Hi, i have a variable of type float that get a return value thats greater than what float or double, long double etc can hold. The return data does not need to be so precise, example it holds 1.1520230e-007 when it overflows, and i really just need 1.1520230. However when the variable overflows like this i cant print it, i cant cast it or move it to a buffer. Is there a c\c++ function that truncates it, i have tried to cast the return data as type float but no success. Also i cant pass it to a buffer to then shorten it later as VS ignores the data except in the debug-watch window. Any ideas are much appreciated. Regards, Fred

Thanks, that made it work :)

Ok, how do i associate the menu to the dialog? The menu opens when right mouse button is pressed and so i dont care to attatch it to the Child Dialogs system menu.

Hi Mark, I call it via afx_msg void OnAddNewItem(); and ON_COMMAND(ID__ADDITEM, &CItemDlg::OnAddNewItem) Edit: the menu item is created via CMenu and if i move ON_COMMAND(ID__ADDITEM, &CItemDlg::OnAddNewItem) to the main dialog it works fine. But i want to know why i cant call it in the child dialog

Hi, for some reason i can only call ON_COMMAND in my main dialog, how can i call it in a child dialog? Any ideas would be much apreciated!

Perfect, just what i needed. Thanks!

The initial dialog does not paint when there is a modal dialog in focus, because i run the app in full screen. But if there are no functions that i can use that deals with "OnFocus", WM_PAINT works, i just need to be carefull with it. Thanks Fredrick

I have a question in regards to, if there is a built in function in mfc i can overload that gets called when a dialog is brought back to focus after a DoModal() operation. I end the modal dialog with OnOK(). the OnPaint() starts to paint again when its brought back to focus, but is there is a cleaner way to check for this event? Thanks

such as.... VERIFY(m_dlg1.Create(Main::IDD, this)); EDIT: the dialog is already drawn and past OnInitDialog, however i am using tabing so all dialogs are visible at the same time. -- modified at 18:20 Friday 30th March, 2007

I get an ASSERT(::IsWindow(m_hWnd)) when i try update a CEdit item in from another class like Myclass c; c.OnUpdate(); what do i need to do to solve this issue? Any sugestions appreciated.

I guess i did not test it fully, now that i know it should work i am sure il sort it out :)

I am creating a simple launcher for quake2 in mfc where i want to launch it with "quake2.exe +set maxclients 16" etc. I am only familiar with shellexecute, but i have problems launching anything with arguments, is there anything built in mfc or a c++ function i could use to launch with arguments? Thanks.

thanks, that solves it ;)

that gives me an error like this error C2664: '_beginthread' : cannot convert parameter 1 from 'void (__thiscall CGLMFCDlg::* )(void)' to 'void (__cdecl *)(void *)' 1> There is no context in which this conversion is possible

i try to start another thread with this code CGLMFCDlg * MyThread= new CGLMFCDlg; _beginthread(MyThread->Thread, 0,NULL); delete MyThread; the new thread is a void function, i get a error message as follows: error C3867: 'CGLMFCDlg::Thread': function call missing argument list; use '&CGLMFCDlg::Thread' to create a pointer to member Any sugestions on how i can solve this? thanks

yes, makes sence. thanks

I am curently loading a dll like this static HMODULE hMod ; hMod = LoadLibrary("Updater.dll");exit(1); if(!hMod) { AfxMessageBox("not found !!!!!"); exit(1); } FreeLibrary(hMod); The mfc app loads the mfc dll and exits, but is it possible to define some sort of return value in the mfc dll that the mfc app closes while the dll continue processing?

Hi Robert How do i focus it to the correct idc? i get an assert: { ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, EM_SETSEL, nStartChar, nEndChar); if (!bNoScroll) this is the code i have: void CAutoUpdaterDlg::OnUpdateScreen() { char LocalBuffer[10]; itter++; sprintf(LocalBuffer, "%d", itter); CEdit * p = static_cast(GetDlgItem(IDC_Window)); // static message for now if(!FilesInProgress) { strcat(WindowBuffer, LocalBuffer); strcat(WindowBuffer, ": "); } else strcat(WindowBuffer, ""); strcat(WindowBuffer, DynamicBuffer); int Size = strlen(WindowBuffer); p->SetMargins(5,5); p->SetWindowText(Convert_A_To_DA(WindowBuffer)); CProgressCtrl * progress = static_cast(GetDlgItem(IDC_PROGRESS)); progress->SetRange(0,MaxRange);Progress++; progress->SetPos(Progress); int MemSize = strlen(DynamicBuffer); for(int i = 0; i<= MemSize+1; i++) { DynamicBuffer[i] = 0x00; } CEdit myEdit; CString csContent = _T(Convert_A_To_DA(WindowBuffer)); myEdit.GetWindowText( csContent ); myEdit.SetSel( csContent.GetLength(), csContent.GetLength(), TRUE /* scroll to the selected text */ ); UpdateWindow(); FilesInProgress = false; }

I constantly add more data into a CEdit, i also activated the scroll bar for this window. When the text exceeds the CEdit text area limit, the scroll bar is activated so i can scroll the text up and down which is good. Though instead of that i have to scroll downwards to see the new text added, is there a CEdit function which tells the scroll bar to always stay at max, or point downwards? So i have to scroll upwards instead to see the old text. Thanks

UpdateWindow(); this function worked perfect, thanks.
