• Delphi overwrite existing file on save dialog

  - by AfterImage

  Hello everyone, I am using the TSaveDialog component to save a file from a button click. However, I am having trouble with saving on an existing file name. Generally, when you want to save over an existing file in Windows, a message box pops up asking you if you really want to overwrite the file. This is not the case with the TSaveDialog component and it will go ahead and write over the file without asking. I was hoping there was a TSaveDialog function or event that I could use but I have not seen anything that looks like it handles this. So it could be that I simplely haven't found the correct method to use. If there is an event, I could use if FileExists(saveDialog.FileName) then //and so forth but the events TSaveDialog has are OnCanClose, OnClose, OnFolderChange, OnIncludeItem, OnSelectionChange, OnShow, OnTypeChange... My question is, how do I pop up a message box to ask the user if they want to overwrite the existing file using the TSaveDialog component. Thanks.

• Sql Distinct Count of resulting table with no conditionals

  - by AfterImage

  Hello everyone, I want to count the number of accounts from the resulting table generated from this code. This way, I know how many people liked blue at one time. Select Distinct PEOPLE.FullName, PEOPLE.FavColor From PEOPLE Where FavColor='Blue' Lets say this is a history accounting of what people said their favorite color when they were asked so there may be multiple records of the same full name if asked again at a much later time; hence the distinct. The code I used may not be reusable in your answer so feel free to use what you think can work. I am sure I found a possible solution to my problem using declare and if statements but I lost that page... so I am left with no solution. However, I think there is a way to do it without using conditionals which is what I am asking and rather have. Thanks. Edit: My question is: From the code above, is there a way to count the number of accounts in the resulting table?
