Hello, Hopefully somebody will be able to help. In my Delphi 7 application small percentage of users report errors when printing and I'm trying to resolve this with last of them. I'm slightly limited when it comes to testing (as user is physically distant and we are working it out via e-mail), but I get some additional information from ...
I'm finishing an internship at a company and have just been thrown onto this project for the last month where the program is built upon an engine that they "failed" to buy the source code for. Now I've been given the task of finding out why it is failing, on only certain conditions and customer feedback hasn't been great. The main develo...

On the main form there is a DataSource1: TDataSource; and a Table1: TTable; In OnFormShow the table filename is set to: TableFilename := IncludeTrailingPathDelimiter( MyProfileFolder ) + 'Delphi 2009\Projects\Adirondac...
A certain form in our application displays a graphical view of a model. The user can, amongst loads of other stuff, initiate a transformation of the model that can take quite some time. This transformation sometimes proceeds without any user interaction, at other times frequent user input is necessary. While it lasts the UI should be dis...
This is kind of a follow-up question to this. When I'm debugging threads in Delphi (BDS 2006 with update 2) my IDE often hangs, e.g. when the execution runs into a breakpoint that I have set after the app started. Do you have similar experiences? What do you do about it? ...
i want to mark a method as obsolete, but Delphi 5 doesn't have such a feature. For the sake of an example, here is a made-up method with it's deprecated and new preferred form: procedure TStormPeaksQuest.BlowHodirsHorn; overload; //obsolete procedure TStormPeaksQuest.BlowHodirsHorn(UseProtection: Boolean); overload; Note: For this hy...
I know how to get the System memory use using GlobalMemoryStatusEx, but that tells me the what the entire OS is using. I really want my program to report how much memory it alone has allocated and is using. Is there any way within my Delphi 2009 program to call either a Windows function or maybe some FastMM function to find out the me...
Hey, I'm writing an app that supposed to copy a bunch of files from one place to another. When I'm using TFileStream for the copy it is 3-4 times slower than copying the files with the OS. I also tried to copy with a buffer, but that was too slow aswell. I'm working under Win32, anyone got some insights on this matter? ...
I am looking for a list of all file types that can be associated to a Delphi project (all versions of Delphi), more specifically all file types that should be under source control. This site doesn't mention Delphi 2009 so I'm not sure if there may be new file types. Is there maybe such a list directly from Codegear? Putting all the...

Delphi 2007/2009 odd question here: It's possible, based on a component property defined in design-time, to include files in linking or leave them ? Example: If I leave SomeProperty true, when compiling, the unit SomeUnit will be included into my project. Otherwise it will not be included. My second approach to this problem is to depl...
I thought there was something in GExperts to do this, but I can't see it if there is. I have to change the SCALED property (from the default of TRUE to FALSE) in each form in a project that contains about 100 different forms. Because the default value of SCALED is TRUE, it doesn't actually appear as a line in the .DFM file (when viewing...
