I am developing an application that uses Crystal Reports as the reporting mechanism. But I am having trouble in getting Delphi to pass a parameter to the report. Does nayone have any suggestions? Thanks.

Can anybody please explain why Findfirst, when searching for *.htm will also find .html etc. and what please is the workaround. Was this designed for dos only when there were only three letters?, The real problem is that many web sites include duplicate files one for each of the extensions. Passing the output of Findfirst to a Stringlist with duplicates trapped will not of course solve the problem., Hopefully thanks., Don

Is there a Delphi component that can read the old Borland Database Toolbox files - it was a superb fast DOS database and I want to develop a reader for some old data going back to 1978!, , Thanks, , Michael Jarmulowicz

Can anyone give me an explanation as to why the following first assert fails? (i use D7), , var dt1, dt2: TDateTime;, begin, dt1 := Now;, dt2 := IncHour(dt1, 1);, Assert(HoursBetween(dt1, dt2) = 1, '1st assert!');, , dt1 := Now;, dt2 := IncHour(dt1, 2);, Assert(HoursBetween(dt1, dt2) = 2, '2nd assert!');

Is there a free unit, component or tutorial for creating PDF files? I only need very basic features. Just be able to insert some simple text and pictures in a PDF., If somebody has experience with a good commercial PDF product, i also like to hear.

I have a program that does a lot with strings, and is required to work everywhere in the world, so also in Asia for example. What is the way to do this in Delphi? Only use the Ansi... string functions? If i understand correctly the default string type should support this. If i write code like, , var SomeString: string;, SomeChar: char;, begin, if SomeString[1] = SomeChar then blablaDoes this work in other locales? If not how to do this? How do i get the length of a string (in characters)?, , If i understand correctly the only reason Delphi is not 100% unicode is because it would break Win9x compatibility. Please go ahead Borland! I don't want to worry about this crap...

I am looking for an easy way to read a users input from a badge. Inbedded on the badge is a CNTRL O to confirm that the badge is being used. So a typical response would be 1445 CNTRL O. After I know the badge is used, I just strip the 1445 and apply it to the job database. , My confusion is the vchar and vcharcode. HLEP, , hr41pearl

Unfortunately, I hit a compiler error I don't know how to go about it., , var, ShowThisForm: TForm ;, , begin, for i := 0 to ComponentCount - 1 do, begin, if Application.Components[i] is TForm then, begin, if FrmNam = Application.Components[i].Name then, begin, ShowThisForm := Application.Components[i] ;, ShowThisForm.Show ;, exit ;, end ;, end ;, end ;, end ;, , end ;

i want to read 1 2 3 4 or something of that format, four integers with a space inbetween from a text file. Once read i need to store each integer into an array so that it can be used later. How would i do this as i have tried many different ways and none seem to work. So for example , myArray[1]=1 , myArray[2]=2 , etc but it ignores the spaces
