Hello, First, see the topic - 'How to ask Questions' in this forum. Second, you are missing lvi.iItem I think. Try adding this and see.
// Insert item for col 0
lvi.mask = LVIF_TEXT;
lvi.iItem = 0;
lvi.iSubItem = 0;
lvi.pszText = "one";
m_ListCtrl.InsertItem(&lvi);
// Insert subitem for col 1
lvi.pszText = "two";
lvi.iSubItem = 1;
m_ListCtrl.InsertItem(&lvi);

Hello everybody, I am trying to convert CString to float using atof(). but its not giving the exact value. for eg.
CString strVal;
GetDlgItem(IDC\_MAXLAYER)->GetWindowText(strVal);
float mVal = atof(strVal);
IDC_MAXLAYER is edit box and in that, i am having the value 386.080, but after atof() conversion, mVal shows 386.07999 is that possible to get exact 386.080 by converting? Thanks in advance. A. Gopinath.
Hello Everybody, I have created one SDI Application with one dialog - having some controls. In that, if I click a button, I want to show a child window and with the following code, I am getting that fine.
CMainFrame *pMainFrm = ((CMainFrame*)(AfxGetApp()->m_pMainWnd));
CFrameWnd *pFrame = new CFrameWnd;
RECT rect;
pFrame->Create(NULL,_T("Solution"), WS_OVERLAPPEDWINDOW ,rect,this);
pFrame->ModifyStyle(WS_CAPTION + WS_OVERLAPPEDWINDOW , WS_BORDER,SWP_NOMOVE +SWP_NOZORDER );
pFrame->InitialUpdateFrame(pMainFrm->GetActiveDocument(),TRUE);
pFrame->SetWindowPos(&CWnd::wndTopMost,100,200,1000,400,SWP\_SHOWWINDOW);
pFrame->ActivateFrame(SW\_SHOWNORMAL);
Now, I would like to write some text on that child window. Any suggestions? I tried in google also. Thanks in advance, A. Gopinath.
Hello Everybody, I am trying to pass some values to char ** (to a third party library). But i am getting some issue in that.
char\*\* ids = new char\*\[m\_Size\];
for(int i=0; i
using that third party function, its creating an output file and in that file the stored value is showing like this.
GROUP : 46,0
GROUP : 44,0
GROUP : 42,0
GROUP : ÝÝÝÝÝÝÝ݆«ãe,0
GROUP : 40,0
GROUP : 38,0
But if I give values like this, then in output file, the values are showing fine.
char* ids[6] = {"38", "40", "42", "44", "46", "48"};
in the output file,
GROUP : 38,0
GROUP : 40,0
GROUP : 42,0
GROUP : 44,0
GROUP : 46,0
GROUP : 48,0
(see the sequence also)
what i am doing wrong? initialization ? or passing values ?
Thanks,
A. Gopinath.
Hello, Since you set the property to Unicode Character Set, you can try like this.
CString fileName = L"c:\\\\1.bin";
CT2CA filen(fileName);
fopen(filen,"wb");
Hope this helps. Regards, A. Gopinath.
Hello Richard, I debug the whole code by putting breakpoints in all the functions, after closing the dialog, its not going anywhere in the code, remains on the application itself. I am attaching the code herewith. Please download and check. http://www.4shared.com/zip/eDwcyehu/SDITest.html[^] Thanks.
