{
va_list va; // [sp+18h] [bp+10h]@1
int result; // eax@1
size_t v5; // esi@1
char *v6; // edi@1

I think your best bet is to look up Matt Pietreck's various books and articles. He does that soort of thing on a regular basis.

How to change the exe file's icon shown in the explorer?

Re: How to change the exe file's icon shown in the explorer?

11-Aug-08 20:37

I know using the CWnd::SetIcon to set the icon for the program executing,
but how to make the exe file use the icon too in the explorer?
It always uses the default ugly MFC icon!

because you probably modified it, but didn't change every devices of the icon, did you ?

also, a possible error if you didn't modify the default icon but added yours to the project, is because the MFC default icon ID is smaller than your icon in the resource.h file...

check that out

Windows explorer will choose the first icon in the exe's icon list. So ensure that you icon have the smallest icon id.

1) Now insert your favorite icon to project,
2) edit the resource.h and assign the id of your icon as 128(id of default MFC icon).
3) If any other Icon id have 128 as id, update them accordingly to avoid conflict. For instance,

#define IDR_MAINFRAME                   129
#define IDI_EXE_ICON                    128

Thanks for your reply.
But sorry for not working.
I change my fav icon id to 128. But not working.
These things always make me mad!(The things work fine with others, while not fine with me!)
Any reason?

Jijo.Raj11-Aug-08 23:30

Re: How to change the exe file's icon shown in the explorer?

11-Aug-08 23:30

1) I hope you've clean and rebuild it.
2) I hope there is no other icon id which have id 128.
3) if 1 & 2 is ok, then could you post the relevant section in resource.h?

Regards,
Jijo.

Sorry for not cleaning the project.
Just rebuild the project!
Thanks, all guys!^_^

Re: How to change the exe file's icon shown in the explorer?

11-Aug-08 23:33

I hope you didn't just took 128 from the example but understood what you were doing, right ?

128 was just an example. You had to track back in resource.h first the ID of your own icon.

so, to start back from the beginning, how did you add your icon in your program ?

Re: How to change the exe file's icon shown in the explorer?

I create a dialog based project.
then do my jobs.
I notify I need a more beautiful icon for my dialog, then I import a new icon.
And use CWnd::SetIcon to set the icon for the dialog.

And then I modify resource.h exchange myiconID and IDR_MAINFRAME's ID number.

Don't say 128 is the default smallest icon id?

By making sure that all icons in your project's .ico file are correct. You likely just changed one of them and left the other one (or two) as default.

push_back error

Hi all,

I am having this push_back error, this is my struct:

struct RMUpdates {		
		RMUpdates(): prdName(L""), nameVer(L""), link(L""), savePath(L"") {};		
		wstring prdName;
		wstring nameVer;
		wstring link; 	
		wstring savePath;
	};

	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;
		wstring m_SiteCode;

		//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;				
		}
	};

Now when i perform this:

RMproduct* prd

RMUpdates* update = new RMUpdates;
update->prdName = prd->m_Name.c_str();
update->nameVer = prd->m_Name.c_str();
update->nameVer.append(L" ");
update->nameVer.append(std::wstring(A2W(pDoGetLatestProductResponse->DoGetLatestProductResult->Version->c_str())));
update->link = DOWNLOADLINK;
update->savePath = SetDestination(update->link.c_str()); 					
prd->updateList->push_back(update);

Then I will get an error here:

size_type size() const
    {   // return length of sequence
    return (_Myfirst == 0 ? 0 : _Mylast - _Myfirst);
    }

Any advise?

thanks,
Jayjay

The member RMproduct::updateList is a vector pointer and you are not allocating it nor initializing it anywhere in your constructors.

Allocate updateList in both constructors - RMproduct() and RMproduct(wstring szName, wstring serv, wstring version) will solve the problem.

Jijo.

What do you mean exactly?

here are the values passed:

update->prdName = prd->m_Name.c_str() Point

Point 4.3.1.54

update->nameVer = prd->m_Name.c_str();
update->nameVer.append(L" ");
update->nameVer.append(std::wstring(A2W(pDoGetLatestProductResponse->DoGetLatestProductResult->Version->c_str())));


update->link http://downloads.magnetron.com/Point/Point.zip
					

update->savePath
C:\DOCUME~1\JONATH~1\LOCALS~1\Temp\ManagePoint431InstallerBuild_54.zip

Unhandled exception at 0x00496f56 in UpdateService.exe: 0xC0000005: Access violation reading location 0xcdcdcdd5.

Can you explain further what i need to do?

Thanks,
jayjay

Do you mean something like this:

prd->updateList =  new vector<RMUpdates*>;

Jijo.Raj11-Aug-08 21:08

11-Aug-08 21:08

Yes! It should be done in the constructor. Since your destructor is deleting it.

Jijo.
