No problem when using VC6.
With vs2008, it compiles but not take effect.
Extended style for CListCtrl:
LVS_EX_HIDELABELS|LVS_EX_SINGLEROW
I've tried to define WINVER and _WIN32_WINNT higher as
#define WINVER 0x0600
#define _WIN32_WINNT 0x0600
but also no effect.

I don't know if it is a good idea. Anyway you probably have to go deep inside system internals. Maybe asking the Hardware / Device Drivers [^] will help.

Probably because your idea is too ambitious. What about a simpler project?

Hence you can do just console applications.

hi,
I used mapobjects2.3 (ESRI product) to develop, In Application class
a error occur:
if (!ProcessShellCommand(cmdInfo)) // error occur when run at this line
return FALSE;
The tip as follow:
Debug Assertion Failed!
Program:E:\WMDQS\bin\WMDQS.exe
File:occsite.cpp
Line:161
For information on how your program can cause an assertion faile,see the Visual C++ documentation on assertion.
(Press Retry to debug the application)
Terminate Retry Ignore
press the "Terminate" button, display the next tip as follow:
Unhandle exception in WMDQS.exe(DAO350.dll):0xC0000005:Access Violation.
In fact in my paogram I use ADO to link my database not DAO. So I think that maybe mapobjects2.3 used dao350.dll. I had used regsvr32.exe
to regesit dao350.dll and Mo20.ocx, but it is no use. I had used GOOGLE
to search ,but I had not found the satisfactory resoult . How to solve this question?
My compile environment is :
Visual C++ 6.0 + sp 6, Windows XP sp2 (Simplified Chinese Version)

Maybe try that option and debug You should be able to see the cause of the assertion.

Hi,
I want to login (a htmlpage in ie control)
But ,I don't know the id or name of the button
How to click the login button?
I found some code,but you must know the name or id of login button?
void SubmitPage(IHTMLElementCollection *pobjAllElement,CString strName)
{
CComPtrp Disp;
pobjAllElement->item(COleVariant(strName),COleVariant((long)0),&pDisp);
CComQIPtr pElement;
if(pDisp==NULL)
{
AfxMessageBox(strName + "????!");
}
else
{
pElement=pDisp;
pElement->click();
}
}
Thank you!

for your question how to submit, try this; get the form element and submit form, IHTMLFormElement::Submit().
But what is your scenario how you are entering the login info without knowing the id?
|
|
|
|
|
I dont know the login button's name or ID
|
|
|
|
|
if the login button is of type submit, you can explicitly submit the form without knowing the button id using IHTMLFormElement::Submit() (refer for more handling) .
chinakknd wrote: I dont know the login button's name or ID
 this you already mentioned in your origial post, I am asking how you enter login info (login name login password) without knowing the ids. In order to automate such things I think you need to know the information of the elements.

Here's a ridiculously simple question. What's the equivalent of SetCursor for MFC MDI child windows? I have looked through the documentation but can't find it. (I found the WaitCursor functions, but that's not what I want.)
How do I set and reset the cursor for an MFC MDI application?
Thanks.

I need to have a C++ MFC project use an icon that has 8 bit alpha transparency ... not just 1 color transparency.
The furthest I've gotten is converting
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME)
to
m_hIcon = (HICON)LoadImage(::AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_MAINFRAME), IMAGE_ICON, 0, 0, LR_CREATEDIBSECTION);
and trying some variations on the last parameter such as LR_LOADTRANSPARENT.
Please help. Thanks!
|
|
|
|

Is your icon already authored to be 32-bit?
If so, a simple load like this should work (don't use LR_SHARED if you want to destroy the icon yourself)...
m_hIcon = (HICON)LoadImage(::AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_MAINFRAME), IMAGE_ICON, 0, 0, LR_SHARED);

Hi everyone,
I'm trying to use some registry functions from the Windows API in a native C++ project.
The thing is that I'm getting an error that says RegGetValueA cannot be found in ADVAPI32.dll, but I'm not using that function. Instead I'm using RegQueryValueEx.
Anybody knows why this happens?
Thanks

Nevermind. I found the problem.
I used the problematic function before and it seems it remained somewhere in the compiled code.
A rebuild solved it.
Thanks anyway

I have the follwing code:
class MyStruct {
public:
std::string s;
};
class Test {
public:
operator std::string() const {
return std::string();
}
operator void* () const {
return NULL;
}
operator char () const {
return 'a';
}
};
It's nonsensical but bear with we. The idea is that the Test class should convert to various types, so the expression:
Test t;
std::string s = t;
compiles fine, where "s" is assigned whatever the result of Test::operator std::string().
Why then do I get compiler errors ( both on VC6 and VC8) when I do
Test t;
MyStruct m;
m.s = t;
It complains about "error C2593: 'operator =' is ambiguous"? What am I missing??!
If I remove the operator char() converter then it compiles fine. But why does this work in the first case and not the second?

It's not C++, is it string class (operator overloading) interaction with your ones.

Nothing.

Because of the string::= operator, that accepts a string as well a character, hence the ambiguity.

OK, but why does the second example fail? It's also assigning it to a string class?
The only difference is that it's now a member variable.
m.s = t;
where "m" is a MyStruct type and m.s references the member variable MyStruct::s which is a std::string. So how is that any different than doing
std::string b = t;
The first one fails, the second one doesn't, yet both reference a std::string variable!

Because in the
std::string b = t;
example the compiler, under the hood, is calling the string contructor instead of the assignment operator. You can test the following little change:
std::string b;
b = t;
BTW to be honest, I missed your first example, before .

first takes "copy constructor" while the second takes "assignment operator". string doesnot have copy constructor that takes char.
to avoid ambiguity in "assignment operator" specify explicit typecast.
m.s = std::string(t);

Hello experts,
I have the need to create a small, non-GUI application, which would consume no more than 300k~320k of memory...
My code should also have the ability to use Win32 API.
When I tried a "Win32 Application" project, even with no more than an empty WinMain() function, it consumes about 1000k of RAM...
BTW, I use windows Task Manager to read memory consumption...
What kind of project should I create?
Any guidelines?
I know C++ as a language, but have never actually written anything with it...
Thanks in advance,
Shy.

Why?.
(i.e. do you really need such a strict contraint?)
