ya i have gone through some applications in that,but no use.Now i have decided to attach a menu to the tree items.It consists of copy and paste menu items.When i copy a tree item from tree contol and pasting it on the explorer it is working.Similaly when i copy from explorer and paste it in the tree control it is not occuring.I have written the code like this.Is there any wrong in this.
void CTreeFileCtrl::OnTreefilectrlPaste()
{
COleDataObject DataObject;
if( DataObject.AttachClipboard() )
{
DataObjectToTree(&DataObject);
}
}
void CTreeFileCtrl::OnUpdateTreefilectrlPaste(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here
COleDataObject odj;
pCmdUI->Enable(FALSE);
if( odj.AttachClipboard() )
{
if( odj.IsDataAvailable( CF_HDROP ) )
{
pCmdUI->Enable(TRUE);
}
}
}
void CTreeFileCtrl::OnTreefilectrlCopy()
{
// TODO: Add your command handler code here
FileNamesToClipBoard();
}
void CTreeFileCtrl::OnUpdateTreefilectrlCopy(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here
HTREEITEM hItem = GetSelectedItem();
if(hItem){
pCmdUI->Enable(TRUE);
}
else{
pCmdUI->Enable(FALSE);
}
}
void CTreeFileCtrl::FileNamesToClipBoard()
{
CDropFiles DropFiles;
if(!PrepareFileBuff(DropFiles)){
return;
}
if (OpenClipboard())
{
BeginWaitCursor();
::EmptyClipboard();
HGLOBAL hMem = ::GlobalAlloc(GMEM_ZEROINIT|GMEM_MOVEABLE|GMEM_DDESHARE, DropFiles.GetBuffSize());
memcpy( (char*)::GlobalLock(hMem), DropFiles.GetBuffer(), DropFiles.GetBuffSize() );
::SetClipboardData (CF_HDROP, hMem );
::CloseClipboard();
EndWaitCursor();
}
}
BOOL CTreeFileCtrl::PrepareFileBuff(CDropFiles &DropFiles) const
{
HTREEITEM hItem = GetSelectedItem();
if( hItem == NULL){
return FALSE;
}
else if(hItem) {
//int index = mylist.GetNextSelectedItem(pos);
DropFiles.AddFile(ItemToPath(hItem));
}

I cant check you code but I see it seems it doesnt problem and I think I saw a loop(while) in your code for most a file and I think structure of your code is ok

i want to record the image screen behind one dialog,
when Pessing the OK button, this dialog don't disappear at once,and delay a while, sometimes my program may record this dialog's image, which covered
real image behind. why ?
here is my function:
void RecordScreen()
{
CMyDialog dlg;
if (dlg.DoModal()==IDOK)
{
//only click ok button to exit
RecordRectScreen(); //sometimes it records dlg'background
//this may cover the image screen in demand
}
}
void CMyDialog::OnOK()
{
....
BOOL aa = this->RedrawWindow(); //check aa , is true
CDialog::OnOK();
}

Did you search on codeproject I think I saw an article of course output of that program is a avi file
|
|

RedrawWindow(), this function has returned the value, but refreshing the action for the backgroud is not complete, the next function, RecordRectScreen() has executed,the bad thing happens.
thanks.

You can hide your program and keep it on sysem tray.

I am told that there is a better way to accomplish this task, but using bitwise operators to eliminate the need for the 3rd variable.
void switch_digits(short *numberOne, short *numberTwo)<br />
{<br />
short tempSwitch;<br />
<br />
tempSwitch = *numberOne;<br />
*numberOne = *numberTwo;<br />
*numberTwo = tempSwitch;<br />
}
How is it done?
|
|
|
|
|
a = a^b;
b = a^b;
a = a^b;
and I wouldn't do this unless there was a very good reason to

Hi all,
I have developed a windows service which runs executable files received from
some remote machine. Now i dont want to give my service all the rights so i
decided to run the service in "NT AUTHORITY\\LocalService" Account... but
when i do that i am unable to create any files or destroy any files in the
system
Now i want mmy service to have capability of creating new files but it shud
not be able to destroy any pre-exisiting files....also if possible i want to
restrict this file creation to only one particulat folder....meaning for e.g
if i have a folder called p2p then any excutable ran frm my service shud be
able to create files in that folder only and not in any other folder like
program files etc.
How do i achieve the above thing
thanks

I have project on hand where i have to lock all the exes on the client machine except the one exe that is to be retieved from the server database.This exe will be unlocked for a particular duration of time after that it has to be locked depending on its time duration.

Hello everyone!
OK, I have a dialog with many checkboxes, buttons, radios, listboxes, edits, and all that stuff... Each item is an option for the saved file that the program generates... Is there an easy way to add an event handler for the form itself so that on every change the Saved variable gets set to 0? Thanks!

I do not if it standard or not, but what I do is generate a checksum of all the controls on the dialog and then I check that checksum in the idle handler. If the checksum changes then I know that the user has made a change. If the checksum reverts back to the saved value then I know that the user undid the changes.

Interesting approach...! I have done something similar before so I though I would ask to be sure: Do you really generate a checksum, or do you do something like associate a particuar value to each control (like a bit-value that can be combined) and then check the value that way (that is what I did).
Peace!

If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Erm... Explain to the noob how to do it, please?

If the form has only a radio buttons or checkboxes then I will use a bitmask, but if there are edit controls or combo boxes then I will use a CRC-32 checksum. It also depends on the number of controls on the form, with only a couple controls it is hardly worth the extra effort required.
