One solution is to loop through the source string and assign new lines accordlying.

Popup MsgBox without a parent to pass?

i have a function which vb is calling from my c++ dll.. the function takes a little while so i wanted to popup a dialog telling them to wait a bit.. im assuming that i cant popup a dialog from a dll as i am crashing when i tell the dialog to go modal:

INT_PTR CDialog::DoModal()
{
	// can be constructed with a resource template or InitModalIndirect
	ASSERT(m_lpszTemplateName != NULL || m_hDialogTemplate != NULL ||
		m_lpDialogTemplate != NULL);

	// load resource as necessary
	LPCDLGTEMPLATE lpDialogTemplate = m_lpDialogTemplate;
	HGLOBAL hDialogTemplate = m_hDialogTemplate;
	HINSTANCE hInst = AfxGetResourceHandle(); <--- crashing here

is there a built in messagebox that doesnt have an ok or cancel that i can show and hide without needing a resource? i have a progresswnd that i got here from CP, but it crashes because i pass NULL for the parent.. is there a way to tell the parent that is calling the dll's function? or a way to pass a CWND pointer from VB into my function?

thanks for ne tips!

still a newb.. cut me some slack :P

woops looks like i was crashin with the progress window because i left out the following in the begining of my dll's function:

AFX_MANAGE_STATE(AfxGetStaticModuleState());

woops! but for reference, is there a window built into mfc i can show and hide with no ok or cancel on it?

thanks!

Nope. That would have made MFC more than just a wrapper class library, and (apparently) the MFC developers didn't want to work too hard. Smile | :)

please reformat the code. Use the < > buttons below for the <> signs because they get eaten by the codeproject beast.

After it's reformated, can you tell us what is the problem ? does it crash, does it give bad results ?

Are you sure you don't go over the array bounds in the loop ?

Thanks.

Driver not capable at Update

I am starting to receive driver not capable error about a week ago on one of the Oracle tables I used in the application, when doing an Update to the CRecordset.
For example:
m_pSet->Edit();
UpdateData(TRUE);
m_pSet->Update();

I have VC++ 6 Enterprise and Oracle ODBC 9.x. This problem only occurs in one table.

Hmmmm, it sure smells as though you don't have UPDATE privileges on the table.

I am not sure what was causing it. For sure it is not the update privilege. After I reset the filter (m_pSet->m_strFilter = ""; m_pSet->Requery(); and did some m_pSet->MoveNext() to get to the record), I was able to do an update successfully.

Driver not capable does not tell me any information about why sometimes I can't do an Update().

After an EDIT(0 ,there should not be any call to Move XXX() functions .Did u try the function canupdate() function

Re: Driver not capable at Update

ElizabethC12-Mar-03 12:29

12-Mar-03 12:29

There was not a Move function after Edit function. However, I didn't check if the record set CanUpdate. Does CanUpdate give me a more specific reason instead of Driver not capable?

I am trying to access an html file which is in the same directory as the .exe of the program, but whenever i nav there it adds http:// to the url. I do not want to use the full file://c:/... extension but would like to do it local to the exe.
If anyone knows an easy solution could you fill me in?
I am not sure wehre they will put the exe and all that when it is on the client machine so i would like to access it in a relative url fashion, however if someone knows some code to find the current path of the program that i could use that and attache like index.htm on it.

Any help or sample code would be appreciated

Hi
I've just worked a bit with the CListCtrl but i want to have gridlines around items and subitems.

I think it's very simple, but i don't seem to find it

A little sample:

//------------------------------------------------
// Obtain the current style and style ex...
DWORD dwExStyle = this->m_cLCtrlParametritzacions.GetExtendedStyle();
DWORD dwStyle = this->m_cLCtrlParametritzacions.GetStyle();
//------------------------------------------------
// Modify the styles as desired
dwStyle |= LVS_SINGLESEL | LVS_SHOWSELALWAYS | LVS_NOSORTHEADER;
dwExStyle |= LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;   <code>this is what you want</code>
//------------------------------------------------
// Apply those styles...
this->m_cLCtrlParametritzacions.ModifyStyle(0,dwStyle);
this->m_cLCtrlParametritzacions.SetExtendedStyle(dwExStyle);  <code>Here is where the modification gets applied</code>
//------------------------------------------------
// Hack the items height using a imagelist whitout icons...
this->m_cilHackItemHeight.Create(1,30,ILC_COLOR,1,1);
this->m_cLCtrlParametritzacions.SetImageList(&m_cilHackItemHeight,LVSIL_SMALL);

Hope this helps...

m_listkiezers is a CListCtrl.

at: DWORD dwExStyle = m_listkiezers.GetExtendedStyle();

i get the following error:
error C2039: 'SetExtendedStyle' : is not a member of 'CListCtrl'

I searched for the class members for CListCtrl and 'SetExtendedStyle' was in it but it won't accept it.

Can you help me?

Thanks

hi Joan

void CDlgM4_1::SetGridLines()
{
m_listkiezers.ModifyStyleEx(0, WS_EX_CLIENTEDGE, 0); //WS_EX_CLIENTEDGE: specifies that a window has a border with a sunken edge.
m_listkiezers.SetExtendedStyle(LVS_REPORT|LVS_EX_GRIDLINES);
}

and error here:
error C2039: 'SetExtendedStyle' : is not a member of 'CListCtrl'

I use Microsoft Developer Studio 97, Microsoft Visual C++ 5.0 (Corporate Edition)

How this helps. Confused | :confused:

get the last # from a 2 digit sum

Hey,
Is there a way that you can take the last number (one's digit) from a sum of 2 numbers added together? For example if I have numbers like 4, 8 that = 12. I only want to take the 2 though. Is this possible?
Thanks
Matt
