You might use the MouseEnter and MouseLeave events to keep track of
the presence/absence of the mouse in your application.
Remark: some special care may be required when you also use menus, since
clicking them seems to interact with the normal Enter/Leave sequences.

thanks for response ... but that does not help ... i need to know when the mouse is IN USE, not when it has left MY form.

OK  , sounds much like activity detection; this is used e.g. by screen savers,
so I suggest you look at one of the many screen savers on CodeProject.
Furthermore, you could look at a "global system hook" (as explained in
http://www.codeproject.com/csharp/globalsystemhook.asp[^]).

hi. I want to share a file (.cs) in two projects. I am writing server-client type seperate project s, they run at the same time, I have classes that I use both of them. I want to share a .cs file say sharedClasses.cs and want it to be compiled from the new code file. normally without this, I always copy the same code to other project's sharedClasses.cs..
|
|
|
|
|
I would make a project for main functions, compilled to a library, and one project for the client and server type, but in one solution. First compile the class, and after that the client and server.

I'd put the files you want to share into a dll

In Solution explorer, chose the projet you wish to shsre the file TO., right click and choose add->existing item.
browse to the file you wish to share and select it. BEFORE CLICKING THE ADD BUTTON, click the down arrow on the right of the add button, and choose "add as link" from the drop down. The selected file will now be shared to your project, rather than copied to it...
Who'd a thunk it - button cross bred with a combo. Took me for ever to stumble across that non-intuitive POS.

I have afew questions regarding the tab page control:
1) I have to force the user to not change the page untill a database is loaded. I used the invalidating event to force the user not to change focus untill the dataset is loaded. the only problem is:
i don't kow how to put the condition: dataset.tables.count!=0 is right??
and
does the validating event actually worg between tab pages?
2) I want certain tab pages to be either disabled (I mean to appear on the tab control disabled, not all the controls on it to be disabled) or invisible(likevise)
how do i do that?

1)If you use .Net 2.0 there is an event called DataSet.Initialized, and a property called DataSet.IsInitialized. When the Dataset finishes initialization, the event fires, and the property is set to true.

2) I don't think I caught up with you, but if I got you right, then you don't want to hide, nor disable the tabpages and the inner controls, yet you still don't want to allow changing the current page. You can handle TabControl.SelectedIndexChanged event, and check IsInitialized in it. If it wasn't true, revert the selected index to the page you desire.

1) you may write :dataset.tables[tablename].Rows.count!=0
2) tabpagechange event can handle this.
Sorry ...
|
|
|
|

yes, but how do i get the page(index or name) from wich the index/name was chaged? the tab control doesn't have a last selected page or last selected index property.
Another problem is the fact, i think, the tabcontrol selected index changed occurs after the tabpageenter event.

hi.
where i can get (ocr) for programing in mysoftwar?
tankyou.
|
|
|
|
|
You mean you want to make your program an OCR engine? In what language? The easiest way is to use office interop if it has OCR in it. Otherwise you'd have to buy an OCR component.

Hi There....
I am looking to iterate through A form's Controls collection. However i am also interested in control which are the child of panels. Is there any built support in WinForms? Or is the solution just to write my own little recursive method?
Thanks in advance
Aj

Hi,
yes recursion is the way to go:
private void LoopThroughControls(Control c) {
foreach (Control subControl in c) {
LoopThroughControls(c);
}
}
Within your Form just call: LoopThroughControls(this);

Thanks Robert - Quite an elegant little solution there....
|
|
|
|

private void button3_Click(object sender, EventArgs e)
{
treeView1.Nodes.Add(LoopThroughControls(this));
}
private TreeNode LoopThroughControls(Control c)
{
TreeNode node = new TreeNode(c.Name);
Control ctemp;
for(int i=0;i<c.controls.count;i++)
{
="" ctemp="c.Controls[i];
" if="" (ctemp.haschildren)
="" node.nodes.add(loopthroughcontrols(ctemp));
="" }
="" else
="" node.nodes.add(ctemp.name);
="" return="" node;
="" }
if="" you="" want="" to="" write="" xml="" for="" all="" propertys="" of="" controls="" form="" ,="" i="" may="" do...=""
<div="" class="ForumSig">Ok ...

hi,
i would like to know how i can communicate from e.g. windows shortcuts or context menu items in windows to my program ...
i think i will have a installer finally creating these and adding some registry values and they should e.g give me the location where e.g. the windows explorer is active atm ... ?
something like a context menu extension...
dont know where start searching ...
thanks a lot!
cheers phil

I think you mean shell extensions.

that the code i wrote
FileStream w = new FileStream("d:\\HufmanCompression.txt",FileMode.Create);
BinaryWriter writer = new BinaryWriter(w);
for (i = 0; i < array.Length;i++ )
writer.Write(array[i]);
w.Close();
The output i need is to write a binary file with a very small size(it is a compression prog)
thanx for ur time

I don't seem to see a question in your message? What's your problem exactly? Your code is one way of doing it. What's wrong with it?
Ps.
Make sure to call writer.Flush() at the end of your code before slocing the stream.

Doesn't Close flush the stream?
