No.
But I did consider that perhaps I should always use TCHAR when working with Windows stuff like writing registry keys, and sending setting window text.
I change my code to this, and I'm still working with WCHAR on szStatusMessage. The code is inside the IBindStatusCallback in the OnProgress Loop in case your wondering. For me this is uncharted waters, and I sort had to guess at how to work with it.
dBytes = ((float)ulProgress / (1024*1024));
dTotal = ((float)ulProgressMax / (1024*1024));
dPercent = dBytes/dTotal*100;
if ((dBytes > 0.10) && (dTotal > 0.10)) {
swprintf_s(szStatusMessage, L"Downloading %.2f MB of %.2f MB [%.1f%%]", dBytes, dTotal, dPercent);
iMsgLen = wcslen(szStatusMessage);
szStatusMessage[iMsgLen] = '\0';
}

I took it out, and put it back in.
I wasn't sure how to handle the callback loop, and didn't want to create what I call variables in the loop. So I created the szStatusMessage in the private section of the class. When the loop goes round, some of the messages are longer than others, and the old message doesn't clear when the new message is written to the space, so I put the \0 back in just to get rid of the old message, so the cat writes the entire space. I could experiment with moving it back into the loop, and see what changes I need to make.

You are misusing swprintf_s(). The second argument is the maximum number of characters to store in the buffer. Correctly used, swprintf_s() will terminate the buffer where necessary.
Try:
swprintf_s(szStatusMessage, sizeof(szStatusMessage), L"Downloading %.2f MB of %.2f MB [%.1f%%]", dBytes, dTotal, dPercent);

Let me look into the proper use, I know there was a ms version wsprintf_s and a ansi version swprintf_s. I moved the variables inside the loop, works ok, but I get squares in the message because I haven't populated it yet.
I guess I should of shown more code, the other half of the if statement, that shows the status message from the callback. I may kill the idea of that message, I don't see anything relevant to it.
if ((dBytes > 0.10) && (dTotal > 0.10)) {
swprintf_s(szStatusMessage, L"Downloading %.2f MB of %.2f MB [%.1f%%]", dBytes, dTotal, dPercent);
iMsgLen = wcslen(szStatusMessage);
szStatusMessage[iMsgLen] = '\0';
}
else {
if (wszStatusText != NULL) {
int iStatusLen = wcslen(wszStatusText);
if (iStatusLen < 80) {
iMsgLen = wcslen(szStatusMessage);
wcsncpy_s(szStatusMessage, wszStatusText, iStatusLen);
szStatusMessage[iStatusLen] = '\0';
}
}
}
SetWindowText(hWnd_Progress_Text, szStatusMessage);
dPB = (float)ulProgress/ulProgressMax*5000.0;
SendMessage(hWnd_Progress_Bar, PBM_SETRANGE, 0, MAKELPARAM(0, 5000));
SendMessage(hWnd_Progress_Bar, PBM_SETPOS, (WPARAM)dPB, 0);

Thanks for the heads up on the swprintf_s. I appreciate the attention to detail and efficiency you gave me today. tough learn today, but it works well.
Changed it to this now.
case BINDSTATUS_DOWNLOADINGDATA:
dBytes = ((float)ulProgress / (1024*1024));
dTotal = ((float)ulProgressMax / (1024*1024));
dPercent = dBytes/dTotal*100;
if ((dBytes > 0.10) && (dTotal > 0.10)) {
swprintf_s(szStatusMessage, 80, L"Downloading %.2f MB of %.2f MB [%.1f%%]", dBytes, dTotal, dPercent);
iMsgLen = wcslen(szStatusMessage);
szStatusMessage[iMsgLen] = '\0';
}
break;

wcslen() relies upon szStatusMessage being \0 terminated, so these two statements don't do anything useful.

