Is it not possible even if the restore point has has no system files (d:\, e:\ etc)?
Regards,

Unlikely. The files might still be in use, or the state of the system might depend on their contents.

Hi all,
I have started a project for an IDE using MFC Visual Studio Style Project.
I want to change the standar title of the FileView pane.
for this I changed the IDS_FILE_VIEW text.
But the result is not like expected.
On initial startup at top of the pane the new title is displayed correctly, but at button tabs there is still the old name "File View".
And if I switch between the tabs, the old name is displayed on pane's top too. In the whole project I cannot find other locations of the "File View" string, therefore I do not have any idea, how to change the behaviour!
Any ideas?

Basically code is from previous project my tutor helped me develop unfortunately I can no longer contact him, but I'm working on similar project which I did a simple object that moves around on screen, I pasted a pre-existing Direct X tool kit that my teacher gave me and imported it in as a project and did the linker with my other project but it's giving me the linker errors. Please kindly fix this there's no coding errors, also if possible please explain with screenshots what was wrong so I would remember for next time, thank you.

No. Please at least post these "linker errors" of which you speak. Plus which compiler, OS, etc. you are using.

From the first line, it looks you need the DirectXTK[^]. I see no prebuilt binaries there, probably you have to build it yourself from the sources.
|
|
|
|
|
Correct, I built it myself, can you show me or guide me on how to build it?, I need the simplemath.h files also included.
|
|
|
|

I would read the provided 'documentation', that is the Readme.txt file.

Hi all,
I am starting to create a framework/IDE for special type of project files.
The GUI like Visual Studio would be perfect for my needs and it can be easily created wih assistance from MFC Application Wizard (Options: "MFC" + "Multiple Documents" + "Doc/View Architecture" + "Visual Studio Project Style")
But this solves only the "surface"...internally I need another structure...I have only one document, but I need to create a bunch of views for the document.
In the "File Explorer" view there should be viewed the structure of the document and in the child view area there should be viewed all views (like the "Tabbed Documents"), related to the document.
But I have absolutely no idea, how to solve this!
Are the any examples, I could use as templates? Or are there any general ideas, how to solve?
Many Thanks
Richard

When you create your project you select a CView derived class for the view of the document. You can add more different views or create some of your own. The MFC templates have a few options if I remembr correctly, and there are samples in the MSDN website and elsewhere[^].
|
|
|
|
|
yes, you are right. I have overseen this!
When I create a MDI application, I am able to create several views by default already.
Actually my application should act like an SDI application. One document, on which I have several views. But when selecting SDI style in VS Project Wizard, I do not have this "tabbed document" style, which I would need.
In the case I am using MDI style, my challenge is now, to manipulate the MDI behaviour, that it acts like SDI.
A bit weird, but seems to be the fastest approach.
If this approach is reasonable, I should create a new thread for it in the forum....

I am stuck again.
I have inherited this piece of code which basically associate SAM3X8E pins with hardware registers.
I think it is pretty clever usage of array of struct and it works fine.
The original code did not include convenient way to access ALL of the registers, so I am trying to build the missing registers from basis assignments.
The registers are related to "port" ( designated PIOA.. thru PIOF) so if I can get the port assigned to a pin I can build all of the missing registers.
Here is the code to get the the port info from first (test) pin:
P_DB is a pointer to pins array.
( I have left all of the support code here FYI )
....
regtype TEST = *P_DB.pPort; *p_DB[0] fails same way
//lcd_i2c.print( (int) P_DB[0].pPort, HEX); // test access first pin
...
Now here is the error message from compiler ( on TEST) and I have no idea how to fix it:
C:\DOCUME~1\Vaclav\LOCALS~1\Temp\build6265730787782115322.tmp\sketch\AAA_TFT_LCD.h: In member function 'void TFT_LCD::LCD_Writ_Bus(char, char, byte)':

regtype TEST = *P_DB.pPort;
The error on (int) P_DB[0].pPort, code is pretty much same.
I hope I have provided all of the info necessary so someone can suggest a solution on how to access the pPort member.

Firstly (and not for the first time) please put <pre> tags around your code so it is easy to read, (use the <t style="background-color:#FBEDBB">code link above the edit window) thus:
regtype TEST = *P_DB.pPort; *p_DB[0] fails same way
As to the error, you have Pio* pPort; in your structure, but you are trying to assign it to a regtype variable, so it needs a cast, or some conversion to the correct variable type.

Thanks, but I found I already have the port data and do not need the access to the struct after all.

I am trying to build SAM3x8E registers database.
I though I could use serial of #define(s) to do that but run into a problem
In this sample I can build PIO_SODR but I cannot add another (port) offset to it - see PIOA_SODR.
I think the problem is my defines are not really int (32 bits) , but only symbols.
I did compare the (symbol) PIO_SODR to its true hex value and it failed.
BUT - I can add the first offset of 0x30 no problem. Ether plain add (+) or (|) or works.
Any help would be as always appreciated.
#define SAM_MSB 0x400E //MSD upper 16 bits byte base
#define SAM_LSB 0xE00
#define PIO_OFFSET 0x200
#define PIO_SODR SAM_MSB << 16 | SAM_LSB + 0x30 // base plus reg offset OK
#define PIOA_SODR PIO_SODR + 0x200 // add in another offset fails

#defines are not even symbols - when the pre-processor runs it replaces the #define "tag" with the associated text. You probably want to add brackets to the PIO_SODR and PIOA_SODR definitions
e.g.
#define PIO_SODR (SAM_MSB<<16|SAM_LSB+0x30)
#define PIOA_SODR (PIO_SODR + 0x200)
|
|
|
|
|
I think I got part of the answer - I am mixing logical operations with math so that is why the first #define works ( compare to value) AFTER I added brackets.
#define PIO_SODR (SAM_MSB << 16 | SAM_LSB + PIO_OFFSET) now passes the value test OK
#define PIOA_SODR (PIO_SODR + PIO_OFFSET)
But the additional offset does not work, but I am getting closer.
Thank for your help.
And it also helps to check if my #define(s) are not duplicated somewhere else !!!
Thanks

Mainly because the "core" program is build using defines and I am still not too comfortable using enum.
BTW after I "solved" this problem I have decided to "improve" on on it a got stuck again.
Life is fun.

I can only agree with Carlo on this. More generally, whenever there is a suitable way to use standard language features instead of #define, use that standard language feature. Even if it means you need to type more!
Modern editors offer autocompletion that makes typing effort a non-argument! Moreover, code riddled with #define macros is much harder for editors to interpret, preventing it from offering correct and complete autocompletion lists. Therefore the use of #define has the very real potential to actually increase the typing effort by hamstringing the editors capabilities!
Besides, as you've already stated, #defines will just keep tripping you up. Most of the time it is due to their entire lack of context-related syntax checking at the time of writing. And sometimes it is because your macro name conflicts with another non-macro symbol in some totally unrelated part of the code - that latter issue will lead to obscure errors that can keep you busy for days. I am speaking from my own experience.
Therefore: save time - do not use #define unless there is no other way to achieve the intended results. And if you do, don't place these macros in a header that gets included in unrelated source files - either put them right into the source file that needs them, or, if there are multiple source files that need them, put the macros in a separate header just for that purpose.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
