I have put them in try catch block for any com error.. by using _com_error i am able to retrive the error code and error message... But i want to filter out some of the error code say 0x80004005 (unexpected error). When this error occurs i just handle the error gracefully without notifying the user of the actual cause. My question is.. Is there any #define for 0x80004005 like #define COM_UNEXPECTED 0x80004005 so that i can use it in my switch case like switch(ce.Error()) { case COM_UNEXPECTED: .... default: ... } now my switch looks like this switch(ce.Error()) { case 0x80004005: .... default: ... } I know that i can #define it myself but i looking for the one that is already defined. Thank You. My God is more powerfull Than Your God.

(the line that divides the world) radio button states coda_x2-Jan-04 16:54 coda_x 2-Jan-04 16:54  i have 2 radio buttons grouped together, variable name is m_button, when i checked the .cpp file, m_button =-1 (initialized). How do i detect which button has been checked? if i use: if(m_button!=-1) then this means can be button a or button b but i want to detect specifically either one. anyone can clarify? thanx Re: radio button states l a u r e n2-Jan-04 18:23 l a u r e n 2-Jan-04 18:23  radio buttons are weird they actually get put into an array in effect so the value u get back is the zero-based index of the radio button within the group (as far as i recall) "there is no spoon" biz stuff   about me Re: radio button states Ravi Bhavnani2-Jan-04 22:28 Ravi Bhavnani 2-Jan-04 22:28  Use separate CButton members for each radio button. Then test this condition: m_checkButton_1.GetCheck() == BST_CHECKED to see if it's checked. /ravi Let's put "civil" back in "civilization" Home | Articles | Freeware | Music ravib@ravib.com Re: radio button states Selvam R2-Jan-04 22:55 Selvam R 2-Jan-04 22:55  Hi, I think radio buttons with in group box ( privious one) is better then separate CButton members for each radio button. Correct!!? With Regards, R.Selvam Re: radio button states Ravi Bhavnani3-Jan-04 6:05 Ravi Bhavnani 3-Jan-04 6:05  I prefer to use individual (CWnd derived) members for each controls. That gives me complete control over my GUI and would also address your issue. /ravi Let's put "civil" back in "civilization" Home | Articles | Freeware | Music ravib@ravib.com Re: radio button states Prakash Nadar3-Jan-04 0:10 Prakash Nadar 3-Jan-04 0:10  There are good tutorials on radio button on CP you can check them out.

I am just wondering, sometimes I see things such as: m_ListBox.ShowWindow(TRUE); and other times I see: m_ListBox.ShowWindow(true); I am just wondering if there is any difference between TRUE and true / FALSE and false or if they both mean the same thing? (ie constants with the same value) Re: The difference between TRUE and true Jörgen Sigvardsson2-Jan-04 15:22 Jörgen Sigvardsson 2-Jan-04 15:22  the difference is that TRUE is a #define and true is a constant, very much like any integer 1, 2, 3, 23423. TRUE happens to evaluate to 1, and the integer representation of true is 1, hence you can use them interchangably. But one should always strive to "put the round ball into the round hole, and not the square hole". -- They say the most horrible things, but I hear violins. When I close my eyes, I'm at the center of the sun. Re: The difference between TRUE and true Michael Dunn2-Jan-04 16:15 Michael Dunn 2-Jan-04 16:15  bool is a C++ built-in type with two possible values, true and false. Nothing else. BOOL is something MS made up for use in Windows and MFC. They needed a boolean type that worked in C and C++, and since they did this before bool was added to C++, they couldn't just reuse bool. BOOL is defined as: typedef int BOOL; #define FALSE 0 #define TRUE 1 The trouble with those definitions is that the BOOL notion of "true" is not 1 but non-zero. A function that returns a BOOL may return 1 to mean "true", or some other nonzero number (I've seen it myself, can't recall the API names off-hand though). Because of that, you should never test a BOOL variable/function against TRUE, just test as a boolean and the language rules will take care of the rest. You should, in general, use bool for your own code, assuming it's C++. You can pass a bool to a function expecting a BOOL because the bool gets promoted automagically by the language rules to the integer 0 or 1, for false or true respectively, which satisfies the definition of BOOL. --Mike-- Ericahist | CP SearchBar v2.0.2 | Homepage | 1ClickPicGrabber New v2.0! | RightClick-Encrypt If my rhyme was a drug, I'd sell it by the gram.
