Dev is acting weird

[Anubis208]

WinXP
4.9.9.2

Several strange things are happening with devcpp. The area to the left of the code typing area is gray, not black like it normally is, also when I select code, it selects in black, not blue.

(Code in screen shot is not what is causing it to act up, it is just for selecting)

When I tried to compile code with the use XP theme box checked under the compiler options the project compiled, but the window was not shown (I haven't tried it before until then, so I don't know if it was directly related to the other problems). When I copied the code to another project it ran fine.

Devcpp also does not recognize installed packages. I will download and install packages, but devcpp will not recognize the files from them. I can open the various package header files in the editor and they are normal, but devcpp claims it cannot find them when I include them i the project.

Is there any way to solve these problems without a reinstall?

What is weird is that you are the second person to complain about the gutter being grey rather than black, when grey is in fact the default. Either way the solution is simple: http://sourceforge.net/forum/forum.php?thread_id=1824743&forum_id=48211

I am not sure why your gutter has no line numbers - presumably it has been set to grey-on-grey.

All the other colours can be set in the same dialog. From memory I think there are a number of predefined schemes, one of which is the default.

With respect to using packages, I suggest that you need to post the build log showing these problems. Be aware that header files are not libraries. Including the header alone is insufficient - you have to explicitly link the library as well. You also have to tell the compiler where to find headers, and equally tell the linker where to find libraries. This is done in the Project->Project options->Directories dialog.

Many Devpaks come with project templates (File->New->Project) that set up the compiler and linker options appropriately.

With respect to the "use XP theme box" I'll have to take a look at that. The simple answer is don't check it!

As Clifford stated, for your package difficulties, a test case with your full Basic 3 is always
the way to go. Top level descriptions do provide context, but real data that can show exactly
what you are doing and seeing helps a LOT more.

Note that many packages come with project templates that are installed with them, such that
when you create a New:Project, there is an option on one of the tabs for, say, a GLUT
project.

I've had problems when using XP themes,i.e. buttons not being visible,edit box problems,ect.,and what I do is add:

define _WIN32_IE 0x0500

include <commctrl.h>

with my other includes and add -lcomctl32 to linker options.
I don't know why,but it works for me.

I forgot to add this in the WM_CREATE case of the WindowProcedure
INITCOMMONCONTROLSEX iccx;
iccx.dwSize=sizeof(INITCOMMONCONTROLSEX);
InitCommonControlsEx(&iccx);

That method works for using xp theme. I fixed the colors, but one weird thing; when you click in the gutter, or when the compiler detects an error an highlights it with the check mark in the gutter (I'm assuming this is an error line) no matter how much i change its settings, it remains a black select. Also for downloading packages, I have recently downloaded and installed a NeHe OpenGL Template. When I go to create new project, it doesn't appear under any of the tabs.

You are dealing with multiple problems in one thread which is a recipe for confusion. I'm confused already.

As has already been said; some but not all DevPaks provide templates. As I said earlier, posting your log will enable us to tell us exactly how to solve your problem. I have already given it to you in general terms - you need to link the relevant libraries. If you cannot provide the necessary information when asked what are you doing here!?

With regard to the selection colour, have you modified the correct colour setting? It is not teh same colour setting as for the gutter. That is so obvious I shouldn't need to say it, but your description of the problem is vague and ambiguous.

>> "...recently downloaded and installed a NeHe OpenGL Template..."
...tells us nothing without a link! We could Google, but we shouldn't have to. If it does not produce a new project type in the File->New->Project dialog, then it is not a DevCpp template (or you have not installed it).

Here, I will list all of the current problems I have now:

I have modified the color settings for the error line, but it still appears all black.

I have downloaded and installed (with the check for updates/packages on the tools menu) a NeHe OpenGL Template. When I create a new project, it is not a template option.

Another example that is similar to the above is that Devcpp complains of missing files for glaux (which I have downloaded an installed in the same way).

You installed Dev in "My Documents"? That is a VERY VERY BAD idea! Horrendous actually.

As is mentioned in the "Please Read" thread, spaces cause a lot of problems. Didn't
you read that?

Do a clean uninstall of Dev - see the Please Read thread for directions - NOTE CAREFULLY
the directions for keeping track of an reporting EXACTLY what you did. Then install
Dev where it wants to go.

In general, unless you know a program really well, it is a VERY bad idea to override
where it wants to go. It knows better than you do where it needs to go.

That's extremely weird, I installed devcpp to the default directory if I go to C:/Dev-Cpp I find it, but also, if I go to the My Documents folder I find the same thing, very strange. I am going to reinstall, I think that's the only way to fix this particular problem. Thanks for the help.

Did you relocate your My Documents folder at some point? I've only messed around with that in Vista but I think you could do it in XP too. That might make it appear to be in two places even though you installed in one. At least that's how it works in Vista.

[Wayne Keen]

Please make sure to get a clean uninstall.

Please

I reinstalled successfully (to the default directories) and now every thingworks fine, I redownloaded the packages I want, and there are no problems, thanks again for the help.

[Wayne Keen]

Super! Glad to hear it.

Giving away all of my tricks, let me encourage you to get in the habit of
looking at your Compile Log - even for cases where everything is working just
fine.

Knowing what things look like when they are right, and when they are wrong
can really pay off - and I am living proof that its not that hard. ;)

Note that you were asked twice to post the log (as well as it being requested in the "Read first" thread). The problem was identified in the first response following the posting of it (in a couple of hours). Which is exactly why you were asked.
