I have Borland CBuilder 5 working for a particular user on my computer. However, when I log in as someone else and try and open a (previously working!) project group, I get errors every time I try to open a dialog class file complaining of missing components... Class TPageControl not found...

Is there a way to assign an attribute to all items on a form in one go? For instance, I need to set the Font->Charset attribute for every item on numerous forms. I was hoping there'd be a quick way around this rather than assigned each item individually.

I've got two blocks of data (data and data2). I'm trying to copy both blocks of data back-to-back into a SAFEARRAY. The first block copies ok, but what should the parametres be in the second memcpy function? SAFEARRAYBOUND bound={dsize+dsize2,0}; psa = SafeArrayCreate(VT_UI1, 1, &bound); if...

...in this case Turkish! I have installed the Turkish character set on my UK computer and am able to type the full Turkish alphabet into notepad. However, when I try to type the same thing into an EditBox in my Borland C++ Builder program the characters don't come out the same. I can copy and...

I recently upgraded from Interbase 6 to Interbase 2007 and my program is much slower than it used to be when using the IBTable object. Specifically when I call IBTable->Active=true; Does anyone know why this is?

I am comparing two pointers. When debugging they both contain the same address (both 00E2A7DC), but my comparison doesn't return true. Why not? Graphics::TBitmap* Image1; Image1 = new Graphics::TBitmap; //point 'image1' to first image in 'ImageList1' ImageList1->GetBitmap(0, Image1); //add...

My program accesses two interbase databases with identical structures. I need to copy a selected record from a table in DB1 to the corresponding table in DB2. Is there a quick way to do this with TIBQuery? Or do I really have to write each field in DB2 manually from the query on DB1?

I am currently developing some software which is to be used internationally. I therefore need to be a bit clever with where my program reads/writes to files because locations such as "C:\Program Files" may not exist on foriegn systems. I have done a bit of research but am still a bit unclear on...

I have an interbase database with a table containing 3 fields. The DB has about 3000 entries. I have some code which should pull out half of the entries. I am timing this function using timeGetTime() and I am getting some very inconsistant results. Sometimes the function takes less than 0.1...

Is -+ a valid operator? I'm editing a program written by someone else and I have never come across this before. Could it be a typo? The instance is as follows: if(var1 && -+var2){ //... } Thanks for any help.

I have changed nothing in my (previously working!) code but I have come up against an error. My program compiles fine, but an error is displayed when it is executed: intf != 0 failed -C:\PROGRAM FILES\BORLAND\CBUILDER5\INCLUDE\VCL\utilcls.h/2868 I have no idea why this error has suddenly...

Is ther any way to make a TSplitter control immovable? Cheers for any help.

Not sure if this is a very good place to post my question, but I'll give it a try anyway. I've got a quick report form with various TQRLabels and a TQRImage. The TQRImage is to have a screen-dump bitmap assigned to it. I have coded this as follows... Graphics::TBitmap *FormImage =...

I have a multi-project workspace in Borland C++ Builder 5. One of the projects has a few .h files that have ALed.hpp as an include. This project builds fine. The remaining projects build fine too... except one. When attempting a build on this project, errors are found when trying to include...

The default tab size in Borland C++ Builder 5 seems to be huge (about 8 spaces). Is it possible to reduce this default tab size? It'd make my coding far quicker.

I have some code to edit which I don't fully understand. Here it is... struct TDelrecs_tbl{ int table_no; int pk1, pk2; }; void function1(void){ TDelrecs_tbl delrec; delrec.table_no=1; delrec.pk1=2; delrec.pk2=3; function2(&delrec); } void function2(void...

I've got a pointer to a double set up like this: double aValue; double *aValuePointer; aValuePointer = (double *) &aValue; I can pass this pointer to a function which expects a double using aValuePointer[0]. But the problem is I want to copy this pointer to a new one. I thought I could just...

I have created a combo box with five entries using the Object Inspector. I now want to dynamically add a 6th entry to the list from within my code. Any ideas how to do this? Cheers.

I know it is possible to change the value of a static label by: Label1->Caption="Some text"; But how do you change the content of a TMemo item? Thanks for any help.
