Hi, I occasionally get SOAP time outs and I am sure it is the connect time out that is causing the problem. After 30 seconds, I always get a time out. By googling, I found suggestions to InternetSetOption that can be used to set the time outs, however on my machine, I have SOAPHttpTrans.pas (CodeGear Delphi 7) which has the following c...

The messagefilter works like a charm when I automate Word directly like: Word.Documents.Open(...) Document.SaveAs(...) But when I call TOleContainer.DoVer...
When I approach Java problems, I use the collection pattern. However, doing it in Delphi is quite a nightmare since there is no Integer object to handle things. I need a data structure that holds numbers. I want to be able to add numbers, remove numbers, and check the contents of the collection, and each number must be unique. I'm not...
I put several 3rd party controls in a DPK file in order to install them all with a single click when I (re)install Delphi. One of the controls in this DPK is Melander's GIFImage.pas. The thing is that the blue dots do not appear in this file when I compile the package. Why? The file IS compiled. I have deleted the DCU and I put some ga...

Hello! I use Delphi 2007 and have a pretty intensive program that I've been working on for a few years. Besides honing the logic, I've used RtlVclOptimize and the full version of FastMM4 (so I can set some of the IFDEFs to my liking). My questions are: "Is FastMove usable in Delphi 2007?" (My analysis says it seems to be.) "Is FastM...
This must be a Delphi bug... I have a unit which is the basis of my persistance framework. In that unit I have a base class for all my domain objects, a list class and a generic list class. Just recently I noticed that when I step into the unit when debugging, execution will jump to a point a little further down in the file than it sho...
