问题 I'm trying to use a COM DLL (written in Delphi 7) within my Delphi 7 IntraWeb application but it's failing due to DEP. I'm pretty much certain it's DEP that is preventing me from using the DLL because if I compile and run my IntraWeb app as a StandAlone Server, everything works fine. But, compiling and runnning it as an ISAPI DLL, it fails. On WinXP (using IIS 6) I can add DllHost.exe to DEP and everything works. Of course, I really don't want to do that. On Win7/2008 (IIS 7) this isn't an

问题 I'm trying to figure out how to read the full URI from a request ( Web.HTTPApp.TWebRequest ). There is a URL property, however it returns empty, and I don't see any more properties which could give me this. How can I get the complete URI of the request?

Within the context of a thread running under a parent process, I'm able to work with String variables, but I'm having difficulty trying to figure out how to convert an Integer to a String in Delphi.

问题 I have a RTF file that I am loading into a TRichEdit control. Only problem that I am facing is, RTF file has Tables in it, loading the same shows table borders. But when I load the same RTF in MS Word it doesn't show any borders(Client want the same behavior). Is there any way for not displaying borders of table while loading into TRichEdit.

问题 I am trying to add an array of TBitmap images to different records of a ClientDataSet (in a ftBlob field) and then save those records to a SQLite database. The BLOB field (DocImage) is a required field in the database. However, my code does not seem to save the bitmaps to the blob field in the ClientDataSet at all... So when I call BdmMain.cdsTrxDoc.ApplyUpdates(0) , I get the error: "Field 'DocImage' must have a value." I have checked the size of my BlobStream (BlobStream.Size) before and

问题 I have a Delphi bitmap (32Bit) that has transparency information. I need to convert and save it to a PNG file while preserving the transparency. The tools I currently have are the graphics32 Library, GR32_PNG (by Christian Budde), and PNGImage (by Gustavo daud). What is the best way to do this?
