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.

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?
As stated in the subject, I'm using XE8 with Castalia. Whenever I'm writing code, I get the message "Castalia exceeded its allowed memory threshold for parse trees" repeatedly in the Messages log. Does anyone know what causes this, or how to go about fixing it?

I have the sample project, but there is no option available to include attachment. so i explain my project here.
I created server application with two units
On TDSServerModule1 i dropped TSQLConnection and added parameters to connect to SQL Server database "master" (using MSSQL driver)
On mainform I dropped TDSServer, TDSTCPServerTransport, TDSServerClass and connected them with TDSServer.
I added the following code in the OnGetClass event of the TDSServerClass
PersistentClass := TDSServerModule1;
Next I created client application with Only one form
i dropped TSQLConnection connected to server application (using DataSnap driver)
i right clicked and generated 'Client Classes' using 'Generate Datasnap Client Classes' menu
i dropped TDSProviderConnection component and connected to TSQLConnection
i dropped TSqlQuery component and connected to TSQLConnection. I write the following query
Select * from sysdatabases
I want to select all rows from table "sysdatabases" which is exist in master database.
When i execute the Open command, it is throwing the following error
"Remote error: Dbx.SQL is an unrecognized command type."
My objective is to create multi tier data snap application. But i want to add TSqlQuery in the client application and to execute select, insert, update, and delete commands directly from the client application.
Usually we put tsqlconnection (dbconnection) and tsqlquery on the server side, and clientdataset on the client side.
But I want to use database connection on the server side, but TSqlQuery on the client side of the datasnap multi tier application.
The reason behind is i created one sample application using TMS workflow studio component, when I use that component in the multi tier datasnap application it throws the same error. It seems that they are executing the query on the client side.
So I want to make sure the possibility to use TSQLQuery in the client application of the multi tier datasnap application
Is there any way to send my sample project to you thru email. my email id is email@example.com

I just can't seem to get this right.
I have a Com Class written in VB.Net that brings up a form where users can enter information.
I have a delphi program that opens this class and it shows the form fine.
The problem I have is with events raised in the Com Class. It just does not get fired in delphi, although I can assign it to a procedure.
