This is standard C++. You're in the C++/CLI forum, try the visual C++ forum.
If terms is an int, I believe it will keep asking until you enter an int value. Or you can accept a std::string and try to parse it yourself and give custom errors. Things like atoi will help here.

Hi,
How can i access filesystem within c++?
Can i use standard C functions? Like chdir, etc?
Thx,

If you are looking for native code, please ask this in the Visual C++ forum. Else take a look at the classes in the System.IO namespace.

the first text file list item"1c.txt,2c.txt,.........
the second text file list item"1e.txt,2e.txt,........
now the combine file order must be "1c.txt,1e.txt,2c.txt,2e.txt........."

Hi,
I am new to vc++.net (mfc),i need to know how to add data and column headers to the MSDATAGRID VERSION 6.0 dynamically IN vc++.Net(mfc application), Please someone help me.
I have taken an sdi(mfc application) and added a MS DataGtrid, now i need to add column headers and data to the grid.The code i added to write is
m_DataGrid1.put_Row(1);
m_DataGrid1.put_Col(1);
m_DataGrid1.put_Text("Nit");
the error i got is "rowset not available".
Thanks in advance

Hi,
I have used MS HEIRARCHICAl FLEX GRID
//code to add row by row to a grid
m_FlexGrid.put_Cols(0,6); // number of columns(5)
m_FlexGrid.put_ColHeader(0,1); //setting the header
m_FlexGrid.put_ColWidth(1,0,1300); //col width
m_FlexGrid.put_ColWidth(2,0,1000);
m_FlexGrid.put_ColWidth(3,0,1400);
m_FlexGrid.put_ColWidth(4,0,1500);
m_FlexGrid.put_ColWidth(5,0,1200);
m_FlexGrid.put_ColHeaderCaption(0,1,"Employee Name");//adding //captions to the header
m_FlexGrid.put_ColHeaderCaption(0,2,"Employee ID");
m_FlexGrid.put_ColHeaderCaption(0,3,"Employee Salary");
m_FlexGrid.put_ColHeaderCaption(0,4,"Employee Address");
m_FlexGrid.put_ColHeaderCaption(0,5,"Employee Age");
m_pSet->MoveFirst();
int RowCount=0;
while (!m_pSet->IsEOF())
{
RowCount++;
m_pSet->MoveNext();
}
m_FlexGrid.put_Rows(RowCount+1);
m_pSet->MoveFirst();
int Row=1;
int Col=1;
while (!m_pSet->IsEOF())
{
m_FlexGrid.put_Row(Row);
m_FlexGrid.put_Col(Col++);
m_FlexGrid.put_Text(m_pSet->m_EmpName);
m_FlexGrid.put_Col(Col++);
long var=m_pSet->m_EmpID;
CString str;
str.Format("%d", var);//to convert long to string
m_FlexGrid.put_Text((LPCTSTR) str);
m_FlexGrid.put_Col(Col++);
double var1;
var1=m_pSet->m_EmpSalary;
str.Format("%0.2f",var1);
m_FlexGrid.put_Text((LPCTSTR) str);
m_FlexGrid.put_Col(Col++);

Well, if you're using C++/CLI, you can do String ^ = "hello world". Your overall question makes me think that you're pretty lost, and probably taking on a project that's too hard for your skill level. So, you may also be confused about what this forum is for. It's for .NET C++, not C++ in general. The visual C++ forum is for that.

So, you posted your question on a Visual Studio site, on a Managed C++ message board...
Great,

I'm sorry.
Could you recommend a other forum??
Great,

No problem.
I haven't used Borland in many years but I would start here[^].
I'm not sure what kind of script you're looking for but if you look at the list of message boards
at the top of this page you may find a more appropriate board to post the question on.
Good luck!

hi!
can someone give me a sample code on how to pass 2 different structs to a function with lpvoid as parameter and how to convert back to the structs from lpvoid.
the structs should be received by the lpvoid... how to combine the 2 different structs together? and how to split the lpvoid back to the 2 structs?
the structs are something like
typedef struct
{ int dataStructCount;
DWORD totalSize;
} strHeader;
typedef struct
{ int num;
lptstr str;
} dataStruct;
this will be used for writing and reading data from named pipe.. the header will be used to determine the count of dataStruct send/read.
thanks for any help!

Newbie,
First of all, you are in the wrong forum! This is the C++/CLI or Managed C++ forum. C++/CLI uses the .NET Framework and depends on Garbage Collection (GC) for memory management. It appears you are writing C or possibly C++ code. You should get better assistance int the Visual C++/MFC forum.
However, LPVOID is really a typedef of void*. Thus, LPVOID is a pointer to any type. Unfortunately, once a pointer of a type, in your case strHeader and dataStruct, is casted to a void pointer, LPVOID, its type information is lost. Thus, if you have a function that accepts void pointers, the compiler will not help you with type checking.
void Foo(LPVOID header, LPVOID data)
{
strHeader* theHeader = (strHeader*) header;
dataStruct* theData = (dataStruct*) data;
}
int main()
{
strHeader header;
dataStruct data;
Foo(&strHeader, &dataStruct);
return 0;
}

oooopppss! sorry! i did not notice the message board... i thought i was posting in vc++/mfc forum...
i have reposted the qxn there...
thanks for your reply!
however, for the foo function... i only have 1 LPVOID paramter...
thus the strHeader and dataStruct should be combined together and passed as 1 data to function Foo....

Hi
I'd like to be able to take a set of bitmaps and write them to an avi file without having to use vfw or anything platform specific since it has to be cross-platform
i don't need audio or anything else - just a sequence of images - any ideas?
|
|
|

|

hi
thanks for the reply but that article show's how to load an avi file as a resource - what i need to do is save a sequence of images as an avi file without using vfw.

|
|
|

If cross-platform is your goal, then using C++/CLI that depends on the .NET Framework would be a bad idea. You are in the wrong forum.

I'm trying to understand how I can create a DLL that contains a wrapper (managed code), to use a C++ (unmanaged) class using C# or VB.NET.
I found some articles (es http://www.codeproject.com/useritems/WrappingUsingManagedCpp.asp[^])that suggest this way:
(SimpleClass is my C++ class)
namespace Managed{<br />
public __gc class WrappClass<br />
{<br />
private:<br />
SimpleClass* pClass;<br />
public:<br />
WrappClass(){ pClass=new SimpleClass()}<br />
~WrappClass(){ delete pClass; }<br />
int Foo();<br />
};<br />
}<br />
It will be well compiled...but the linker tells that operators 'new' and 'delete' are unknown (error LNK2020)....
What is wrong??? I wrote only 20 code lines!!
Is there some settings in Visual Studio to solve this problem?
Have you got some link to a simple project like mine ... that is working?
Thanks
Cheers,
Russell

Looks like you are using VC++ 2005. If you want to use the old syntax, you need to specify /clr:oldsyntax in the compiler settings.
But I'd recommend that you use the new syntax instead.

mmm...no, I'm using VS2003 (recently updated from internet with some patches).
i tryed to use /clr:oldsyntax....but it doesn't know this option (the option /clr it is just included into che command line).
I also tryed to use gcnew (instead new) but it is an unknown command.
it is driving me crazy
thanks
Cheers,
Russell
