Solved installation Repository Corrupt - by: robert

Below is my post that I was posting regarding how I screwed up the installation. Long story short: The file repository in \ public was corrupt. I uninstalled and then manually deleted the repository and then installed platforms one at a time,



..........................................................................................................................................................................



I am being unsuccessful at installing the free trial of Delphi/Rad studio.... I am going down hill. My first attempt. I neglected to select android, which is the primary purpose of this trial. Rad studio was working but obviously not giving me what I needed.

Then I made a crucial mistake. I went back and ran the installer again, thinking that it would pick up the components that I failed to install.. it got to the jdk and android sdk and wouldn't get past that...Ahhh it must be that I have installed android studio and jdk previously.... removed them and tried again.. uninstalled Rad studio....spiralling down the tube....further and further.. YEAH I know I should have read the directions but not having to read directions has always been one of dephi's key advantages.

I tried to clean everything up and start from scratch... It installs the basic files but no platform support, even if I go in from the ide and tell it to just install delphi 32 for windows. I can see a page flip by before it says "operation error"..

Is there any log file that will give me a clue as to how to fix this.. Or any pertinent advice that is not "wipe system"

If I wasn't a longtime Delphi fan I would give up.

thanks

robert



I dug in and found the file,,, it doesn't help here is what is happening immediately before dying:

How do I change the background color in listview? - by: john

June 15, 2015, 2:12 pm

This is a firemonkey listview control.

I have a listview that retrieves info from an sqlite database.

And, I want to change the background color (say from white to yellow) based on a value in a query.

I searched google but so far have not found a solution. It can't be that hard to do, can it ?
Its gotta be hidden something like: listview.cell[0].background = clYellow

The listview is linked via LiveBindings, So I guess I will have to add a routine (never done this) to check through the list, testing for a value in the query and then change the background of any items in the list to Yellow and refresh the list to display.

Why I want to do this: because changing the color to yellow (or whatever color I decide) will help the end user to know certain clues about that item they are about to select, if it is yellow.

Thank you.

I upgraded to Windows 10 last week & now I cannot compile and run more than once or twice from the IDE without it locking my Surface 3 solid, until yesterday I was using XE7 pro but purchased XE8 thinking that it would solve this but it hasn't, if I compile from in IDE & then run the exe directly all is ok



I am on a deadline so haven't devoted much time to trying to solve it by uninstalling components etc and will do so later this week but I did wonder if anyone else getting this or is it just me?

hi,
after a clean un-install of RAD Studio 10.2.1, I installed the latest RAD Studio 10.2.3. At the end of the installation the program runs fine.

I'm using Win 10-64. I clicked on the link to download the Delphi Community edition and the installer was for Rad Studio. I received a license for "Delphi 10.2 Tokyo Community Edition" via email and that is properly installed according to the "Embarcadero License Management" app, but the license manager wizard keeps popping up with the message "No Valid License information found for Embarcadero Delphi 10.2.

How do I resolve this so that I can run Dephi Community? Do I need a separate serial number/ license for Rad Studio?

I want my code to read Button1.Caption. not Self.Button1.Caption. And I don't want to manually delete the "Self." after using it.

I'm using C++ Builder 4.0 to develop a program to read a database. (It's a older machine which RAD Studio doesn't work on, and I need to have the entire database read into memory. Its a small database consisting of less than 100 records)

I'm using GetFieldData("FieldName", Result) to read the records.
Regardless of what data type I set Result to, (I've tried AnsiString, char *, and void *) I get the error message " could not find a match for TBDEDataset:GetFieldData(char*, char*)
I don't want to use Lookup or locate in this instance, because all I want to do is read the database and I need to read the entire database.
