LVM_FINDITEM message

[SunCore]

Hi, when i'm using the following code, the application with the list view crashes.
Can someone please tell me what is the problem?
thanks in advance, and here is the code:


lv.flags=LVFI_STRING | LVFI_PARTIAL;
lv.psz=(LPCSTR)"str";
SendMessage(hw,LVM_FINDITEM,-1,(LPARAM)(const LV_FINDINFO FAR *)&lv);

Where does the code crash? Have you tried initializing the LVFINDINFO structure to zeroes?

i forgot to initialize the struct.

hi,
i m gettting the same prob when i try to send LVM_FINDITEM message to Windows task manager, it crashes. can anyone tell me what could be the prob,
and how to initialize LVFINDINFO to zeros, i could understand.

here is the code

LVFINDINFO aInfoStruct;
aInfoStruct.flags = LVFI_PARTIAL|LVFI_STRING;
aInfoStruct.lParam = NULL;
aInfoStruct.psz = lpszmyString;
aInfoStruct.vkDirection = VK_DOWN;

int index = ::SendMessage(hWnd,LVM_FINDITEM,(WPARAM)-1,(LPARAM)(const LV_FINDINFO FAR *)&aInfoStruct); // this line has the crash

thanx in advance

ZeroMemory(&aInfoStruct, 0, sizeof(LVFINDINFO));

...taskmanager is still crashing, I don't know this message is supported by task manager or not...

This message IS supported by any listview. You just can't pass YOUR memory pointer to another process to use.

As VladimirF already said, you cant use this message between processes, one way to do it is using Active Accessibility (http://www.microsoft.com/downloads/details.aspx?FamilyId=3755582A-A707-460A-BF21-1373316E13F0&displaylang=en), you can download the AccExplorer and use it to see the data in task manager ;)

Cheers

Thanks for u'r replys,
yaa it seems that my structure has some prob,coz i checked my application with a test application containing list control and that is also crashing.

but i couldn't figure out the prob

here is my code,

LVFINDINFO aInfoStruct;
ZeroMemory(&aInfoStruct, sizeof(LVFINDINFO));

aInfoStruct.flags = LVFI_STRING;
aInfoStruct.psz = (LPCTSTR)"XYZ.exe";

int index = ::SendMessage(hWnd,LVM_FINDITEM,(WPARAM)-1,(LPARAM)(const LV_FINDINFO FAR *)&aInfoStruct);



can u help me

thanx in advance
