Has anybody been able to follow this and get it to work?  I'm having trouble and getting a error...
 
MyPanel.cpp(78) : fatal error C1010: unexpected end of file while looking for precompiled header directive
 
I tried compiling it after the modification to vgui_int.cpp when it says to run the game.  Anybody having the same problem or am I just royally screwing up?
 
[[User:Cpchang13|Cpchang13]]
 
you need to #include "cbase.h" [[User:Ts2do|Ts2do]]
 
== solution?? ==
 
This is how I solved the previous problem:
fatal error C1010: unexpected end of file while looking for precompiled header directive
 
<code>
#name your file '''CMyPanel.cpp''' not a '''MyPanel.cpp'''
#add following headers:
</code>
 
#include "cbase.h"
#include "IMyPanel.h"
using namespace vgui;
#include <vgui/IVGui.h>
#include <vgui_controls/Frame.h>
 
 
- comment following virtual functions (there is no implementation??):
 
// virtual void OnTick();
// virtual void OnCommand(const char* pcCommand);
 
:Warning: Commenting out 'virtual void OnTick(); will prevent you from making a console command for the panel. --[[User:Brad Newsom|Brad Newsom]] 18:45, 3 Jan 2009 (PST)
 
== IMyPanel.h ==
 
Why '''I'''MyPanel.h?  Why not just MyPanel.h?  Wouldn't it be less confusing if we took out the random insignificant things that make people needlessly wonder "why"?  Isn't it best to keep things simple and straight forward?  Especialy in tutorials?
--[[User:Gijimbo|Gijimbo]] 09:02, 1 June 2007 (MDT)
 
Ok so I'm guessing it's because they were following the "IClientPanel.h" and other "'''I'''blahblah.h" naming conventions.  But I still have the same question: why?
--[[User:Gijimbo|Gijimbo]] 09:20, 1 June 2007 (MDT)
 
Ok, what's the deal with IMyPanel.h in general, does it just provide a supporting class? Do all panels need an I(nterface)?
--[[User:TheDistur|TheDistur]] 21:53, 18 Aug 2007 (PDT)
:Basically, it's an include that gives the other source files access to the panel you've created. That's what the <code>extern</code> part is doing - giving any code that <code>#include</code>'s the file access to the panel. --[[User:Daedalus|Daedalus]] 02:28, 19 Aug 2007 (PDT)
::It just exposes the create(parent) and destroy() functions eh? If I have any more questions can I just shoot an email to the address on your user page? I don't want to talk about what might be obvious to most of you coders forever on the Talk page. --[[User:TheDistur|TheDistur]] 12:50, 19 Aug 2007 (PDT)
:::Correct. Basically, for a panel to be able to be used, it must be created (<code>mypanel->Create(gameParent);</code>) and to stop memory leaks, destroyed when no longer used. <br/>
:::As to posting further questions, I'd prefer if you asked the questions here, because other people might have exactly the same questions as yourself, and the answers would help them too. --[[User:Daedalus|Daedalus]] 05:32, 20 Aug 2007 (PDT)
 
== Calling the panel ==
 
Ok so after following the different bits and pieces of corrections and helps that you guys have offered, I finaly got it to compile.  Alas, the game menu was no different and "MyPanel" was nowhere to be found.  I have the feeling that the "calling the panel" section is what needs attention; serious attention.  If someone who has gotten the tut to work would post their whole modified '''working''' vgui_int.cpp file, I wouldn't mind revising the "calling the panel" section to make it more understandable/workable.
--[[User:Gijimbo|Gijimbo]] 09:08, 1 June 2007 (MDT)
 
I got the panel to show up but when increase the screen resolution the title of the panel becomes huge.  When I open the panel editor it's title and numerous other text areas are huge as well.  Any suggestions?  I'm guessing it's in one of the res files used.
--[[User:Gijimbo|Gijimbo]] 10:14, 1 June 2007 (MDT)
 
 
== Adding mypanel->Create(gameParent); ==
(This is Inside of Calling the Panel)
 
Where is this added? It just says "Add it after you include" (which never tells you what to include, I'm assuming were including IMyPanel.h)
 
Can anyone point me to what line or section it should be added into?
 
--[[User:Lord Ned|LordNed]]
 
== Menu Call Is not working ==
I followed this guide and added the code to make it called from a main menu option, but when I click on the option nothing happens, I just get the click sound.  Is the coding for Orange Box different somehow for menu calls?
 
EDIT:
 
I got it, keep forgetting my bins copy to a different folder then my mod lol.  Moved em over, added a few res files and now it works.
 
--[[User:Laughing Man|Laughing Man]]
 
== Calling Panel In game. ==
 
I have looked around and I can not seem to figure out where to put the code for showing the panel in game. Any help with this would be very helpful.
 
--[[User: Xioyn|Xioyn]]
 
== My panel won't show up in Debug mode ==
 
So...i created the panel, had a resource file for it and all that but, when i run debug mode, i get the console, bring up the
editor (Ctrl+Shift+alt+B) list the panel hierarchy and...nothing (i get the hierarchy but my panel doesn't show up anywhere in there). Does anyone have any idea why that might be happening? Sorry
for the novice question, i am new to Source SDK.
 
