Hi. Ive got a simple Visual C++ application (non-managed; Visual C++ version 7). I need a folder-tree control that lets the user search thru the folder tree, then select a single folder. I dont need anything fancy (such as multiple selections, etc). Also, I cant use anything that relies on recent Visual C++ features because I've got an older version. I dont need to fill the tree with my own custom data: I just want the tree software to automatically populate the tree from the disk drive (based on soom root folder I give it). I looked at the list of Tree Controls at:
http://www.codeproject.com/KB/tree
but it is a bit overwhelming. Can anyone suggest a tree control that is simple, mature, and works with Vis C++ version 7?
Thanks in advance.

We have a medical imaging application. Recently one our processes crashes after a particular workflow and from the user.dmp thus created its getting extremely difficult to trace down the issue. Its not always that the process crashes after this workflow. But rarely it does and thats what giving half the team sleepless nights.. Am attaching below the callstack which I am getting. Any leads on this would be highly appreciated. Thanks in advance.

good for you,
you probably need to check CChannelHandle or ClientGetBuffer

None of what you see in the callstack are my functions. Its all from ole32.dll

I wonder how can I change text alignment of an edit control in runtime? I googled for some minutes, but I caught nothing ...
Any information or link or something?
Thank you masters!
|
|
|
|
|
Have you tried ModifyStyle and passing ES_RIGHT, ES_CENTER, or ES_LEFT to it ?
|
|
|
|
|
AFAIK there's no way, unless you subclass the control.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

According to the docs, the alignment styles cannot be changed
after the control is created.

I created my own GUI, straight forward region box with a loaded bitmap,
i have question about setting a menu up for it, because menus sit under the title bar and atm its my own gui would i have to program my own menu or is there a way to move it down and resize it

yes.
I you create your own UI, you must be prepared to go all the way...
BUT, I've seen applications with custom UI that still use standard menubar and menu, and only show the menu on demand,
when the user's mouse pointer gets near where the menu should be.
|
|
|
|
|
so im wondering whether they created a GUI as a frame and stuck a frameless window in there which had the menu at the top maybe

I have a mask DC (dcFrom) that I want to rotate into another DC (dcTo);
Both DCs are monochrome. For example, dcFrom is all black, with a white ellipsed in the middle(ish).
I make a new DC, and set it all black. I do a PlgBlt, and I end up with a white circle in a black rectangle - but I also end up with some odd white artefacts around the edge.
Has anyone used PlgBlt with monochrome DCs before?
BOOL b = ::PlgBlt (*m_pDC, ptCorners, *pDCTmp, boundsOld.Shape.left - boundsOld.DC.left, boundsOld.Shape.top - boundsOld.DC.top, boundsOld.Shape.Width (), boundsOld.Shape.Height (), NULL, 0,0);

Grrr me.
Had a flash of inspiration, and setting Text and Bk colours cured it.
m_pDC->SetTextColor (RGB(0,0,0));
m_pDC->SetBkColor (RGB(255,255,255));
pDCTmp->SetTextColor (RGB(0,0,0));
pDCTmp->SetBkColor (RGB(255,255,255));
BOOL b = ::PlgBlt (*m_pDC, ptCorners, *pDCTmp, boundsOld.Shape.left - boundsOld.DC.left, boundsOld.Shape.top - boundsOld.DC.top, boundsOld.Shape.Width (), boundsOld.Shape.Height (), NULL, 0,0);

Hello,
I'm Giulio an Italian new MFC developer. I have a problem with the class CMFCPropertyGridProperty. I want to use the Color Palette generated by this class to retrieve a color value to use in my Drawcli like application. This is the code I write (this code is automatically generated by mfc wizard):
void CPropertiesWnd::InitPropList()
{
...
CMFCPropertyGridColorProperty* pColorProp = new CMFCPropertyGridColorProperty(_T
("Colore della finestra"), RGB(210, 192, 254), NULL, _T("Specifica il colore predefinito della finestra."));
pColorProp->EnableOtherButton(_T("Altro..."));
pColorProp->EnableAutomaticButton(_T("Predefinito"), ::GetSysColor(COLOR_3DFACE));
pGroup3->AddSubItem(pColorProp);
...
}
I want to use the color value retrieved by this menu as I can do with a dialog control. Could anyone help me?

Hi
Using the MS Example "How to create an automation project using MFC and a type library" to control MS Excel under MFC I get the error
Excel::_Application cannot instantiate abstract class
using the following code
void CAutoProjectDlg::OnRun()<br />
{<br />
_Application app;
<br />
if(!app.CreateDispatch("Excel.Application"))<br />
{<br />
AfxMessageBox("Couldn't start Excel.");<br />
}<br />
else<br />
{<br />
app.SetVisible(TRUE);<br />
AfxMessageBox ("Excel is Running!");<br />
}<br />
}<br />
How should I overcome this error ?
Regards,
sdancer75

Well, the error gives you a lot of information.
I'm assuming _Application is the Excel interface. An interface is pretty much just a C++ class with all the methods abstract. So you can't create it directly.
I suggest you search for examples, and look for CoCreateInstance, or CoCreateInstanceEx.
Under Platforms, Frameworks & Libraries on CP, there is a COM category - there are several good tutorials there. They may not clue you in on excel, but they will give you the COM concepts you need.
Iain.
