Re: If my main dialog is minimized, how can I flash on taskbar to notify the user that my program wants attention?

Maybe try using FlashWindow[^] or FlashWindowEx[^], however i am not sure how these work for a minimized window.

Shouldn't I use SetForegroundWindow? Anyway, I posted the question again, with some more details at http://www.codeproject.com/Forums/1647/C-Cplusplus-MFC.aspx?fid=1647&select=3070075&tid=3070075[^]

Hi,

For book recommendations, see here[^]. I am assuming that you have working knowledge of Win32 and a good understanding of the object oriented programming paradigm. Those two will help you in learning MFC faster.

Happy learning. Smile | :)

CMFCRibbonComboBox Not Enabled -

I'm using VS 2008 with the new MFC framework and ribbon UI.   I'm working on a hobby project, and am trying to add a combobox to one of the ribbon tab/panels.   It appears - and shows the first item of text added, but it is not "enabled".   It's light grey as though it's not enabled and clicking does nothing, although when I mouse over the rest of the panel, the panel itself lights up correctly.

bNameValid = strTemp.LoadString(IDS_RIBBON_PORT_SELECT_BOX);
     ASSERT(bNameValid);
     CMFCRibbonComboBox* pSerialPortSelectBox = new CMFCRibbonComboBox(ID_RIBBON_PORT_SELECT_BOX, TRUE, 80, strTemp, 1);

     pSerialPortSelectBox->AddItem(_T("Test"));
     pSerialPortSelectBox->AddItem(_T("Test2"));
     pSerialPortSelectBox->AddItem(_T("Test3"));
     pSerialPortSelectBox->AddItem(_T("Test4"));

     pSerialPortSelectBox->SelectItem(1);
     pSerialPortSelectBox->EnableDropDownListResize(TRUE);
     pPanelSerialConfig->Add(pSerialPortSelectBox);

This shows "Test2" sitting in the box, but the whole thing is greyed out.

Any thoughts?

You should add a message handler for it.

Probably as defined by the TMP or TEMP environment variable?

vikrams wrote:

What time-out? A compression operation won't time-out. The underlying file access operations might, if they're (for example) network operations, but not the compression operation.

My TMP env vars points to system32\temp and localsettings\temp

Actually it creates the temp file at the same location of the requested file for compression Frown | :(

How Can I build an Array of Arrays?

How Can I build an Array of Arrays?

5-Jun-09 2:51

Hi I asked this before, but didn't get a clear answer. How can I build an array of CObArray arrays? In other words, I need it to work like a stack, so I can add CObArrays to the stack, and retrieve an Array based on an index?

Thanks

Even though you asked this same question three minutes ago, have you tried:

CArray<CObArray, CObArray&> arr;

Isn't this where I would run into Copy assignment problems?

5-Jun-09 2:58

Doesn't this work:

CObArray my_array;
my_array.Add(new CObArray);
my_array.Add(new CObArray);
...
((CObArray *)my_array.GetAt(0))->Add(...);
...

I think I had something similar which didn't work;

CObArray array1;
CObArray array2;  
.....
//Add
array2.Add(&array1);
......
//Read Array at index 2
CObArray RetrieveArray;
RetrieveArray.Copy( *(CObArray *)array2.GetAt(2));

For instance,

for(int i=0; i< 3; i++){
if(i==0)
   array2.add(&a);
if(i==1)
   array2.add(&b)
if(i==2)
   array2.add(&c)
}

RetrieveArray.Copy( *(CObArray*)array2.GetAt(0)); ////Comes back with array c
RetrieveArray.Copy( *(CObArray*)array2.GetAt(1)); ////Comes back with array c also

it seems to always come back with the last array no matter what I do! arra2.GetSize() = 3, which is right.

Code-o-mat5-Jun-09 3:45

5-Jun-09 3:45

I did a very simple experiment and it worked fine for me:

CString as("as"), bs("bs"), cs("cs");
CObArray array2, a, b, c;
a.Add((CObject*)&as);
b.Add((CObject*)&bs);
c.Add((CObject*)&cs);
for(int i=0; i< 3; i++)
{
  if(i==0)
    array2.Add(&a);
  if(i==1)
    array2.Add(&b);
  if(i==2)
    array2.Add(&c);
}

CObArray aRetrieveArray, bRetrieveArray, cRetrieveArray;
aRetrieveArray.Copy( *(CObArray*)array2.GetAt(0));
bRetrieveArray.Copy( *(CObArray*)array2.GetAt(1));
cRetrieveArray.Copy( *(CObArray*)array2.GetAt(2));

CString *astr = (CString *)aRetrieveArray.GetAt(0);
CString *bstr = (CString *)bRetrieveArray.GetAt(0);
CString *cstr = (CString *)cRetrieveArray.GetAt(0);

AfxMessageBox((*astr) + _T("\n") + (*bstr) + _T("\n") + (*cstr));

Maybe i am not getting your point.
