Body
I found the solution. The reason why the code doesn't seem to be making any effect in my application is because it is making effect only to MyMainDialog. When typing in the Edit Control, the OnChar() being called if from CEdit, so that is the one I have to intercept. You are not allowed to overwrite CEdit::OnChar(). The solution is to create a class that derives from CEdit and then intercept the OnChar() from that class. You you also have to use your class instead of CEdit for manipulating your Edit Control. My code was then reformulated to this: OnChar(): <pre><code>void CustomEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) { if(nChar == '.' && checkPoint == true) //Is a point and there is already a point { //Show message } else if(nChar == '.' && checkPoint == false) //Is a point but there is no point { CEdit::OnChar(nChar, nRepCnt, nFlags); } if((nChar < '0' || nChar > '9') && nChar != 8) //Is not a number or backspace { //Show message } else //Valid { CEdit::OnChar(nChar, nRepCnt, nFlags); } } </code></pre> OnKeyDown(): <pre><code>void CustomEdit::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) { CString temp; this->GetWindowTextA(temp); if(temp.Find('.') == -1) checkPoint = false; //There is no point else checkPoint = true; //There is a point CEdit::OnKeyDown(nChar, nRepCnt, nFlags); } </code></pre> Hope this helps anyone with a similar question. By the way, there are many classes and automated solutions in the internet, I did this manually for learning purposes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
