We have a GUI of several frames that build their contents dynamically. Each frame creates panels, labels, edits, comboboxes etc to be used as input fields. This is working very well and we are also planning to let each frame build its content in separate threads. However there is one big problem: it is rather slow! Creating the control...

hi all! I'm going to advise a company on a project soon, and I'm not too sure about what programming language I should advise. It's a fairly straightforward (desktop based) application with a central datasource on the network, for storing and editing parts that make up a machine. The machine needs to be configured in the application, a...
I'm having a bit of trouble with an old delphi.net application. I need to show some thumbnail images on a specific location on the page, and when the user clicks the image show the image. The images are rather small so I havn't bothered with thumbnail generation. The problem is that I can't get the onclick event working. Here is m...

I have a TFrame descendent that has on it a sizable panel which is a third-party component (TLMDSimplePanel)). The sizing on that panel works great, but I want the frame it is contained in to resize dynamically when the user changes the size of the panel. (The panel has a little sizing thumb grip on it that the user can just click and ...
I have four small single-form utility applications that I have written in Delphi (Win32), that every once in awhile I want to use in a way that makes them "feel" as if they are all one application, mostly to make switching back and forth between them super-easy. It would be great, for instance, to be able to insert them as containers ...

Hello I am using turbopower's stExport from the systools' package. Using it to export a dataset. That works great. The Class makes available FOnExportProgress.

We develop a database application. The user asks for a new feature, to copy blobs into the clipboard such that Windows Explorer can paste them as new files. One solution is to save the blobs into a temp folder and add these temp files to the clipboard. But I'm looking for a better solution. Is it possible to hook the paste action in Wi...
As far as I know, strings are immutable in Delphi. I kind of understand that means if you do: string1 := 'Hello'; string1 := string1 + " World"; first string is destroyed and you get a reference to a new string "Hello World". But what happens if you have the same string in different places around your code? I have a string hash assi...

In your experience, is one version of Delphi significantly faster and more stable then the rest of the versions. Provide specific examples when possible. ...
Whenever you add a new unit to the project Delphi rebuilds the .dpr file and all the IFDEFs in the uses section are gone. To work around this I typically use NotePad to create new .pas files, and add it to the .dpr manually. If I need a form I use File->New->Form and then revert the .dpr file to the previous version. Not very RAD if you...
Delphi 2007. I have a TGrid with more rows than will fit on the screen, and the height of the grid is such that there is a partially drawn row at the bottom. When I click on this partial row, it jumps up to be fully visible (via a procedure called 'ClampInView' in Grids.pas). But it doesn't stop. Since the mouse is now over a new partia...
What about a feature in an upcoming Delphi version enabling that? Maybe it could be a compiler switch promoting all privates to strict privates. ... or it could be a feature of the new non-legacy compiler font-end Nick Hodges was talking about. => private does always behave like strict private. EDIT: The reason why I want this is bec...
