*(p - 1) = ' ';
will put a space character in the byte imedieatly preceeding the location pointed to by p. If p is a pointer to the location after your buffer, the last character of your buffer will become a 0x20 (space character).

Yes. That space however is going to the end of the wrong array, RadarParityTable. I have to parse another buffer, a file header, and treat the data differently when it encounters two spaces. Because strtok puts a 0x00 or '\0' at the end of each substring where the token exists, the data will be in EBCDIC when written to disk, I had to replace the spaces that strtok put into it. So, I did as you say put a space preceding the spot where strtok found the next substring of data.
I must be corrupting that memory somehow, though boundschecker active mode is not catching it. Its funny though that changing the size of the RadarParityTable from 4096 to 4097 fixed the problem.

Sorry, I didn't answer. I did not get to it but I believe that when I don't put the address of operator (&) it says something about parameter 1 not being right. That's why I used &RadarParityTable. I'll check again if I have time tomorrow. I know that parameter 1 should be a void pointer. Thanks

What error message does it exactly give ???
Using '&' is not correct.
Thanks,

You were right Ramu. I had gotten this msg earlier:
'memset' : actual parameter is not a pointer : parameter 1
but that was for a structure. So, when I coded the statement for an array I used the same technique. Now, I see the errors of my way.
|
|
|
|
|
BTW, The way I'm doing it now doesn't give me any warnings and when I breakpoint after the memset, the entire array is equal to zeroes.
|
|
|
|
|
I fixed it. Thanks, everybody. It turns out that on the very first call to strtok and all subsequent calls, I was placing the '\0' that strtok appends to each substring with a space. However, on the first call to strtok, there is no space (my token) before it, and thus I was placing a space into a memory address where my other array's end element existed.

Hey everybody, I put a post out about my word automation not working. I haven't been able to get past the Link Error so I tried something different. Now, I have this function which puts a button (with a bitmap) onto MS Word. As you can see, I create it dynamically. Now, what I was wondering, how can I capture the event when this button is pressed? I am trying to do an Advise but it doesn't seem to be doing what I want it to do??? I have pasted the header file for the event sink and the actual function which does the Advise. Any ideas? Anything come to mind? Do you think I am making this too complicated and have a better way to go at it? Just let me know, I am knew to COM/ATL/OLE development...

You have to advise the button events (_CommandBarButtonEvents) from m_pButton and add event handlers to the sink map.

I created a stand alone MFC dialog box. After debugging I noticed that m_hWnd is always NULL. I'm trying to get the handle to the dialogbox.
Thanks

This handle will be null until you create the dialog with Create or indirectly with DoModal ---having the CDialog constructed does not suffice.

I am receiving data from a socket server (QNX based) into a VC++ DLL. the data is in the format
struct Data {
short num;
unsigned long value;
char name[33];
}
I am receiving a message containing large numbers of these data strucutres. I can store them fine in my DLL, i have adjusted the byte packing and everything works great. Now, I have to move the data from my DLL into Visual Basic. I have read competing articles (by microsoft) on the proper way to fill a UDT Array passed from vb. I have tried many things including the use of a Type Library.
I would like to pass in a reference to the UDT Array from VB to C++ DLL, and populate it with the data i received from the QNX process. I am having trouble with both fixed strings and variable length strings. Please help. Please Please Please help. This has gotten very frustrating..
Any Help would be greatly appreciated.

I am currently having trouble with MFC
What I am trying to accomplish is as follows; When a user double clicks the mouse on a section of the dialogue window a bitmap would be displayed at the location of the doubleclick.
The Problem; I cant seem to find any code that would allow me to do this. All code I have found either loads a bitmap when the window is created or will not funcion in a dialogue window.
This is my first post here at TheCodeProject. If I did not post in the right place or did not follow a proper convention please let me know so I can remedy it.
Thanks,
Eric

Wow - are we that scary ? You've done well, you've found the right spot. Welcome to CP !!!
You need to load the bitmap into a member variable, then on double click draw it in the correct location. You'd therefore need to store a point to represent where the thing is drawn, and maybe initialise it to -1, -1, and draw only if it is positive numbers, so it appears on the first double click and then moves when you click elsewhere.

Thanks for your quick response.
Just repeating my interpretation of your response.
So make a local var of type CBitmap then map "double left click" and in that function use the CPoints X, Y coordinates and draw the bitmap at that location.
Using the bitmap, (and I think DC mem as well) how do I think display the bitmap?
Do you have a link to some sample code I could look at?
Thanks again for your help

No, you need to store the location as well, so it gets redrawn when the window gets moved, etc.
EBerlin wrote:

In OnEraseDC, call the base method first, then draw the bitmap. Yes, you'll need a memDC to hold the bitmap while drawing

Sorry, no. But if you give that a go and get stuck, I'm happy to help.

Does anyone know what the format of the Outlook Express storage file is or where to find the format for it?
My problem in a nutshell is this: I want to be able to filter out all of the spam emails from my Hotmail accounts. I've looked around and tried many of the shareware/trialware programs out there that claim to do this, but have had no luck with them working. So, instead of trying to find a program that does what I want, I'll have to (try) write one instead. The only problem is that I don't know the format of the DBX files that Outlook Express is using.
Before I spend a lot of time trying to figure out the format by example, I thought I'd see if anyone here knows what it is of has seen it described anywhere. What would be even better is if someone has already written a class that handles this (though I'm not too optomistic about that).
So, can anyone help me with this?
Thanks in advance for any help or pointers!
Mike

Thanks for the response!
If you could post some of the URL's that would be great! I've searched many different times and didn't find anything that I thought was useful. It is entirely possible that I didn't search with the right keywords or that I just overlooked articles with the relevant information.
Thanks again!

can't help with the DB layout.
but, IMO, it's probably easier to go at it at the source - at the mail transport level. i think Outlook Express supports MAPI. if so, you could write an app that scans your inbox looking for files that match patterns, and delete the ones that do. this app does something like that: http://www.smalleranimals.com/snoop.htm. it's not too complicated to do.

