TRichEdit Scrolling Question2005-01-31 07:26:03 PM cppbuilder2 Hi All, This question may be the dumbest you have ever seen but for some reason I don't seem to be able to work this out ???? I have a Rich Edit on a form, it is set to read only, as serial data is recieved from the Comm Port I add this data to the RichEdit, when the Rich edit window is full it adds a scroll bar and the data dissapears off the screen. To view the data you need to use the scroll bar. What I want to do is have the Rich Edit automatically scroll with the data, for example if you had a list box and you wanted the same functionality you would have some code like the following void __fastcall TMainForm::AddSerialDataToList(String SerialData) { // Add Data to list ListBox1->Items->Add(SerialData); // if more than 1000 items are in the list remove the first // as we only need to keep the last 1000 items if(ListBox1->Count>1000) ListBox1->Items->Delete(0); // scroll list box so most current data is shown as it // arrives in the list box ListBox1->ItemIndex = ListBox1->Count - 1; } I am using a Rich Edit because I want to highlight the delimeters of the data that I have received as well as bad data and specific data streams in different colurs. Can this be done with a TRichEdit and if it can how? Many thanks in advance Joe |
