ShellExecute in Delphi — Launch external applications. The function returns an integer that corresponds to an error code which is very useful when we need to show some status if the function worked or not.
By using ShellExecute we can also do following operations Can print documents from within my program, without explicitly starting the application that created the document, such as: print a Word-document without starting Word.

To develop a software like CAD, Paint, CorelDraw Delphi provides large number of classes and members that supports to draw shapes on a form or on a graphic control.
In Delphi, we draw shapes on canvas of a form or graphic controls. Canvas is an area of form where we can draw shapes, lines and can fill colors on shapes. In Delphi, every form or graphic controls have Canvas property which provides TCanvas object that can be used to draw shapes. TPen object is used to draw lines and we can set size, color of lines. TBrush object is used to set color and style to fill the shapes. Post as a guest Name. Email Required, but never shown.

Project options set in IDE ignored I encountered a weird problem after installing D on a new laptop. After setting it up and installing necessary components, I checked out a fresh working copy, but encountered compilation errors. First it seemed not to "see" the search path in project options. I could not figure out why, but "solved" it by moving it to the global library search path.
After this one I got another compilation error: after investigating it turned out that it was caused by missing conditional defines. I the parameters of the compiler on the "output" tab and it confirmed that th What is the problem?
I suspect that you have answered your own question, but cannot be sure without seeing the code in AppName. Jesus, don't you guys check this stuff before you send it out Options, options, options The component should be the same, i.
Ok, the same as the Delphi dialog. It would be Delphi IDE corrupts project file? I did a build and maybe an install on a Delphi project that is not a design time project. The units in the project have disappear twice now after building the project. I let Delphi convert the project instead of creating a new project and adding the units. Has anyone else had project corruption problems with Delphi ?