Thanks for the reply Chris!
After seeing the great (and daunting) data that Ernest posted, I am beginning to think you're right.
I was hoping for something that I could do in a couple of days (it doesn't have to be pretty, it just needs to work) but this has the appearance of a full fledged, several weeks project. More time than I want to put in, I think.

File format for Outlook Express 5.0 DBX files
Header:
These are the values we use to see what type the file is.
0x0 Signature [16/32 bytes]
= 4A4D4636 03001000 /* OE4 SIGNATURE */
= CFAD12FE C5FD746F 66E3D111 9A4E00C0 /*OE5 Email DBX*/
= CFAD12FE C6FD746F 66E3D111 9A4E00C0 /*OE5 Folder DBX*/
As I said, we use these values to identify it, but we don't know
what these values mean
0x5C Highest Email ID [4 bytes]
This is the current highest. The next email will have a number
one higher than this.
0x7C File Size [4 bytes]
Total size of file
0xC4 Item Count [4 bytes]
Number of items stored in this DBX file. Appears to be
accurate. We use it as a second check that we haven't gone wrong
whilst reading the indexes.
0xE4 Index Pointer [4 bytes]
File offset pointing to a page of Data Indexes. This page can
even be a page of Indexes pointing to pages of indexes. This area
needs to be explored a little more
Indexes: (pointed to by the pointer in 0xE4)
This area is a little blurry, but it appears to work
0x0 Self [4 bytes] - Current Offset
0x4 Unknown [4 bytes]
0x8 Table Pointer [4 bytes] - Pointer to another of these tables
0xC Parent [4 bytes] - If this is a table of indexes which is
referenced by another table above it,
this will point to the parent's table
0x10 Unknown [1 byte]
0x11 Pointer Count [1 byte] - Number of pointers in this table
0x12 Unknown [2 bytes]
0x14 index Count [4 bytes] - I'm not sure
Size = 0x18
Straight after this comes [Pointer Count] entries like this
0x0 Index Pointer [4 bytes] - Pointer to a data block
0x4 Table Pointer [4 bytes] - Pointer to another Table of indexes
0x8 Index Count [4 bytes] - Not sure. If non-zero [Table Pointer]
has more indexes?
Size = 0x0C
These [Index Pointer] items point to offsets in the file which are
data items. At present Emails and Folders have been worked on.
Item Header:
0x0 Self [4 bytes] - current offset
0x4 Size [4 bytes] - size of block that follows
0x8 Unknown [2 bytes]
0xA Count [1 byte] - number of items in the block before the data
starts
0xB Unknown [1 byte]
Size = 0x0C
Then comes [Count] number of items:
0x0 type [1 byte] - specifies what the data is
0x1 value [3 bytes] - actual data
The following types have been found for Emails
Type - Value
0x02 -
0x04 - buffer pointer to file offset of email data
0x05 - buffer pointer to asciiz string containing the subject of email
0x06 -
0x07 - buffer pointer to asciiz message id of email
0x08 - buffer pointer to asciiz another string containing the subject of
email
0x09 -
0x0B -
0x0A - buffer pointer to asciiz message ids of parent emails
0x0C -
0x0D - buffer pointer to asciiz Name of sender
0x0E - buffer pointer to asciiz Email address of sender
0x11 -
0x12 -
0x13 - buffer pointer to asciiz Name of recipient
0x14 - buffer pointer to asciiz Email address of recipient
0x1A -
0x1B -
0x1C -
0x80 - Numeric ID (numeric)
0x81 -
0x84 - file offset to email data
0x90 -
0x91 -
The following have been discovered for Folder Items
Type - Value
0x01 -
0x02 - Buffer Pointer to Descriptive name of Folder
0x03 - Buffer Pointer to Filename of Folder
0x05 -
0x06 -
0x80 - Folder's ID (numeric)
0x81 - Folder ID of parent (numeric)
0x86 -
0x87 -
0x8A -
When handling blocks of data (as in Emails) the offset pointer will
point to the following structure:
0x0 Self [4 bytes] - current offset
0x4 Size [4 bytes] - size of block
0x8 Data Size [2 bytes] - size of data inside block
0xA Item Count [1 byte] - number of int size objects before data
0xB Unknown [1 byte]
0xC Next address [4 bytes] - File offset of next data block
Size = 0X10

Wow!!! That looks like fun.
Thanks for the response. I think you've given me enough to think about as to whether I want to continue on with this or to try and find a program that does what I need (or at least close to what I need).
At least now, if I look at one of the files, I should have a better idea of what is going on.
Thanks again!

Hi All,
Has anyone encountered:
An unnamed file was not found
error message box popup in your application before?
It happens when I run the release version of my MFC program outside of MS Visual Studio. When run inside visual studio, both debug and release versions have no errors...
Comments? Inputs?
Thanks.
