google to locate them.

Hello,
I have a string variable in Form1. I receive the string from a datagrid
I want to pass it to form2 and use it there as a query to another datagrid in this form. How can i do it? I mean the passing of the variable itself?
|
|
|
|
|
Have a public property in Form2
public string QueryString
{
get; set;
}
Then when you create an instance of Form2
Form2 queryForm = new Form2();
queryForm.QueryString = "this is the string";
queryForm.ShowDialog();
then in queryForm the string is available to do whatever you want with.

Ok.
And do i need to add new windows form or new iherited form (i mean in add new item window in visual studio)?
|
|

You said that you have a form1 and a form2. Why would you need to add another form? Where I have used queryForm just use your existing form.

Yes.
But i haven't add form2 yet. So how do i need to add him (as new window form or inheirted form- How can i know it?)?

Same as you would any other form.
michaelgr1 wrote: as new window form or inheirted form- How can i know it?)?
I've no idea what you mean by any of that.
What do you mean by "window form" and "inherited form"?
There is a Form class, when ever you create a form you inherit from it. That's it. End of story. So, I don't understand where you are seeing a distinction.

When i do the get, set i receive an error says:
"'Focus_Report.Form2.QueryString.get' must declare a body because it is not marked abstract or extern"
"'Focus_Report.Form2.QueryString.set' must declare a body because it is not marked abstract or extern"
What do i need to write there to make it work?
|
|
|
|

You need to provide body for get and set. Something like
public string QueryString
{
get
{
.....
}
set
{
.....
}
}

What version of C#/Visual Studio are you using?

I use visual studio 2005.
How do i know what i need to write in GET and SET body?
|
|
|
|
|
OK.
I had assumed that you were using 2008, my bad. 
Change
public string QueryString
{
get; set;
}
to
private string queryString;
public string QueryString
{
get
{
return this.queryString;
}
set
{
this.queryString = value;
}
}
Then inside your form2 you can use the private queryString, and from outside form2 use the public QueryString.

Hello,
What is the difference in declarations in Visual studio 2008 and 2005. Why it 2008 we don't have to write this code?
BTW, I wrote only:
public string QueryString;
Is it enough? or i still need the constructor and why?
Sorry about the bothering and thanks again very much for your help.

In Visual Studio 2008, for simple properties you only have to write it as I showed the first time, VS does everything else to make it behave like the second example I gave, behind the scenes. In VS2008 they are called Auto-Implemented Properties.

What you have done, should work. BUT it is considered to be bad programming in OOP (Object Oriented Programming, just in case you didn't know). It breaks several of the 'rules', most notably the Data Hiding principle. Google on that for a more detailed explanation.
For now, though, consider the case that you wanted something to happen automatically every time QueryString changed. With your method it will be very, very difficult. With the second method I posted it would be very easy, and what's more it would be less likely to break some other part of the code.
Like this:
private string queryString;
public string QueryString
{
get
{
return this.queryString;
}
set
{
this.queryString = value;
this.MyDoSomethingWonderfulWithQueryStringMethod();
}
}
If you later had to change the way that MyDoSomethingWonderfulWithQueryStringMethod() works, you can, and as I said it is unlikely to break anything else.
