Hello,
I will not be able to write the code but these are few lines more in the code
class Variant : public CDBVariant
{
operator () <
operator () >
CString m_strVal;
};
Now I have
vector<Variant>myDataTable;
But if I try to add a member by writing
myDataTable.push_back(v); where v is of type Variant
then I get an error "Unhandled exception,Access violation"
Thanks for replying

First, use your debugger to locate from where the error comes from. Then, if you are still stuck, post some relevant code and use the pre tag to format your code, otherwise we can't read anything (the pre tag is just above the emoticons).

Dear all,
I have some problem while using combobox in my application. The thing is , I want to reload some values to the combo at runtime..
So I choose this way..
myctrlcmb.Clear()
myctrlCmb.ResetContent();
ReloadNewValuesToCombo(&myctrlCmb); // a user defined fun.
------------------------------------------------------------
But after reloading values , the selection in the combobox is not changed. It always shows the selection which was done before reloading the combo..
I used this combo box in a property page where two other edit boxes are also there. So I want also display some values in those edit fields based on the selection in the combo. For that I have used the "UpdateData(false)" function.
my code...(when a selection is made at the combo)--:
OnCbnSelchangeComboAuthname()
{
int iIndex= 0;
int i=0;
CString strAuthName;
ClearAllValues();
iIndex = myctrlcmb.GetCurSel();
myctrlcmb.GetLBText(iIndex,strAuthName);
dlgHandler.setAllFields(strAuthName,m_valauthdesc,m_ctrlrightlist);
m_strNewAuthName = strAuthName;
UpdateData(false); //I assume the problem creator...
}
The combo selection is completely alright when I was not using the "UpdateDate(false)" funtion..But then how can I display my values in those edit fields...
Pls help me to sove this....
Regards,
vinsankar

Instead of associating the Cstring variable with the Edit Box.. associate The Edit box.. and call function SetWindowText from that function to update value in edit box!..

Why is the URL at your signature (the link provided with your name) misleading? There is no such website called www.thatsalok.com!

That is routing to some domain sponsor and there is no such website. See this[^]

You must be landing up at a domain sponsor too. Can you upload a pic?

It has a picture of clouds and flowers and a list of links - Chat rooms, Thats, Homes for Sale,
etc.
Is that the one you see? I just assumed that was his domain

No. I Screen-captured and uploaded what I saw.

No, Sure it isn't. You may land up on domain sponsor advertisements, which sometimes vary depending on your service provider, geographical location, etc.

That is not his home page. That is some domain sponsor and most of the time, such websites would lead to some nasty links. These domain sponsors could just about randomly appear when you mistype URLs, and type URLs which does not actually exist. (I am unsure here)
In addition to that, there is another possibility. See this link[^]

Dear Alok,
Thanks for giving me a valuable suggestion...
I have solved my problem by using the "SetWindowText" functionality of the CEdit ...
ctrlEdit.SetWindowText("khfkhd");
thus I avoid "UpdateData()"....
also Thanks to Mr.NewComer ..for the great article...

What could be the reason that the first paramter of Microsoft defined structures contains the size of that structure?
Suraj Gupta
|
|

There are a few reasons:
1. Ensure you initialize the struct correctly.
2. Signifies the version of the struct.
3. Helps detect incorrectly casted pointers.
4. A means of bound checking for dynamicly sizable structs.
