I agree, it's not something that should normally be done. After all, what the hell are DLL's there for?
Another way I know of is to build a type library for the exe and add the export into it, again though, what's the point?

Sure?
How can you do that?

How to use large cursor as in PhotoShop?
As I know, cursor size is maximum to 32x32 pixels.
Pens in PhotoShop use very large cursors, how to do that?
|
|
|
|
|
Don't use a cursor, instead use a bitmap and draw it to the cursors location.
|
|
|
|
|
|
Take a look at this[^]. I used depends.exe and it seems that all they do is draw transparent bitmaps.

I have this line of code :
TargetList.push_back(CSTREAMS(*(SrcList[i])));
where CSTREAMS is a userdefined class and TargetList is a vector. So i'm just calling the constructor without the new keyword. I think this creates a temporary object, wich is copied by the vector and then destroeyd, so no memoryleak. Is this correct ?

Hi all,
I've written an MFC MDI application where I need an additional child frame to show other aspects of my data. So I derived a class from CMDIChildWnd and created the Icon, Accelerator and Menu. My view for this child frame is derived from CFormView and has a chart control an a button control.
I call/create the child frame by choosing a menu entry as follows:
<br />
void CmyApp::OnAnsichtnewView()<br />
{<br />
CMainFrame *pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd);<br />
pFrame->CreateNewChild(RUNTIME_CLASS(CmyChildFrm), IDR_myTYPE);<br />
<br />
CRect cr;<br />
pFrame->GetActiveFrame()->GetClientRect(cr);<br />
<br />
CDocument *pDoc = pFrame->GetActiveDocument();<br />
CRuntimeClass *pRTC = RUNTIME_CLASS(CmyFromView);<br />
CCreateContext context;<br />
context.m_pCurrentDoc = pDoc;<br />
context.m_pNewViewClass = pRTC;<br />
context.m_pLastView = NULL;<br />
<br />
pFrame->GetActiveFrame()->CreateView(&context);<br />
}<br />
In my view class I've overwritten the OnSize method as follows:
<br />
void CmyFormView::OnSize(UINT nType, int cx, int cy)<br />
{<br />
CFormView::OnSize(nType, cx, cy);<br />
<br />
if(m_Chart.GetSafeHwnd() != NULL)<br />
{<br />
m_Chart.MoveWindow(0, 0, cx-30, cy);<br />
AfxMessageBox("Chart resized");<br />
}<br />
if(m_Button.GetSafeHwnd())<br />
{<br />
m_Button.MoveWindow(cx-30, 0, 30, 30);<br />
AfxMessageBox("Button resized");<br />
}<br />
AfxMessageBox("Form resized");<br />
}<br />
When I run my programm and do a resize on my new child, I only get a "Form resized" MessageBox. So, obviously m_Chart and m_Button don't get a Hwnd but I don't know why.
Can anybody give me a hint on this?
Thanks,
Frank.

It seems your m_Button and m_Chart variables were not associated with child controls. Did you create your child controls with Create member, like m_Button.Create(. . .), or in a different way?
Maybe you should show us more details.
|
|
|
|

I used the dialog editor to create the controls. The chart control is an ActiveX control and the button is actually a checkbox control, which behaves like a button. In this editor I also assigned the member variables by a right click on the control and let the framework do the job. So the framework also created the DataExchange
void CmyFormView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TCHART_Chart, m_Chart);
DDX_Control(pDX, IDC_CHECK_Button, m_Button);
}
I created also another child frame in the same way but assigned it to a DocTemplate so that it starts when the programm start. Here I don't have resizing problems. So maybe I did something wrong in my OnAnsichtnewView part when the user creates the child frame. Maybe I have to pass a handle?
Thanks,
Frank.

