Hello,

the question is related to automation with excel
I have used chart types and to draw stock volume option
xlStockVOHLC = 91 . The data is arranged properly in excel sheet but how to select data for the chart in columns

i m using the following for data range

_Chart newChart;
Range oRang;
oRang = newSheet.GetUsedRange()
newChart.SetSourceData(oRang,COleVariant((short)1));

And is it working? Have you tried the sheet's GetRange() method?

Hi,
I have a question there are tools that can identify backdoors in a code by analising binaries of application i.e by doing re-engineering. Can anybody tell me how this works and is there any tool available for this.

Thanks

Why would you need to do this, are you trying to break into a bank?

No...I just want to know that is there any tool which does binary (.exe in release mode)inspection so that backdoors can be identified. If yes, whether it is possible with release version of exe or only with debug. Also would like to know are they using assembly code analysis of binary to come to conclusion?

It's always possible. Sometimes it's a little harder than otherwise, but it can not be impossible (since that would mean that you can not see any code, and then how would the CPU know what to do with your program?)

I think Google is the place to look. However, I am not sure that any such tool could identify what you term "backdoors".

You may use the dumpbin tool [^], looking for 'backdoor' or 'please hack here' or 'virus place holder' sections.

In general it would be hard to imagine how such a tool would work. The kind of thing you're asking for requires intelligence, which is something computers don't do well; they do dumb but fast. The normal way one would go about doing such a thing would to be use various tools, such as disassemblers, to take out some of the grunt work and help you visualise what's going on, but the user (you in this case) would do the "real" work.

Calling external exe in separate shell?

Hi there,

I got trouble with calling externals. Maybe somebody can help me.

I used to call external programs (exe-files) with the system() call. Now I want to start an external program in a seperate shell (and as a separate process). Can anybody tell me how to do that?

Thanks a lot.

call a batch file. In it can you create an own environment.

Use one of the exec()[^] calls. They create a separate process and also allow some communication with the parent.

What exactly do you mean; columns are fixed alphabetic identifiers starting at 'A'?

Are you referring to the range's GetName() method?

File size and File size on disk

I use file-manager to view property of my exe file, file-manager displays:

File size:	3,401,216 bytes
File size on disk:	3,403,776 bytes

You see, sizes are different.

What do they exactly stand for?
What C functions are related or used for obtaining the sizes?

"File size" is from FindFirstFile(...) function - just tested.
But which function gets "Size on disk"?

They mean exactly as labeled. The size of the file is 3,401,216 bytes but when it is stored on the disk it takes 3,403,776 bytes.

This is because you can allocate space from HDD only in blocks, for windows it is 4KB. So even if you create an empty text file it will still take 4KB on HDD.

Fake info.

You try a empty txt file to see its "size on disk", which is 0.
