How do i know in which drive windows is installed

i need to invoke a windows method. For this i call an exe file from windows\system32 directory. But i need to know in which drive winodws is installed. I think it is not wise to hard-code my code -"c:\windows\system32". So can any one tell me how do i know this path from my program in run time?

Thanks

I use System.Environment.ExpandEnvironmentVariables to expand %windir%

e.g.

string MediaDir = System.Environment.ExpandEnvironmentVariables ( @"%windir%\Media\" ) ;

Look for the Windir system variable in the environment variables...

System.Environment.GetEnvironmentVariable("windir") will return the string where Windows is installed Smile | :)

A better solution is System.Environment.GetFolderPath( System.Environment.SpecialFolder.System ).

You set your Data Source property to what ever query/view or stored procedure you are getting the data from. You then set Display Member to the field you want to display. Value Member is the field value that you want the selected value to return.

Hope this helps you out.

There are no "commands" to do this. You'll have to program this behavior yourself. See this[^] implementation of a drawing canvas that may help you get srtarted. Also see this[^] implementation of a rect tracker.

displaying shapes that can be selected, drag and drop

Hi,

I want to create a form that has 2 areas. One area is where all the pre-drawn shape is located and the other area allows the shapes to be drag and drop onto it.

should i use custom control for the area that allows the shape to drag and drop onto it? How about the other area?

how to ensure that the pre-drawn shape is able to be seen all the time and any one of the shape is able to be selected, drag and drop to the other area?

Any tips what i should do and what kind of classes that i should use?

Thanks

hello,
i need a command line, and for it i used "Environment.GetCommandLineArgs()"
its working good and giving a gud command line but C# needs path with "\\" instead of "\", and CommandLineArgs giving path with "\"
thats why i tried to replace "\" with "\\" but when i use "\" then VC# gives 11 errors in only that one line OMG | :OMG:

thats all

Hi,

in C# (and C and C++ and Java) you cannot have just a backslash in a string literal.
Each occurence of \ will consume the next character and replace them both by one
character; examples \n stands for newline, \t for horizontal tab, ...
and finally \\ stands for backslash

So if you want to write a path literal, it would look like "C:\\temp\\file.txt"
where each \\ represents one backslash.

You can turn off all the above, by prefixing a @ sign like so: @"C:\temp\file.txt"

When a variable is holding a string, it holds the actual characters, not the above
conventions (that apply to string literals only). Hence the command line you obtained
will not contain \\ and is perfect for file I/O operations as is.

Hence your statement "C# needs path with \\" is wrong, it is string literal that
wants this (unless @), but not string variables.

Smile | :)

its a string thats working

string abc = "C:\\Documents and Settings\\user\\Desktop\\project\\bin\\Debug\\project.exe %1";

this isnt working

string[] args = Environment.GetCommandLineArgs();
string cm = @args[0] + " %1";

now, any other way or solution... Sniff | :^)

Hi,

"isnt working" is a bad description; if compilation fails, the compiler gives an error
message and a line number, so you should report the exact error message and indicate the
precise line where it happens; this will yield the best reply on these forums !

xmen_xwk wrote:
@args[0]

is wrong: @ only acceptable in front of string literal, not in front of string variable.

And what is it you plan to do with cm ?

%1 would not work for Process.Start()
it would work for file extension definition in Registry

I am sure you should not already be manipulating the registry programmatically,
when you still are a beginner in C#, or so it seems...

yeah, as i said "it isnt working" that means not working, it never give any error

Luc Pattyn wrote:

i m associating the files,

i have to set my application path in registry thats why i m doing this
the first code is working
and the second isnt working

im saying isnt working because when i click on button that have the first code(its setting the registry), the file directly opens(when click on file) but when i use second then the file doesnt open

i hope you understand....
thanks

Does System.Windows.Forms.Application.ExecutablePath() work any better?

What do you get in cm?

cm and this are same but cm have " %1"

the cm is that what i need but just difference is, it have "\" instead of "\\"

cm = "C:\Documents and Settings\user\Desktop\project\bin\Debug\project.exe %1";

i need

"C:\\Documents and Settings\\user\\Desktop\\project\\bin\\Debug\\project.exe %1";

checkedListBox edit item

This may be a dumb question (total .NET newbie here), but how do I allow the user to edit an item in a checkedListBox control?

With a treeView control I call treeView.SelectedNode.BeginEdit() but I can't see an equivalent method for checkListBoxes. Am I missing something really obvious? Thanks!

As far as I know, it is not possible. You would need to implement that functionality yourself. You could try creating a textbox and positioning it over the item you want to edit. I've seen it done before, just not in C#.