Hi,
I have taken an ATL component and imported MSADO15.DLL to include ADO functionality
#import "C:\\Program Files\\Common Files\\System\\ADO\\MSADO15.DLL" rename_namespace("ADOCust") rename("EOF","EndOfFile")
using namespace ADOCust;
I referred to the following link.
http://www.codeproject.com/atl/atl_ado.asp?df=100&forumid=1749&fr=51[^]
The problem Iam facing is when I try to check EndOfFile attribute for the recordset pointer using
VARIANT vartemp;
vartemp.vt = VT_BOOL;
vartemp.boolVal = FALSE;
vartemp.boolVal = pRecordset->EndOfFile;// not getting the value as TRUE even if the recordset pointer is at the end
Is there any problem with renaming EOF to EndOfFile in import statement??
I have all other functionalities working well.
Any suggestions would be helpful.
Thanks

Hi,
Can someone please tell me how to export a CDialog based class from a MFC extention DLL. I saw tutorials showing how to do that. they work when i build them as they are told to. In the tutorial i found it exports a diffrent class and in that class the dialog box is shown. but it doesn't work in my case.
some one tell me how to export the CDialog class itself with the resource..

The easiest and safest way is to follow the MFC guidelines - Extension DLLs[^]
The most important things are the initialization of the DLL (AfxInitExtensionModule), the
declaration of your classes (adding AFX_EXT_CLASS), and using the global defines in the app and
DLL projects (_AFXDLL defined in the app, _AFXEXT defined in the DLL).

Hi, I am using WH_KEYBOARD_LL global hook to detect keystrokes in any window. Is there any way to get handle of a window that is related to key stroke or handle of the window in which I am writing? Thanks in advance.
|
|

|
|
I think you can call HWND GetActiveWindow(VOID) inside your HOOK PROC, but I NEVER made a test about it.

GetActiveWindow()<br />
GetForegroundWindow()<br />
GetFocus()<br />
You can use the above for that purpose.

Hi,
I need to display the available display resolution settings from monitor settigs not from display device driver.
I got the display device settings resolution by using EnumDisplaySettigs function.
Can anyone tell how to get the resolutions from Monitor?
I have tried to get Monitor Name from EnumDisplayDevices(API) and passed the same to EnumDisplaySettigns. Not Working|
awaiting your replies.

Hi,
The following code is not giving expected result for me.
I need display resolutions from the current monitor settings not from display device.
Problem is dispCurrent.DeviceName is not taken by the EnumDisplaySettings API.
Please tell me where i am going wrong.
int displayNumber=0;
DISPLAY_DEVICE dispDev, dispCurrent;
memset(&dispDev, 0, sizeof(dispDev));
memset(&dispCurrent, 0, sizeof(dispCurrent));
dispDev.cb = sizeof(DISPLAY_DEVICE);
dispCurrent.cb = sizeof(DISPLAY_DEVICE);
EnumDisplayDevices(NULL, displayNumber, &dispDev, 0);
while (EnumDisplayDevices(dispDev.DeviceName,displayNumber,&dispCurrent,0))
{
displayNumber++;
CString MonName = dispCurrent.DeviceName;
if ( (dispCurrent.StateFlags & DISPLAY_DEVICE_ATTACHED_TO_DESKTOP) == DISPLAY_DEVICE_ATTACHED_TO_DESKTOP)
{
// Get all modes and display them in a listbox
BOOL bRetVal;
CString sDevMode;
CString sDevModeCurr;
CString strRep = "x";
DEVMODE devmode;
DEVMODE devmodeCurr;
DWORD iMode =0;
do
{
bRetVal = EnumDisplaySettings((LPCTSTR)dispCurrent.DeviceName, iMode, &devmode);
iMode++;
if (bRetVal)
{
sDevMode.Format("%dx%d, %d bits %dhtz", devmode.dmPelsWidth,
devmode.dmPelsHeight, devmode.dmBitsPerPel,
devmode.dmDisplayFrequency);
m_sDispRes.AddString(sDevMode);
}
}
while(bRetVal);
}
}

Does anybody know if there is an auto build increaser in VC8? If so where and how is it configured?
In VC6 I used an add-in, but surely MS have updated a little since the dark ages.

Hi,
Sender:
- Establish Connection
- Send info what you're going to do, eg. copy file
- Open file
- read content
- send content
- close file
- Wait for acknowledge
- Shutdown transmission
- Liu out!
Recipient:
- Establish Connection
- wait for info
- create file (from info)
- receive content
- write content to file
- close file
- acknowledge completion
- Shutdown connection
Regards
|

Also, if using Windows Sockets, you can use the TransmitFile() API to do the "read content/send
content" steps mentioned by Galatei