== error LNK2001: unresolved external symbol ==
 
'''.. have some errors on Visual Studio 2010:'''
 
Error 1 error LNK2001: unresolved external symbol "protected: virtual void __thiscall CMyPanel::OnCommand(char const *)" (?OnCommand@CMyPanel@@MAEXPBD@Z) C:\Program Files\....\client\MyPanel.obj Client Episodic

But I only have the two protected functions as error.

'''Quick Fix'''
 
This error is because you have told the compiler that you are going to override these functions (OnTick and OnCommand) but you have not provided any definitions. The linker can't find them because you haven't written them. Put a pair of brackets '{}' after the definition, or define the functions at the bottom of your panel cpp page. as in:
 
<source lang="cpp">
//CMyPanel.cpp
 
#include "cbase.h"
...
 
class CMyPanel : public vgui::Frame
{
    ...
protected:
    // VGUI overrides
    virtual void OnTick();
    virtual void OnCommand(const char* pcCommand);
    ...
};
 
void CMyPanel::OnTick()
{
    BaseClass::OnTick();
}
 
void CMyPanel::OnCommand(const char* pcCommand)
{
    BaseClass::onCommand(pcCommand);
}
</source>

Thank! But I still get the "error LNK2001: unresolved external symbol "class IMyPanel * mypanel" (?mypanel@@3PAVIMyPanel@@A) C:\Program Files\....\client\vgui_int.obj" error, Can anyone else help?

:That might seem a bit late since your post was 2 years ago, but I just had the same problem. In my case, that error showed up on the Episodic project, because I was working on HL2 only. After copying header and source files into the Episodic project the error went away. vgui_int.cpp is the same in both projects, but initially the external symbol was defined only within HL2. Hope that clears things up a bit. --[[User:ArmsOfSorrow|ArmsOfSorrow]] 16:39, 14 April 2014 (UTC)
 
== Panel wont disapear ==
 
I'm pretty sure all the codes in, the panel apears in game but if i assign a button with the command turnoff it wont disapear when i press it
 
==.res File Names==
In December 2013, the resource file had to have an all-lower-case name to get the VGUI Build Mode Editor use it.  If not, the editor would create an all-lower-case.res file and put its changes in that.  --dave
 
== Not able to load client DLL after finishing this tutorial ==
 
After I added the code from this tutorial to my mod and built it, the engine stoped being able to load my game DLLs.
I have no idea why this could be happening to me and from what I have seen, I'm the only one this seems to be happening to.
If anyone can help what would be great. -TwoTails
   
 
EDIT: I fixed it. it turns out I put some code in the wrong spot lol -TwoTails
 
== an error ==
apparently some command fails while compiling<br>
this is the full error:<br>
 
The command "if EXIST ..\lib\public\.\mathlib.lib ( for /f "delims=" %%A in ('attrib "..\lib\public\.\mathlib.lib"') do set valveTmpIsReadOnly="%%A"
) else ( if not EXIST ..\lib\public\. mkdir ..\lib\public\. )
set valveTmpIsReadOnlyLetter=%valveTmpIsReadOnly:~6,1%
if "%valveTmpIsReadOnlyLetter%"=="R" (
    attrib -r ..\lib\public\.\mathlib.lib
    ..\devtools\bin\gnu\touch.exe -d "1999-01-01" ..\lib\public\.\mathlib.lib
    attrib +r ..\lib\public\.\mathlib.lib
)
if exist "..\devtools\bin\vpc.exe" "..\devtools\bin\vpc.exe" -crc2 "mathlib.vcxproj"
if ERRORLEVEL 1 exit /b 1
:VCEnd" exited with code 1.
 
i am very new to this, can anyone help? -trolleybus
<br>
<br>
edit: apparently its not an issue with the panel code, i still need help though
 
== Potentially Too Verbose? ==
 
Some sections could be helped by removing unnecessary code blocks, and simplifying the instructions (and being more specific).
 
'''Instead of saying...'''
 
''Place this code''
<source lang="cpp">
void ArbitraryFunctionA( void )
{
    //something...
}
</source>
''Beneath this code''
<source lang="cpp">
void ArbitraryFunctionB( void )
{
    //something else...
}
</source>
 
'''It may be better to just say'''
 
''Place the following code beneath ArbitraryFunctionA( void ) inside RelevantClass()''
<source lang="cpp">
void ArbitraryFunctionA( void )
{
    //something...
}
</source>
 
Just a thought, since I got confused first time reading later sections of the tutorial.
Many pages suffer from this in my opinion, at least when it comes to people like me who easily trip over words, haha. I see that similar problems have come up so it does seem this page could benefit. --[[User:KaliDitzy|KaliDitzy]] ([[User talk:KaliDitzy|talk]]) 13:02, 21 December 2023 (PST)
