Where can I find a good resource for adding print capabilities to my program? I found this page: http://efg2.com/Lab/Library/Delphi/Printing/index.html but it hasn't been updated in 5 years, and I'd like to know if, with Delphi 2009, StretchDIBits is still preferred to StretchDrawMap, how to best support pagination, preview, etc. To da...

In Delphi, you can use compiler directives to disable specific warnings, such as {$WARN USE_BEFORE_DEF OFF} But when I tried to do that with a specific hint, whose underscore_style_name I got out of the helpfile, the compiler said it doesn't know what {$HINT} is. So is there any way to do this? ...

Hi! Yes I want to read a simple a logfile into a TStringList and that is easy done with LoadFromFile. But the problem is that the file can be already opened by another program at the same time so an exception may appear. I have tried to use: FileMode := fmShareCompat; But it won't work. I have also tried to use: fFilePath := fPathL...
Hi, I'm using ADO-components to connect to an access database. In a column defined as text with width 50, dataaware textfields always displays 50 characters even when the actual string value contains less characters. The value gets padded with spaces, and if the textfield is not wide enough, it looks like it is empty. Anyone got any cl...
Referring to TLB and maintenance issues ... My question to people (often) using the new COM/ActiveX type library support in Delphi 2009: How stable is the implementation? Especially, I'm interested in: adding/deleting classes, changing GUIDs, renaming methods/properties, reordering methods/properties, huge type libraries (50+ classes),...

One of the problems I often run into, is that I will include 'Windows' in my uses clause, and then I will later add 'JwaWinBase' for some specific calls. However, many of the functions in the 'Windows' unit are the same as in JwaWinBase, and I start getting errors in my main unit, all over the place, until I fix all my calls by pre-pen...
I have an application written in Delphi that has several versions that contain binaries and database (MDB) with catalog data. During the product life cycle fixes/enhancements are either in database file or in some binary files. Version are preserved in Registry. Users might have different versions of the program when new patch is ava...
Hey all, Please down vote me if this is not appropriate, but I'm desperate to the point of pulling my hair out looking for this link. This is really a last resort. Recently I browsed to a blog (at least I think it was) that had a very detailed description on how to modify a TListBox to have a multi-line look resembling some of the entr...
In this question is mentioned the wcrypt2. What I need is simply calculate the MD5 of a file. It would be perfect if I could calculate it without having to save it because it is a downloaded file in stream format. I would like to have the most straightforward way to do that. Thanks! ...
I often accidently step into code that I'm not interested in while debugging in Delphi. Let's start by saying that I know that you can step over with F8, and that you can run to a certain line with f4. Example: function TMyClass.DoStuff():Integer; begin // do some stuff bla(); end; procedure TMyClass.Foo() begin if DoStuff()=0 ...
I know there's an API for creating extensions to Delphi. I use the GExperts package and various JVCL experts frequently. But I've never seen any extensions to the debugger. It would be very nice, for example, to be able to register viewers for various objects instead of having to examine them in the Inspector. (A form with an image c...
