How to get 'IRowsetFind' interface in oledb sdk !
dear all:
i will use following code in my program(C++) :
discover 'pICommandProperties->SetProperties(1,rgInitPropSet);' return failed code 'DB_S_ERRORSOCCURRED'
so 'pIRowset->QueryInterface(IID_IRowsetFind,(void **)&pIRowsetFind);' return failed!
dear all, please help me! how to get 'IRowsetFind' interface in oledb sdk , and how to use 'IRowsetFind->FindNextRow()'
InitProperties[0].dwPropertyID=DBPROP_IRowsetScroll;
InitProperties[0].dwOptions=DBPROPOPTIONS_REQUIRED;
InitProperties[0].dwStatus=DBPROPSTATUS_OK;
InitProperties[0].colid=DB_NULLID;
InitProperties[0].vValue.vt=VT_BOOL;
InitProperties[0].vValue.lVal=VARIANT_TRUE;

rgInitPropSet[0].rgProperties=InitProperties;
hr=pICommandText->QueryInterface(IID_ICommandProperties,(void **)&pICommandProperties);
hr=pICommandProperties->SetProperties(1,rgInitPropSet);
if (DB_S_ERRORSOCCURRED==pICommandProperties->SetProperties(1,rgInitPropSet))
cout<< "test";
if(FAILED(hr))
{
cout<< "OLEDB Error !\r\nExecute Failed To Set Rowset Properties";
}
hr = pIRowset->QueryInterface(IID_IRowsetFind,(void **)&pIRowsetFind);
if(FAILED(hr))
{
cout << "Failed to get IID_IRowsetFind interface.\n";

Hi guys
I'm having troubles with resources in w98 and one of the questions is the following.
I'm using a resource meter to know the GDI resources available, and when I open a CDialog with a lot of controls (>100), the resources go down and when I close it the resources don't raise again until I close the app.
Is this normal? If not, what can be the cause?
I'm using a lot of CLabel controls (derivesd from CStatic controls classes get it here in codeproject)
Best Regards
Doc

No, it's a memory leak. Some of your controls are creating resources and not cleaning them up. From the sound of it, probably fonts.

Without using MFC how can I tell if the mouse is over my buttons?
I've tried WM_NCHITTEST and WM_MOUSEMOVE along with stuff like ScreenToClient, GetDlgItem, GetDlgCtrlID, ChildWindowFromPoint, ect, but nothing seems to be working.
Any Ideas? Some code would help me out, thanks.

Just do subclassing for CBUtton
e.g
CYourButton : public CButton
{
.
.
};
and AAdd message Handlers
ON_mouse_Move

Can't do that, I'm using pure WIN32 API, no MFC (if I wanted something like MFC I would use VB).

may i know , what are you using. is it SDK , and if so you might have register the class, in WinProc you will receive all the messages

You do not need MFC to subclass button controls. You write your button's window procedure and use SetWindowLong() with the GWL_WNDPROC index to subclass the button.
LRESULT CALLBACK MyButtonWindowProc(HWND hWnd, UINT nMsg, WPARAM wp, LPARAM lp)
{
switch (nMsg)
{
case WM_MOUSEMOVE:
default:
return DefWindowProc(hWnd, nMsg, wp, lp);
}
return 0;
}
SetWindowLong(ButtonHwnd, GWL_WNDPROC, (LONG)MyButtonWindowProc);

GetCursorPos() returns the current position of the mouse. All you need to do is check if it's within the bounds of your button. You can do this in response to a WM_TIMER, but imho it's better to use TrackMouseEvent(). None of this has any dependency on MFC.

Hello,
Does anybody know of a way to automate both opening applications and various application calls (possibly .dll files) in Windows 2000 or XP? For example, I am developing a graphics application in C++. There are various repetetive tasks needed in order to prepare many of the application assets. Also, I wanted to use this program for testing purposes or to automate repetitive tasks for various applications I am using in Windows. Possibly record an action script and then I would be able to play the script at any time to perform the recorded task. This could also be applications that I am developing myself.
Are there any libraries that exist that facilitate this in Windows?
Are there any programs already in existence that are able to perform this task?
Thank You.

It's not a bug, it's an undocumented feature.

