I need this dialog a Modal dialog box.
I have set the System Modal property to FALSE.
|
|
|
|
|
If using MFC, call the DoModal method, otherwise call the DialogBox macro.

Still my dialog window is not Modal..
I have done this :
m_HPCRWODlg.Create(this->m_hWnd);
m_HPCRWODlg.DoModal();
Please help..

why do you have to use create function?
just give this
m_HPCRWODlg.DoModal();
in your button. It should work.

Hi,
Based on the value 'SELECTED' I am trying to do some statements.
The following code doesnt work for the two values of 'SELECTED'.
typedef enum{
APPLE =0,
ORANGE =1
}FRUITS;
#define SELECTED APPLE
#if SELECTED == 1
AfxMessageBox("orange");
#else
AfxMessageBox("apple");
#endif
Kindly help.

#if is a pre-processor directive processed by the preprocessor and enum and AfxMessageBox are handled by the compiler. You cannot mix them this way. What is it that you're trying to do here?

Tell me one thing if I replace enum with #define and instead of AfxMessageBox, I define varA, then it compiles.
#define APPLE 0
#define ORANGE 1
#define SELECTED APPLE
#if SELECTED == 1
int varA = 100;
#else
int varA = 101;
#endif
Replacing enum with #define is fine but isn't the definition of varA also handled by compiler only?
I mean why int varA = 101; is ok and AfxMessageBox not?

I bet you have put that globally. I mean outside of all functions.
You cannot call a function globally unless you are assigning to a variable.
Try this.
#if SELECTED == 1
int varA = AfxMessageBox(L"Selected");
#else
int varA = AfxMessageBox(L"Not Selected");
#endif

Yeah! u r correct!
But why so?
I mean why is it ok if I assign it to an int and not otherwise?
|

It isn't about a function call actually.
It is about initializing a global variable even if it means calling a function to do it.
So we can use that trick to execute a function even before the entry point of a program.

#define APPLE 0
#define ORANGE 1
int varA = 0;
#define APPLE_DEFINED
#ifdef APPLE_DEFINED
varA = 100;
#else if ORANGE_DEFINED
varA = 101;
#else if PAPAYA_DEFINED
varA = 102;
#endif //APPLE_DEFINED

As you've heard you can't do that. In the above line APPLE is not defined so SELECTED remains undefined so you always get

You can only use
#define APPLE 0
#define ORANGE 1

Is your problem for displaying the toolbar on the dialog or you have already done it and then problem is with the display of the image on the toolbar?

Sorry to trouble you guys, but I think I'm missing something in my understanding of the List Control boxes.
I'm creating a CListCtrl box with 3 columns. The first 2 are text and the third will show bitmaps. My code goes like this:
void PopulateList ()
{
LVCOLUMN lvColumn1,lvColumn2,lvColumn3;
COLORREF rgbMask = RGB(0,0,0);
CImageList ThumbList;
ThumbList.Create(MAXWIDTH, MAXHEIGHT, ILC_COLOR, 1, 1);
lvColumn1.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
lvColumn1.fmt = Alignment;
lvColumn1.cx = 120;
lvColumn1.pszText = ColumnHeading[0];
nCol = m_MainList.InsertColumn(0, &lvColumn1);
int NextIndex = nCol;
while (!EOF)
{
.
.
LVITEM lvItem;
lvItem.mask = LVIF_TEXT;
lvItem.iItem = NextIndex;
lvItem.iSubItem = 0;
lvItem.pszText = OutputTitle;
NextIndex = m_MainList.InsertItem(&lvItem);
.
}
ListView_SortItemsEx( m_MainList.m_hWnd, CompareProc, (LPARAM)&m_MainList );
lvColumn2.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
lvColumn2.fmt = Alignment;
lvColumn2.cx = 120;
lvColumn2.pszText = ColumnHeading[1];
nCol = m_MainList.InsertColumn(1, &lvColumn2);
int NumOfEntries = m_MainList.GetItemCount();
for(int i=0; i>NumOfEntries; i++)
{
.
.
.
m_MainList.SetItemText(i,1, <Data>);
}
lvColumn3.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
lvColumn3.fmt = Alignment;
lvColumn3.cx = 240;
lvColumn3.pszText = ColumnHeading[2];
nCol = m_MainList.InsertColumn(2, &lvColumn3);
NextIndex = nCol;
BYTE PreviewInfo[MAXHEIGHT][MAXWIDTH][3]={0};
int ImageIndex = 0;
for(int i=0; i<NumOfEntries; i++)
{
BOOL ValidPicture = ReadDataFromDataFile(.....);
if(ValidPicture)
{
HBITMAP Picture = <Data Read>
CBitmap *ThumbNail = new CBitmap;
ThumbNail->Attach(Picture );
ImageIndex = ThumbList.Add(ThumbNail,rgbMask);
m_MainList.SetImageList(&ThumbList, LVSIL_SMALL);
LVITEM lvItem;
lvItem.mask = LVIF_IMAGE;
lvItem.iItem = i;
lvItem.iSubItem = 0;
lvItem.iImage = ImageIndex;
NextIndex = m_MainList.InsertItem(&lvItem);
delete ThumbNail;
}
else NextIndex++;
}
}
m_MainList is the handle to the CListCtrl on the dialog
If I don't code in the Column 3 code, I get my first 2 columns ok. Once I do put in the Column 3 code, Column 1 data all disappears and Column 3 also has no data.
I believe the problem is in my declaration of the CImageList and how I am putting it into the Column, but I don't know what is wrong and also why Column 1 is being affected.
Can someone point me in the right direction here?

Try changing that line to
lvItem.iSubItem = nCol; ?
