String and wstring question

27-Jul-08 21:53

With every new release of MFC, there are additional security features, additional classes, more methods added to existing classes, etc., I don't know if you will be able to find a document which would do a side by side comparison between two versions of MFC.

If you need to know the new features of a specific version of MFC, just Google for "What's new MFC X.0", X being the version of your interest (or even better, try looking into MSDN?!).

Besides that, these links may be of your interest:

Hi all,

I have this class generated by gsoap:

class SOAP_CMAC _ns1__DoCheckForProductUpdates
{
public:
	std::string *productName;	/* optional element of type xsd:string */
	std::string *productVersion;	/* optional element of type xsd:string */
	std::string *serialNumber;	/* optional element of type xsd:string */
	std::string *siteCode;	/* optional element of type xsd:string */
	struct soap *soap;	/* transient */

then my structure:

struct RMproduct
	{
		RMproduct(){};
		RMproduct(wstring szName, wstring serv, wstring version){m_Name = szName; m_serviceKey = serv; m_versionKey = version;};

		wstring m_serviceKey;
		wstring m_versionKey;

		wstring m_Name;
		wstring m_SerialNo;
		wstring m_VersionNo;
		
		//xml	
		vector<RMUpdates*>* updateList; 
		~RMproduct()
		{
			if (updateList !=NULL) {
				vector<RMUpdates*>::iterator Iter;	
				Iter = updateList->begin();
				for (; Iter < updateList->end(); Iter++)				
					delete *Iter;
				updateList->clear();
			}
			delete updateList;				
		}
	};

I cant find a way to pass the value of
wstring m_Name;
wstring m_SerialNo;
wstring m_VersionNo;

to

std::string *productName;
std::string *productVersion;
std::string *serialNumber;

thats what I need to be able to use the methods of the webservice.

Thanks,
jayjay

You actually need a string conversion. You may use, for instance WideCharToMultiByte [^].

What is the use of that string pointer (string* serialnumber)?

CPallini27-Jul-08 21:25

27-Jul-08 21:25

Well, the library documentation should state if you need to allocate the string object or you just nned to use it.

How can I get the Index of a tree control Item ?

Use W2A() macro for painless conversion. Wink | ;)

For instance,

#include "atlconv.h"

// The wide string.
wstring WideString = L"Hello";

{
   USES_CONVERSION;

   // converted string.
   string str = W2A( WideString.c_str());
}

Jijo.

I have a tree tree control with check boxes corresponding to the
leaf items. How can I retrieve the zero-based index of the leaf item
when I click on their corresponding check box.

Thanks in advance

You may compute it traversing the childs of the selected item's parent.

I could write the following code snippet based on the suggestion to accomplish the requirement :

HTREEITEM	hSelectedItem = m_pwndPageTree->HitTest(&HitTestInfo);
:
:
HTREEITEM hNextItem = m_pwndPageTree->GetRootItem();

INT	nCounterForPageIndex = 0;

if (hSelectedItem != hNextItem)
{				
while (hSelectedItem != hNextItem)
{
	hNextItem = m_pwndPageTree->GetNextItem(hNextItem, TVGN_NEXTVISIBLE);
	nCounterForPageIndex++;
}					
}

Thanks for the suggestion

how can i select all rows in report?
ex:

m_list my CListCtrl.

for(int i=0; i<m_list.getitemcount();i++)>
{
if(m_list.GetCheck(i))
{

CString s1 = m_list.GetItemText(i++,4);

m_rezult.SetWindowText(s1);

}
}

this not work ...
i whant to do somenting like this :

col1|col2|col3|
--------------
1 | 1 | 1 |
--------------
2 | 2 | 2 |
--------------
3 | 3 | 3 |
--------------

lets say i have checked row 2 and 3 and i have this :
row 2 (col3) + row3(col3) = m_result.SetWindowText(...);
How can i do that?

Please
1. use code block button to surround code snippets with <pre> tags.
2. explain more clearly what do you need to do.

you would need to handle the mouse click event on the list control and get the selected items. On every selection made, you can take the selected items from the list control and put the result in the next row that is empty.
I hope that I got your question correctly.
Use CListCtrl::SetItemData instead of SetWindowText or see InsertItem

no ,i want to display the result from row 2(col2) + row2(col3)in m_result - CEdit

and i have another problem :
i want to display the result from col 2 for ex:

col1|col2|col3|
---------------
1 | 2 | 3 |
---------------
1 | 2 | 3 |
---------------
1 | 2 | 3 |
--------------

col2 have (2,2,2) i want to sum this and put the answer in CEdit(m_result) (2+2+2 = 6)
6 i need in CEdit

See CListCtrl::GetItemText. You can use this function to get values of sub items and then perform operations on the value and display it elsewhere

Hi,
I downloaded CComboCompletion code and used in my application.My problem is:

I have to use this class for two seperate dialogs using combobox.
For first dailog,i used this and its perfectly working.After tht i used this in another dialog in same application, when i changed memebervarialbe type as CCOmboCompletion from CComboBox,when i run it..its shows unhandled exception.

Whther i can use this CComboCompletion class to only one dialog..IF i want to use for amother dialog wat can i use?
Because this CComboCompletion is very useful for my application.
Pls help me??

Anu

_AnsHUMAN_ 27-Jul-08 19:05

Re: CComboCompletion problem

27-Jul-08 19:05

Did you try and debug the code?
Just check the properties of the combo box in the sample and compare them to what you have set. May be there would be some uninitialized variable.
BTW did you try to understand the logic before implementing and using the class?
