Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
Read the question carefully
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.
I'm doing a program that computes the sum and product of the integers from 1 to 5. Weird thing is when I run the program I get the correct answer for the sum. The sum says 15. Correct. But I get the wrong answer for product. I get 6.
I cannot figure out where I'm going wrong:
// This program computes the sum and product of the integers from 1 to 5
i : integer;
sum : integer;
product : integer;
sum := 0;
product := 1;
for i := 1 to 5 do
sum := sum + i;
product := product * i;
WriteLn('The sum is ' + IntToStr(sum));
WriteLn('The product is ' + IntToStr(product));
WriteLn('Press Enter to quit...');

I'm making a VCL project with Delphi Tokyo, but I've been problems, because when I've been compiling and executing my appllication, it generates some exceptions with class $c000005. However, I put some breakpoints in the code but it doesn´t function.
when it starts automatically marks the exceptions, and Delphi not specify the line that generate the exception.
"Exception code: C0000005 ACCESS_VIOLATION" means that your code is trying to access a part of memory outside of its process limits. This is usually caused by bad pointer or array indices. Check your code to see where there may be any such possibilities.
I am trying to get two columns in TGridPanel, where user will be able to drag , drop and move around GUI components(TImage) at runtime.
I can drag and drop, however TGridPanel doesn't show scrollbars when I drop a lot of elements. It starts to shrink the ones already init. To have scrollbars I added this grid panel on TScrollBar and changed "Align" property to "alClient".
My plan is to save the final setting of components in a 2D array. My plan is to have at least one component per row to save the row of TGridPanel.
I have a Main Form which opens up an Archive Form. I'm sending data over from another computer to which shows up on the Main Form right away if the Main Form is open, but if the Archive Form is open I have to close the Form and reopen it for the data to show up. What I was wondering is their away I can get the data to show up on the Archive Form without closing and reopening the Form. Can I do a Refresh, Invalidate or anything like that?
