Hi guys!
Does anybody has any idea how to draw in different layers, so to be able to turn off a layer when not needed any more and get the original picture back? I find it sometimes too expensive to redraw a whole picture if I just need to remove some icons or other item drawn on it, or to calculate a rect of the pic to be "cut off" and then bitblt-ed from the resource bmp again to "fill the hole".
Any help, idea, or pointer to something similar would be greatly appreciated. Thanks.

Use double array:
Use a vector of graphical objects for each layer.
Use a main vector to store all the layers.

Does anyone know a "good" book about software development on win ce and pocket pc with C++ ???

Nice greets, Daniel.

Id say Chris Muench's book The Windows CE Technology Tutorial [^]is the best one I've seen. It covers alot of the diffrences between CE and the desktop.
Otherwise, any good MFC/win32 book + MSDN's CE pages will do the trick.

As a beginer of ATL Based Web Service programmer, I have some some questions about it:
1)Whether a Web Sevice can hold its state during its serving many clients, for I want keep some data structs among clients because these clients are collorating doing a certain work. If Web Service can has this virtue, how can I do, are there some documents about it?
2) can a web service client dynamicly locate the server without recompiling its source files When a Web Service provider changes its location on the internet? If it can, how can I do and are there some documents about it?
Please help me, thank you!

Hi All,
I need to kill a already running exe through my program whose execution I started through the system("filename") command of C.How do I do this.Is there any method available??
Thanks

To kill a process, use TerminateProcess. TerminateProcess needs a process handle - you'll have to use CreateProcess or ShellExecuteEx instead of system("filename").

... or look it up using one of the MS API's (different for every platform and blah blah blah...).
There is however IIRC a library for this here at CP. Maybe you should browse around a bit.

What if there's more than one instance of 'filename.exe'?

Then you're in trouble! 
Do you know anything else about the app, like Window Class, Window name? Actually, what do you know about the process you want to kill?
|
|
|
|

I have no idea what's the Window Class. Maybe you should ask original poster about that?
Anyway, I think switching from system to CreateProcess/ShellExecuteEx is waaaay easier than firetrucking with enumerating processes.

What kind of data structure would a control like this use...? What kind of loop would you use to iterate the entire array...? Assuming you use and array and not a linked list or something...?
In a very loosley typed lang would it look anything like this???
struct TREE_ITEM{
TREE_ITEM Parent;
TREE_ITEM Child;
CString Caption;
DWORD CommandID;
}
I'm not really interested in Treeview structures only it's more curiousity about how hierarchial structures work. So please don't mention how I may have missed a field inside the TREE_ITEM structure like CImageList or something...
Using the above structure makes iterating an array confusing as heck.
while(TREE_VIEW.Child){
}
The above seems (I'm almost positive i'm missing something) to trivial???
This would only intereate the top most parent items, but what about children of children and such...?
Thanx!

my experience of iterating CTreeCtrls has always been using recursive functions.
ie (pseudocode)
void ProcessTreeItem(HTREEITEM hti)
{
HTREEITEM htiChild = GetFirstChild(hti);
while (htiChild)
{
ProcessTreeItem(htiChild);
htiChild = GetNextChild(hti, htiChild);
}
}

i need something like mutex that will not be destroyed by windows after the process terminates, so another process can see it later on. any help plz?
|
|

First of all I do not know sth about this, but I think this is bad design what You achieve with this. Think of many processes leaving their garbage in memory after they have terminated. This will lead to many problems. If You want to do sth like this You could create a new process where in its main it is only creating this mutex as You need it. The behaviour could be controlled by command line arguments.

You don't need a mutex replacement. Do it like MS, use the bloated ini-file-from-hell (the registry).

This is possible, in principle, using native NT API. Every kernel object that is represented by a handle has an internal "persistent" flag, that protects it from close (until next reboot) even if the last handle to it has been closed. Of course this makes only sense with named objects, because you have to find it later on.
However, this works only NT4 and above.

I've written a class library in VC6 before, and now compiled to VC.NET now. It uses pointers to link with different classes within the library. Now, I want to use C# to develope the interface, but I need intensively use the class library. Can I do it ?

I believe it is not possible to run Netmeeting (or any other video chat except yahoo messenger) from behind a NAT router...
