>We are also toying with Rave report instead of RTF as Rave apparently can output a PDF quite easily. [wp] I think you're on the right track - turning to a reporting tool.  Rave might do the trick, but I've found it kind of hard to work with. I haven't tried to do exactly what you're describing, but I'd be very surprised if my favorite reporting tool couldn't handle it: Fast Report.  Fast Report also does a fine job of producing PDF output.

Can someone help me with a little problem I'm having? I need to copy the text values from the main nodes in a TreeView to ComboBox items., I know the code below will add a single node :, Form3.ComboBox1.Items.Add(TreeView1.Items[3].Text); And I tried using a 'for' statement and replacing 3 with i, but i keep getting an invalid index error. Plus that would add all nodes, and I only want the parent nodes.

I have been meaning to ask this for some time, however here it is., , What would be the accepted way of modelling an application that would have to deal with data on an annual basis. Let me try and explain, take for instance something we all know, the dreaded Mast demo application that comes with Delphi. This seems to do many business type things - but what it does not do is to allow the user (and customer) to start each financial year with the same customer base and a clean slate as regards individual customer data. And, of course, still allow previous annual records to be called up., , So what is accepted plan to produce something which does not lump all the data together in a never ending period. I hope I have explained this so you can understand the question , , rt, p.s. - why do the instant Graemlins stop performing when I use one?

Is there anything special I should bear in mind when trying to rebuild an application which has become terminaly ill. I am left with some quite useable forms including tables and the datamodule. , , Should I be doing things in a particular order? For instance, starting with a 'new applcation' and then adding the various bits to it, would the datamodule still function? Etc..., rt

i am writing an application that includes a log of the processes completed. i initially used a memo box and would just write strings to it as the program progressed to completion. this worked fine, until i decided i wanted to bold some commands and put others in italics. so i used the richedit box instead of the memo. the problem i have now is that when i get to the bottom of the box, the scroll bar appears but it doesn't follow the last entry (ie, once you get to the bottom of the box, you have to manually scroll down to see the last entry). this was not the case with the memo box. , , what i was wondering was if there was any property i could change about the richedit component to get it to "autoscroll"? if not, is there a better component that i can get that will allow me to change the text properties on a line by line basis, and "autoscroll"?, , thanks,, andy

I am using a DBCtrlGrid to display several records on screen at once. The control grid has a DBCheckBox and a DBEdit on it. I am trying to control the Visible state of the DBEdit according to the Checked state of the DBCheckBox., , When a checkbox is clicked (I am using the OnClick event), the corresponding DBEdit behaves correctly, however all the other DBEdits (for the other records) change state whenever I move to another record. , , I notice that the controls placed on a DBCtrlGrid actually appear with the Form as their parent in the object inspector., , Is there any way to determine which instance of the controls I am dealing with at any one time and limit the effects to just one record at a time., , Thanks for any help, , RonR , --------------------------------------------------------------------------------

I have noticed of late that when firing up Dephi6 (without even loading anything to work on) that almost 50% of the computers resourses are immediately used, which leaves very little for any programming work before the 'low resource' warning appears. On exiting Delphi the available rescources will increase., , I don't recall having changing anything to effect the machines staus quo, which normally runs with around 80-90% capacity., , Any ideas what's happening?, rt

To those new or converting to Delphi and its ineptetudinous OnLineHelp featuring so few useful examples, do not despair. I found whilst trolling around cyberspace the other day a UK university site offering excellent Delphi training materials including a downloadable 200 page book which includes what Borland should have included - a chapter full of examples on the mysteries of error messages. I know there is an awful lot of Delphi tutorage floating though space but I felt this really deserved a mention., , So, if of interest take yourself to [URL=http://www.leeds.ac.uk/acom/teaching.htm]www.leeds.ac.uk/acom/teaching.htm[/URL] , rt :)

Hi all, , I'm having a few problems accessing mysql from within a DLL. , , I have a mysql object, which simply wraps all the mysql funtctions (using libmysql.dll) in to a nice object., , I have defined an instance of this object as a global within another DLL. The problem is that multiple threads that call this DLL have to access the mysql object. How do I ensure the object can handle this? Currently the app crashes sometimes if two threads try to access the DLL at the same time (as they both try to access the mysql object)., , I would rather add code to the object then to the parts of the DLL that use the object, but any advice is good!, , Cheers, Pea

Hi , , Anyone had any experience with TWebActions? There is an html response field in which you can set the content to be sent back to the browser. This has the form:, , resonse.contentType := 'Text/html';, resonse.content := 'page content.......';, , My problem is that the 'content' is created by another app, which spits out the headers as the first part of content. the 'response' field, if given no headers, seems to stick its own content type header in, and thus my additional headers are simply displayed to the screen., , I can parse the headers out of the content and add them to the response.headers, but I have a feeling that perhaps there is some way to set a TWebAction response to output the content 'as is' without additional headers?, , Cheers, Pea

Hi all, , I'm creating an ISAPI extension using a TWebModule, but can't save anything to disk from within it. example:, , stringList.saveToFile('name.txt');, , Won't work, but if I put as the file name 'c:\name.txt' it will., , My problem is I need to know the directory in which the dll resides when it is running (for loading ini files etc).

Hi all, , I've had a bit of trouble setting up local variables in a dll. The problem is that my dll is accessed by many threads at once. I am able to create a global variable that every thread can access and alter., , I have read about threadvar's - and the help says DONT use in DLL's., , Is there a way I can define a local variable within a DLL (initialised in the DLL_THREAD_ATTACH routine perhaps) which has a seperate instance for every thread which attaches?, , Perhaps the only way to do it is to have a global stack (or array) of pointers to these local variables and to keep a record of which stack element each thread uses?, , Any ideas?, Pea

TComponents are streamable because any object descended from TComponent is able to be directly streamed to memory using the TSreams/TFileStream/TMemoryStream feature:, stream.writeComponent(TComponent);, , This (supposedly) allows any component you write be streamed to file (or memory) during run-time and be loaded again (using 'readComponent'). This is what I know., , The prob. is that I've heard it mentioned that any objects your component owns (sub components) do not stream easily, and may not work well., , If anyone has succesfully created any type of class, filled it with data, and streamed it straight to file using 'writeComponent'- please advise me on how you did it 'cause it would be very helpful!!, , Thanks, Pea

Hi,, , I'm using the Indy component IdHTTP and want to display the header returned from the server. In the "help" I only see the header contents exposed as properties, one for each value. I find that the properties reformat the content also, eg, date strings get converted to date objects., , Does anyone know how to bypass the properties and access the raw header?

I would like to know if there is any problems with Microsoft SQL 2000 and the BDE. My company just purchase SQL 2000 and we use Delphi 5 enterprise edition, to hit the tables. I am trying to narrow the problem down to see if it the BDE or SQL 2000. Here is what happening, I can setup a alias through DBExplorer ok, and actually see the tables, but I don't see Foreign Key or Primary Keys, Referential , Unique, or Check Contraints. Also I have loaded the driver for SQL 2000 from MS SQL 2000 CD and our DBA has doubled checked and can see the Contraints on his side. If someone can help me or steer me in a directions where I might find a answer I would greatly appreicate it. Oh yes we are running BDE version 5.1.1
