Yes, but if the database keys are out of order or staggered, then the list control will not display all of the items. It will only display 0 through n items, where the items mentioned are contiguous. Any items after n will not display.

So then how would "incrementing the LRUindex at the end of the while loop" correct this? It sounds as though a separate variable is needed.

Agreed. He said he got rid of that column in the database and used a nonlinked variable.

The solution to both of your problems was given here. The columns of the list control are numbered 0-9, but you are only setting the text of columns 0-8. You may have a separate problem depending on if the list control has either of the LVS_SORTxx styles set.

Their is iItem and iSubItem, iItem is the first column containing the main title of whatever your trying to work with. Any other column after the primary column is a iSubItem.
So iItem = 0 & iSubItem = 0 to insert text in the first column, iItem = 0 & iSubItem = 1 to insert something to the second column. For the second row entry iItem = 1 & iSubItem = 0!

hi
try to use a return value of InsertItem function as index in SetItemText() instead the value that you use.
index InsertItem function returns is a current line. otherwise you can;t to know in which line your text will appeare

Modification: I didn't mention that I'm working under W7!
Morning all!
I have a GDI leak in a program that I'm trying to track down.
I've found various programs (GDIView, MemoryValidator, DPus, Deleaker), and none of them do what I want (though they have been useful to narrow the issue down).
What I want to do, is to be able to get a list of all the GDI handles that exist in my process - then I can make a before / after comparison to see which ones should be around, and which not.
The nearest functions I can find are GetObject, and GetObjectType - but to use those I have to loop around 4 billion times, and I get a lot of false positives - not to mention, it takes a LONG time to do 4 billion calls in an out of kernel mode.
There's also GetGuiResources, but that just gives a total.
Where's my EnumGuiResourcesEx function!?
Any hints? I've had a look at DbgHelp.dll too, and it does not seem useful in this case.
Here's hoping y'all can say "Oh, just look at the frobble sdk - it's perfect!"

I don't know if you have already checked out this [^] (moreover I don't know if it might be helpful, as it is a bit outdated).

Yes, I had... But it's out of date now.
I did miss out a vital fact that I'm working under Windows 7.
Thanks for trying though!

This might be completely useless, but Sysinternals do a utility called, IIRC, Handle. I think you can run it against a single process. Probably shows way too much, but filtering the output sounds a lot less painful than 2^32. You might need to cobble up some way of suspending your process at appropriate before/afters.
Good luck! Leaks are the original and best PITA.

I thought I looked at Handle - and on a further check, I had.
Sadly, it's great for events, file handles, etc - but completely skips gdi handles.
I checked out devenv.exe. I can't believe VS2008 doesn't have any bitmap objects open for it's toolbars...
So, nul point, but keep trying!
Iain.
ps. I didn't think this would be hard either, but...

There are probably shed loads of functions to hook, but could you hook the various Creates and Deletes for GDI objects and keep a count of what's using what that way? There was a time when everyone under the sun was writing API hooks so there are plenty of implementations out there for 32 bit code at least.
Cheers,

Hey!
Don't know if this question is still actual or not (better late then never i guess) but i found this: http://www.codeguru.com/forum/archive/index.php/t-176997.html[^], they talk about a way to query all the handles of a process and their "types", don't know if this can help you at all or not, maybe it doesn't even include GDI handles, didn't try it but i thought i share, perhaps it has some usefull info.

Nice search, thanks. It does talk about the sysinternals utilities - and they skip over GDI handles, so I'm not overly optimistic. But trying it out has to be easier than writing my own hooking stuff!
Thanks,
Iain.

Hi,
I am drawing png image on button using
Graphics grpx(dc);
Image *Img = new Image(L"dleft.png",TRUE);
But I have to put the png in the relative folder. I want to put it in resource file so that I can use only exe file.
How to do that?
|
|

|

I would describe the algorithm in brief.
Step 1:Add the image to your project as resource.
Step 2:Call FindResource to retrieve HRSRC handle for the resource.Next call LoadResource API function to load the resource into the memory.
Step 3:Call CreateStreamOnHGlobal function to get IStream* pointer to the resource.
Step 4.Use the appropriate constructor of GDI+ Image/Bitmap class to create the instance and release the resources if needed.
Life is a stage and we are all actors!

Hi,
I want to compare last five character.Is there any direct syntax for that.
Im geting secondary monitor size, to get that im using the follwing code
mi.cbSize = sizeof(mi);
GetMonitorInfo(hMonitor, &mi);
mix.cbSize = sizeof(mix);
GetMonitorInfo(hMonitor, (MONITORINFO*)&mix);
CString display;
display.Format("%s" ,(LPSTR)mix.szDevice);
if(strcmp(display,\\.\DISPLAY1)==0)
{
DualRect = mi.rcMonitor;
display.Format(" Res[%d,%d,%d,%d]",DualRect.left,DualRect.right,DualRect.top,DualRect.bottom);
AfxMessageBox(display);
}
Here display get string as "\\.\DISPLAY1" but in stringcomparison,it doesnot get passed.
Whats my mistake?
Like this i will strcmp with DISPLAY2 string and then i will get that second monitor screen size.

CString::ReverseFind[^]
or if you're too much into C++, string::rfind or wstring::rfind can be used.
I suggest you to use the CString version. You can find lot of string parsing functions in CString class.
To find whether a monitor is a primary or secondary, you can use dwFlags parameter in the MONITORINFO structure [^]

since display is a CString, the = overload may be used.
just try out this.
if(display=="\\.\DISPLAY1")
{
.......
}
and make sure, since you have \ as a character in a string, perhaps, you will have to use one more \ preceeding it.

Suggestion to the members:
Please prefix your main thread subject with [SOLVED] if it is solved.
thanks.

Well this will obviously not compile so I assume your copy and paste does not work. I am presuming that it should read:
if(strcmp(display, "\\.\DISPLAY1")==0)
but since the '\' character in a string is used to escape the next character this is still wrong, the resultant string passed to strcmp() will be "\.dISPLAY1"
It should read:
if(strcmp(display, "\\\\.\\DISPLAY1")==0)
It's time for a new signature.