I didn't know that. I'll experiment with removing them and see what happens. I'm sure your right on that. That means less code to type for me in the future.
Thanks Dave,

I used swprintf, I think the wsprintf was for tchars. It will do for now
WCHAR szBytes[20];
WCHAR szTotal[20];
swprintf(szBytes, L"%.2f", dBytes);
swprintf(szTotal, L"%.2f", dTotal);

Alright I'm still learning here so don't laugh, but I was able to consolidate the whole thing into one swprintf_s, to produce my status message. That's pretty cool. I wonder if I should of just used TCHAR and wsprintf_s and went the Microsoft way?
FYI:
I started with vb, so I was use to building strings together with &, or + in JavaScript.
dBytes = ((float)ulProgress / (1024*1024));
dTotal = ((float)ulProgressMax / (1024*1024));
if ((dBytes > 0.10) && (dTotal > 0.10)) {
swprintf_s(szStatusMessage, L"Downloading %.2f MB of %.2f MB", dBytes, dTotal);
iMsgLen = wcslen(szStatusMessage);
szStatusMessage[iMsgLen] = '\0';
}

You can still do that with MFC's CString class, or with the STL's std::string class.

I got few of these linker errors in my application.
I have reloaded the VC 6.0 - no SP packs yet and build a simple MFC ( all defaults) application and now I am getting same linker error.
I have not changed anything, using default setting.
I am guessing some library got "corrupted", but which one?
Any clue what is happening here?
Linking...
ChildFrm.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall CWnd::SetOccDialogInfo(struct _AFX_OCC_DIALOG_INFO *)" (?SetOccDialogInfo@CWnd@@UAEHPAU_AFX_OCC_DIALOG_INFO@@@Z)

Debug/TSET2.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Any help as always will be appreciated. Thanks for your time.
Addendum
Dialog based MFC application compiles just peachy, only SDI and MDI have this linker issue.

After flushing and reinstalling the VC 6.0 from scratch it works.

Are you sure that function (SetOccDialogInfo) is available in this version of MFC (VS 6.0?)
The difficult we do right away...
...the impossible takes slightly longer.

I have been using VC 6.0 for at least 15 years and this is the first time I encountered this linker error.
I am going for full reinstall of the VC 6.0 for now.

Hi,
I have an app that has two tab, "informes" and "variables", but I have to delete the informes tab becouse now it is not used. The code isn't me, and due to it, I don't know how to delete the tab.
This is the app.
http://i42.tinypic.com/2bwfiu.png
I think that the tab is created in Ftab file, but I dont know where.

As read in FTab.cpp/.h

I'd guess that the 'informes' tab is created(added to the list of tabs) with CFolderTabCtrl::AddItem or perhaps they're all loaded at once from a resource, via the CFolderTabCtrl::Load method.
If you have the source, I'd simply search for 'informes' - I'd check the resources too.
Failing that - if you have a debug build, I'd get Ida Pro Advanced (you can get a free-version) and analyse the exe file, looking for either (a) references to the string 'informes' or (b) references to any/all functions in the CFolderTabCtrl class.

Is this a property sheet/page arrangement? Have you checked the sheet's constructor?

Yes I cheked, and I think that here there aren't any to indicate the number of tab.
In " AdestView.cpp" there is a function that call one function of this file:
[code]
void CAdestView::OnUpdate(CView* , LPARAM , CObject* )
{
........
....
...
if (!m_wndFolderTab.GetItemCount ())
{
m_wndFolderTab.CreateFromStatic (IDC_FOLDERTAB, this);
m_wndFolderTab.Load (IDR_FOLDERTABS);
f = m_Lista.GetFont ();
m_wndFolderTab.SetFonts (f,f);
}
...
...
[/code]
But I don't know how to create only one tab and not two

Have you looked for the IDR_FOLDERTABS resource (which I think is a newline-separated list of tab names)?

Hi,
I´m searching for the best way, to define some kind of as function alias in C++
I have the following class:
class c1
{
private:
CString FunctionWithADisturbingLongName(int i);
}
And i want the function to have the long function name, because the function of the function has to be explained in it  .
But I want to have a shortcut to the function.
I want to do this
c1 test;
test.short_1(1);
instead of
c1 test;
test.FunctionWithADisturbingLongName(1);
Of course I could declare and define short_1 as a member of c1, and then call FunctionWithADisturbingLongName in it, but there has to be a better solution.
Thank you for helping!

|
|
|

#define FunctionWithADisturbingLongName test
That might do the trick as well.

That would probably work... although this might make debugging a bit of a pain.
