    Have you checked the Windows API help for getting all top-level windows? Cheers

    Stand alone unit

    The DPF file is, in fact, a unit. For form-based window applications, its job is to create the main form (and other autocreated forms) and call Application.Run. For console applications, you can put any code you want after the 'begin'. Try File | New | Other | Console Application. As for your...

    Word search special character for cells ?

    I want to remove trailing spaces from text inside a table. Outside of a table, I use FindText:=" ^p",ReplaceText:="^p", but as the delimiter for cell data is not a paragraph mark, I don't know how to phrase it. Cheers

    Word search special character for cells ?

    I want to search and replace in MS Word using their special characters to indicate the edge of a table cell. ^p stands for a paragraph, but that does not work (regardless of what RTF looks like). Cheers

    Mass database SQL INSERT - best way

    Aside from using a DBMS-specific command (e.g. LOAD) and INSERTing data from other tables, you have to insert things one row at a time. However, you can use query parameters instead of composing the text lexagraphically: with ThisQuery do begin SQL.Text := 'INSERT INTO ' + TableName + '...

    FormatDateTime not inserting leading zero

    While you are searching, insure the correct result: DecodeDate(DateTimePicker1.DateTime, ThisYear, ThisMonth, ThisDay); sMonth := IntToStr(ThisMonth); if ThisMonth < 10 then sMonth := '0' + sMonth; Cheers

    Freaky GroupBox caption problem

    I do things like SetLength(ThisString, 1000); // call an API function that stuffs something in PChar(ThisString) SetLength(ThisString, StrLen(PChar(ThisString))); Cheers

    Help with TRY...EXCEPT...END; statement

    I don't understand why you need two (2) try..except blocks. while not RS.EOF do begin try ItemList.LoadFromFile(SomeFile); // do other things except // don't care what went wrong end RS.MoveNext; end; Cheers

    Searching using Stored Procedures

    If you are asking how to communicate between forms, try treating the form as a class (which it is). Add a property to the form class itself: type TForm2 = class(TForm) ... // stuff that the IDE automatically puts in private function GetSelectedValue : String; public...

    Classes in Delphi 7

    You also might want to put the keyword "private" at the top so it would look something like this: type TModule = class(TObject) private StudentName: string; .... The "TObject" thing is implicit, but I like to put it in to make it clear what I am descending from. Another...

    Hierarchical Map From DTD

    http://www.intsysr.com/dtdchart.htm has one. It looks great, but my irrational aversion to Java (and VB) will be my downfall <s>. If you find a different one (i.e. native Windows), please let me know. Cheers

    mailto: via AOL ?

    Can one configure AOL to handle "mailto:..." requests? Has anything changed since thread605-90409? Cheers

    Access same POP3 account from LAN or Dialup connection

    I've seen suggestions to have two different log-ins. You also could try to have two different desktop icons and specify the profile in each (I think that different profiles can have different connection configurations). Cheers

    Db table Null fields?

    Note that MS-SQL will return .IsNull = False for VarChar fields even when the column has never has anything assigned to it; you have to check .AsString <> ''. (Also note that FieldByName is a function and uses parentheses not square brackets) Cheers

    How to find out whether any file is in use or not

    try TFileStream.Create(AFileName, fmOpenRead + fmShareExclusive).Free; except on E:EDontDoThatError do begin Someone is using it. end; end; Cheers

    DLL as a resource

    You would have to write it from the resource to a sepearate file on disk, and then call it. Cheers

    How do I cast a dynamic array of type Char to a string?

    You might try AString = String(PChar(ArrayOfChar)); Cheers

    Drag and drop help

    One rarely calls event handlers directly. I think you would assign a method to the OnMouseDown event handler that stores the most recent click to some TForm fields, and then reference those fields in the DragDrop event handler. Alternatively, you can use the Windows API to get the mouse...

    Send Password to another App

    I assume you cannot modify the other application. You can get the handle of the other application using Windows.FindWindow(). Then you can iterate through the child windows using Windows.GetWindow(). Windows.GetClassName() can identify the edit, and you can SetWindowText to it. Cheers

    How do I detect if BDE is installed?

    You can test for BDE in a launcher app and, if it is present, call your real application. One way to test is to explicitly load the BDE DLL (IDAPI32.DLL, I think) using Windows.LoadLibrary. Cheers
