Re: Need help on how to create image on child window and have to move along with vertical scroll bar to my dialog box

The only thing I can think of is that the scroll-bar offset is changing between the time that you assign a value to old_x and the time you use it, so it doesn't refer to the same position on screen at both points in time.

Aside from that, I'm sorry - I really can't help.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Heap corruption probelm when i try to return std::string from function in dll

Hi all,
I am working on vs2005 (vc++8).
I have created one dll in vs2005(vc++8), in that we have one function which returns "std::string" .

when i load this dll in another vs2005(vc++8) application and call the function which returns "std::string",
we get following error:

Windows has triggered a breakpoint in vstestdll.exe.

This may be due to a corruption of the heap, and indicates a bug in vstestdll.exe or any of the DLLs it has loaded.

The output window may have more diagnostic information

For more detail code is as follows:
[code]
dll function :

std::string getDH1(int clo)

{

return std::string("abcdefghijklmnopqr");

}

.exe code:

#define TEST2_API __declspec(dllimport);

TEST2_API std::string getDH1(int clo);

int _tmain(int argc, _TCHAR* argv[])

{

string sam =getDH1(1);

return 0;

}
[/code]

Does your code use a static library version of the C runtime? If so, then this sort of error is quite likely, as the EXE and DLL have different C heaps, so when the std::string is destructed, the EXE is trying to free memory in the DLL's heap, which is bad.

Look in Project Properties, C/C++->Code Generation, Runtime Library option.

How to execute other programs at the given time?

I hope I can express the question with my poor english.
I wanna write a dialog based program, and let user to set the time and at the given time, execute other programs(the user gives the exe file path).
Can give some code hint or source code like this?
Or a program in sourceforge having such function issue.

Hello,

This is the code iam using to display the tree.

HTREEITEM hItemRootVAL ;
HTREEITEM hItemParentVAL ;
HTREEITEM hItemSubVAL ;
HTREEITEM hItemTableVAL;
CString str;

hItemRootVAL = m_treePSISIInfo.InsertItem("PROGRAM",2,4, TVI_ROOT);
hItemParentVAL = m_treePSISIInfo.GetNextItem(hItemRootVAL, TVGN_CARET);
if(hItemParentVAL == NULL)
{

hItemParentVAL= m_treePSISIInfo.InsertItem("ONE",1,1,hItemRootVAL);
hItemSubVAL = m_treePSISIInfo.GetNextItem(hItemParentVAL, TVGN_CARET);
if(hItemSubVAL == NULL)
{
hItemSubVAL = m_treePSISIInfo.InsertItem("Table",0,0,hItemParentVAL);
hItemTableVAL = m_treePSISIInfo.GetNextItem(hItemSubVAL, TVGN_CARET);
if(hItemTableVAL == NULL)
{
str.Format("Table value 1 = 0x%02d",value1);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 2 = %d",value2);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 3 = 0x%04x",value3);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 4 = %d",value4);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 5 = %d",value5);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 6 = %d",value6);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
str.Format("Table value 7 = %d",value7);
hItemTableVAL = m_treePSISIInfo.InsertItem(str,3,3,hItemSubVAL);
}
}

Actually in this code value1,value2........up to value7.frequently these values change at runtime. when ever these values got changed i need to update those values with out collpsing the tree.please help me how to do.

Regards ,
Angel.

And you delete all the items in the tree and insert them again every time there is a change? If so, rather than rebuilding the whole tree all the time, use CTreeCtrl::SetItemText[^] to change the text in the tree, this should leave the expanded-collapsed states untouched.

What about making a note of which node is open, do the update, and then open that node back up afterwards?

nope, the standard menu don't support this.

but using owner drawn menus wouldn't be too hard if using an all made class...

Keyboard State - is ANY key pressed?

goop005-Feb-09 0:34

goop00

5-Feb-09 0:34

Is there a WIN32 function that will tell me whether any modifier key is pressed?

The context is a mouse hook function that is only interested if one or more modifier keys (shift, ctrl, alt) is pressed. If no key is pressed it just passes the event to the next hook.

I know that GetKeyState() returns the state of a specified virtual key, and that GetKeyboardState() returns an array of states. But a function that just tells me if ANY modifier key is pressed would add less latency in cases (most of the time) when a key is not pressed.

Thanks for listening Smile | :)