Thanks for you reply. Actually, I created one MFC Application using the Template, and its SDI. So, it creates list of files, Doc, View, etc. For View, i select the base class as CView (in the wizard itself). I removed the default created menu and included my menu list. Now, i added a simple dialog, and for that, I created a class also derived from CDialog. Following are the .h and .cpp file contents .h file
class CSelectOptionsDlg : public CDialog
{
public:
CSelectOptionsDlg(CWnd* pParent = NULL);
virtual BOOL OnInitDialog();
public:
enum {IDD = IDD_SELECTOPTIONSDLG};
public:
void OnOkClicked();
DECLARE\_MESSAGE\_MAP()
};
.cpp
CSelectOptionsDlg::CSelectOptionsDlg(CWnd* pParent)
: CDialog(CSelectOptionsDlg::IDD, pParent)
{
}
BEGIN_MESSAGE_MAP(CSelectOptionsDlg, CDialog)
ON\_COMMAND(IDOK, OnOkClicked)
END_MESSAGE_MAP()
void CSelectOptionsDlg::OnOkClicked()
{
AfxMessageBox("Ok clicked");
EndDialog(1);
}
BOOL CSelectOptionsDlg::OnInitDialog()
{
CDialog::OnInitDialog();
return TRUE;
}
As I mentioned earlier, if i add this line in OnDraw, its drawing on the first time only,
pDC->TextOut(20, 20, L"test sdi", 10);
Also, in MainFrm.cpp file,
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
ON_WM_CREATE()
ON_COMMAND(ID_START, OnStartPlan )
ON_COMMAND(ID_STOP, OnStopPlan )
ON_COMMAND(ID_SELECTOPTIONS, OnSelectOption )
ON_COMMAND(ID_EXIT, OnExit )
END_MESSAGE_MAP()
void CMainFrame::OnSelectOption()
{
CSelectOptionsDlg cSODlg;
cSODlg.DoModal();
}
doing like this. OnDraw is not calling everytime. What I need is, whenever i click ok and close the dialog, OnDraw need to be called. How can i do that? Any help. Thanks.
Ok, I understood what you are trying to say. I added this line only in the existing function. pDC->TextOut(20, 20, L"test sdi", 10); Also, I would request you to read the "How to answer the question", especially, 3rd point.
Hello Everybody, I am new to MFC. I used the application wizard to create a SDI application, I was able to replace the existing menu and toolbar. In this, I added a dialog with some controls. Now, what I need is, whatever the details I got from the dialog controls, I need to display the document view. On CView::OnDraw,I added the code like this. CSDITestDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); if (!pDoc) return; pDC->TextOut(20, 20, L"test sdi", 10); This text is writing only once in the beginning. On closing the dialog, this function is not called, how can I do that? I tried with UpdateAllViews and OnUpdate also. Thanks in advance. A. Gopinath.
Hello everybody, i am having text file opened in some other application(our application). if i delete this opened file from windows explorer, its deleting, so, at some point, my application crashes (while trying to write). how can i lock that file when it is use in other application? i am using VC++ with win32. Thanks in advance, A. Gopinath.
Hello, Yes, you are right, now its working. thanks. Regards, A. Gopinath.
Hello, sorry, i forgot to add that, i tried this also. CB_FINDSTRINGEXACT also returns the same issue. Thanks, A. Gopinath.
Hello everybody, i am having a combobox (created through resource), and through code, i am updating the combobox with a list. for example, i am filling with "Kir" and "K". if i use CB_SELECTSTRING to select "K", its always selecting "Kir". if i use "Kj" in place of "K", then the selection between "Kir" and "Kj" is fine. from msdn definition : It selects the first list item, if any, that begins with the characters in the specified text. is there any other method to solve this issue? iam trying like this. SendMessage(hList, CB_SELECTSTRING , -1,(LPARAM)(LPCSTR)tt.c_str()); Thanks in Advance, A. Gopinath.
Thanks Albert, hereafter i will use this page to ask questions related. Regards, A. Gopinath.
Hello, i will try using "double" type. actually this is related 3D project, need to find straight line or not. Thanks again, A. Gopinath.
Hello Amarnath, yes, i tried this method also, but iam getting like 0.000002 or something like difference which fails the condition checking. rounding off will solve the solution ? is that right method? Regards, A. Gopinath.
Hello Richard, Yes, i know its a mathematics question, i tried here so that someone can help me. Thanks for the reply. Regards, A. Gopinath.
Hello everybody, i am having n-number of points like p1(x,y), p2(x,y), p3(x,y), .... pn(x,y). All points lie on a single line.(either a curve or a straight line). i would like to find, using those points, whether that line is straight or not straight. i googled and tried some of the methods given in examples, (straight line equation, finding if collinear) but those are not working fine even for straight line also. i am using visual studio 2008 with win32 (not MFC). Any ideas ? Thanks in advance, A. Gopinath.
