Hi guys , just wondering if anyone knows much about global mouse hooks in c#. I ve basically used this tutorial to implement a simple hook that can grab mouse clicks and x & y.
http://www.codeproject.com/csharp/globalhook.asp[^]
I now have a requirement where I need to specifically get the name or text associated with the item ive clicked on. IE if I clicked on the 'File' menu in wordXP id like to be able to get the word 'File' and store it in a variable for future use.
Iam pretty sure this task is going to involve monitoring windows messages but iam not really sure where to start. does anybody have any experience in this area?
Thanks Mike

I have an C# ASP.NET web page. I have this conversion problem with my string array to my session variable.
string[] stModArray = (string[])Session["modArray"];
Any suggestions...... Thanks in advance!!

Hello,
As the Session["modArray"] is only returning a string or null you can not cast it directly to string[].
You would have to create an string[] instance and add the result string to the array (at the index you would like it to be).
To make it dynamic, you caould use a System.Collections.Specialized.StringCollection (with the "add" method) instead of string[].
P.S.: allways make a !=null check.
Hope it helps!
All the best,
Martin

Do this:
object o = Session["modArray"];
and check in the debugger to see what's actually stored there. If it's not a string[], you can't turn it into one, at least not like this.

Ok, what I have in this variable are three primary key numbers, so what's getting stored is an int. But the reason why I'm using a string is because I need to return the length for my for loop so the user can cycle backwards and forward viewing each record.
-> There are no nulls getting passed in, what's getting passed in is correct.
This is the snippart of the code that I'm using to try and do what I've just explaned. Once again since I'm I using a loop, objects and such don't have the length function :'(
private void nextMod()
{
string[] stModArray = (string[])Session["modArray"];
for (int i=0; i

Hi,
I have some custom controls and all have methods BeginInit() and EndInit() in it.
In most cases both methods are empty and probably will always empty.
Is there any performance problem, because I notice in myForm.designer all controls have this two lines:
((System.ComponentModel.ISupportInitialize)(this.crLabel20)).BeginInit();
(System.ComponentModel.ISupportInitialize)(this.crLabe20)).EndInit();
I suppose for all controls both methods are called at runtime. Is this performance wasteful?
Thanks and sorry my english,
Jure

Hello,

Yes, it will be called from the constructor (InitialzeComponets) of your form. (When you initialize your form)
Tavbi wrote: Is this performance wasteful?
No!
I wouldn't care too much about it.
But maybe if you don't need it at all, you should think of removing it, just to make the code simpler.
All the best,
Martin

Err but it looks like these were generated by VS. I wouldn't touch them.

No, No, No!
What I mean is removing the interface from the Custom controls (labels,...)
Hope he understood it.

Since that's deigned generated code, the changes you make in there will be overwritten the next time the designed refreshes it. You can also break the designer by messing with that code too!

This must be the seventh time you're asking the same question in the last few days.
Last time kubben asked you if you have tried HttpWebRequest.ClientCertificates and you didn't answer.
HAVE YOU??

Hi all,
I have to switch from one application to another,
I have found this method:
System.Diagnostics.Process.Start("application");
that allow me to open an application...
Then when i press my button for the second time, i don't want
to start a new application but i want to open the existing one.
in this way:
System.Diagnostics.Process[] myProcesses;
myProcesses = System.Diagnostics.Process.GetProcessesByName("application");
i can know if my process is already running but now I don't know
to show this application...
Can someone help me??
Thanks a lot.

Hello,
You could use the MainWindowHandle property of the process in combination with BringWindowtoTop method of user32.dll.
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern int BringWindowToTop(IntPtr hwnd);
public IntPtr HWND_TOPMOST =(IntPtr)(-1);
public IntPtr HWND_NOTOPMOST =(IntPtr)(-2);
System.Diagnostics.ProcessStartInfo psi;
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Maximized;
psi.FileName = "???.exe";
using(System.Diagnostics.Process process = new System.Diagnostics.Process())
{
process.Start(psi);
process.WaitForInputIdle();
BringWindowToTop(process.Handle);
}
I'm using this in .Net1.1, maybe in .Net 2.0 there is a more elegant way.
Hope it helps!
All the best,
Martin

Yes thanks this work fine...
The only problem is that I hope to find a method that works
without import user32.dll
So now i work with this but if someone know a method that not use
user32.dll it would be better..
thanks