Is there a way to tell my VC6 project to execute a script (foo.cmd) before any files are compiled? I tried adding a custom build step (whose dependency is correctly determined), but the step gets invoked after all the source files are compiled.

Add the foo.cmd file to the project and set custom build step only for this file. Custom build steps for specific files are executed before compilation, but custom build step for whole project is executed after compilation and link.

ok, so i got a book on C++, cuz i figure that i need to learn a new lang. VB is ok, but i want to learn new stuff..
anyway, i think this book is for c++6, and i got c++.net2k3
so i am writing the first couple of lessons, basic io stuff, and it doesn't work like its supposed to. lemme show ya:
------------------------------------------
<br />
<br />
#include <iostream> <br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
main (void) <br />
{ <br />
iostream::cout << "What is your age?" << endl; <br />
iostream::cin >> Age >> endl; <br />
iostream::cout << "What is your Character Type?" << endl; <br />
iostream::cin >> CharacterType >> endl; <br />
iostream::cout << "What is your character's description?" << endl; <br />
iostream::cin >> CharacterDescription >> endl; <br />
<br />
iostream::cout << "Your character's age is " << Age << " , character type is " << CharacterType << " , and your character's description is " << CharacterDescription << " <br />
<br />
return 0; <br />
} <br />
-------------------------------------------
so then when i run it, and it asks my age, and i put in 28, it assigns 2 to Age, 8 to CharacterType, and looks like this <its in="" dos="" console="" mode,="" i've="" tried="" both="" win32="" app,="" and="" .net="" app="">:
----------------------------
What is your age? 28
What is your Character Type? What is your Character's Description? Blue
Your character's age is 2 , character type is 8 , and your character's description is b
----------------------------
i did everything just as it is in the book, and when i look at the variables, they say they are supposed to handle more than just one character, but the prog is only taking the one character.
What the...?? <shakes head=""> can some c++.net guru gimme a little help here?
thanks.
Just one a few seconds more, that's all I need. Close a door here, open a new one there, slip a bit of code off to the side to confuse the trail. The logout port is ahead... --«§øùl Ëס§†ëñçê»

This is C. I believe that you get the int return type by default, but it should look like this:
int main()
SoulExistence wrote:
iostream::cout
This is bizarre. You need to #include iostream (is that what you did above), and NOT iostream.h ( I can't tell, you didn't check 'don't treat <'s as HTML tags ). Then cout and cin are in namespace std. There is no namespace iostream. Put using std::cout at the top, and then you can just use cout with no namespace qualification. You also need to put a using for std::cin and std::endl.
SoulExistence wrote:

That only means that if any code in the book does not compile, it is not correct C++. You have the better compiler, but it's unlikely that you'll find any differences for some time.

SoulExistence wrote:
char CharacterType
A char is one character. A string is more than one. And to use strings you need to #include <string>
and put using std::string at the top. The extra include you mentioned was almost certainly stdafx.h, this include MUST be before all the others, but you can ( and I do ) put your standard library #includes and using std::whatever stuff in stdafx.h, so it's visible everywhere.

/* there's some other include that .net puts in there that i don't know what its for, but its a #include "stdafx.h" */
#include <iostream>
#include <string>
using std::cout;
using std::cin;
using std::endl;
using std::string;
// global variables are evil, although they are forgivable at this stage of learning, remember that variables belong in classes.
int Age, Type;
string Description;
/*the variables byte Age, char CharacterType, and string CharacterDescription are set up here */
int main ()
{
cout << "What is your age?" << endl;
cin >> Age; // Putting endl here is ridiculous
cout << "What is your Character Type?" << endl;
cin >> Type;
cout << "What is your character's description?" << endl;
cin >> Description; // Note that cin will stop on a space. You need to use getline if you want to accept spaces in your string, otherwise "Fred Smith" will only get 'Fred'.
cout << "Your character's age is " << Age << " , character type is " << Type << " , and your character's description is " << Description << endl;
return 0;
}

oh, thank you. that is soooo much help.
C++ is a lot diff than VB6, and VB.net is kickin my butt, too. quite the learning curve.

No worries - glad to help. It is a big step to C++ from VB. I'd recommend C# over VB.Net, because that's where Microsoft's focus is going to be in the future.
