I need to parse a .dat file which contains hexadecimal data. I need to parse the contents and store it as a text file.
I have the .dat file and the header file. Can anyone tell me how should I start with it or what are the steps involved.

Depends on what the hex represents... is it ASCII? is it archived? Is there a certain algorithm encoding it?

the pseudo-code would be:
1. open the input file
2. create the output file
3. for each line in input file: read it, process it, write results to output file
4. close output file
5. close input file
6. terminate
However your description sucks a little, there is no such thing as hexadecimal data: all files contain either text or they don't; and every byte can be displayed as ASCII, Unicode, or be formatted in binary, octal, decimal, hexadecimal.
So maybe what you mean is: I have a text file containing a hexadecimal representation of some data, but then what would be the conversion you need, as it already is text?
So try to clarify; and to confirm your description, add a little example (input line, matching output line).

The .dat file contains few information as
path of a file,filename,date of creation of file etc. These information are stored as hex in the .dat file.
Depending upon the header file I need to extract these data and store it in a text file as normal text.

To further expand on Luc's answer from point 3 of "process it", you can use strtok_s[^] to extract hex characters from each line.

I have a skinned dialog that I am attempting to place transparent buttons on; based on CButton. However, when I do a create I find that a blank space is created where my button should be. Therefore the background that shows through my transparent image is white rather than the skinned bitmap that should appear. I imagine that the reason this area is not painted is because that area is to be painted by the button.
Is there a way to get that area of the background painted despite the fact that the button is to be painted there?
Thanks in advance.

(I assume that the buttons you are creating are subclassed CButton.) The white spaces is created by someone somewhere. Did you check your handling of WM_ERASEBKGND?
|
|
|
|
|
wm_erase_backgroud should return TRUE;
and show your background images in ONpaint method.
|
|
|
|
|
I do handle OnPaint, it was a silly misstatement. I am not sure what you mean by "show your background images in OnPaint method"
|
|

|
|
Make sure you don't have WS_CLIPCHILDREN specified for your dialog window.
|

I apologize if my attempt to be succinct ended up being unclear. I have looked into what each of you have asked.
@Mattias G:
Yes, it is a subclassed CButton. I definitely agree that this is being created somewhere, it is just the where I am having difficulty with. I've looked at the OnEraseBkgnd and haven't found anything out of the norm.
@shivanandgupta:
My OnEraseBkgnd does return true. I do not handle Onpaint method in my dialog.
@Niklas Lindquist
I do not have WS_CLIPCHILDREN specified in my dialog window.
I feel like this is actually rooted in how Create is handled by CButton, one of the window or button styles. I will write back if I find anything.

Dear what do you want pls tell me details
If you want customize button with some bitmap .
and your dialog has background Bitmap.
firstly you draw dialog bitmap in onpaint dialog.
and derived class button should also call own onpaint method with button bitmap.
|
|
|
|
|
I've found and am trying to implement the suggestion found here (CButtonST v3.9)
This basically states that I need to force each button to paint it's background after the OnEraseBkgnd is handled by the dialog by calling OnPostEraseBkgnd.
Working on getting this solution to function correctly in my code.

Am I the only one trying to use EWS from native code via the Windows Web Services API? The documentation seems to be virtually non-existent and I've failed to find any samples so far that don't use the Managed .NET API. If anyone has or knows of any sample code on the subject that they are willing to share, I would be very grateful.

This is nice introduction to this API here on codeproject.
Life is a stage and we are all actors!

nice try, but I think he was after help for Webservices layer to talk to Microsoft Exchange (Email) layer - which I guess is sort of a subset of general webservices, it just happens to be a very particular subset !

The Windows Web Services API is what I'm using to speak to exchange but I'm struggling to use structures and functions generated from the EWS WSDL file. I've had some success but it's slow going

I did have some articles and things I found on the Web (I'll try and find them) - there was an SDK MS published for this as well that wrapped the low-level web/soap stuff to make it a bit more friendlier (I downloaded the SDK but never really got into it)...
I found it much easier, to use the independantsoft http://www.independentsoft.de[^] wrapper (see [products/Exchange Webservices .NET) - my colleagues in another 'division' of the company currently use the WebDAV version for Exchange ?2003 which is how I found this - Im going up egainst Exchange 2007, and one of these days Exchange 2010 where WebDAV wont be supported - the first looks and kicks Ive had with the demo download look ok/useable
ps.. Im not affiliated with independantsoft in any way

The suggested wrapper is .NET based which is what I'm trying to avoid so any info you can dig up will be very much appreciated.
|

|
|
what version of Exchange btw ?
'g'
|
|
|
|
|
I'm testing against 2007 but I assume whatever I come up with will be compatible with 2010.
|
|
|
|

ko - we crossed messages (my fault) - see the Microsoft Exchange Server 2007 SP1 SDK - or use that as a search term in your favourite engine ...

How can I read /write an EEPROM on a PCB from my computer. Any help and or example plaese?
kd
|
|
|
|
|
is this an existing PCB? what else does it hold? is there a micro-controller? what kinds of interfaces have been provided? and what kind of EEPROM (manufacturer, model, capacity, databus width, timing specs, ...)?
or is this something you still have to design?
and what is it for?
