Thanks for that. I am going to try the ActiveX adobe.svgctl for the moment, and see if I can figure out how to do the necessary directly from VC++. I'll post again if I get it working! cheers, Neil

What happens if you pass NULL instead of &context to alertSplitter->CreateView()? Also, this call shouldn't be necessary - pMainWnd->UpdateWindow(); Maybe try without it. CSplitterWnd* alertSplitter should maybe be a member variable of the MDIChild class (or somewhere) so it can be deleted, otherwise a memory leak.

Thanks. That works fine. cheers, Neil

Further testing has revealed that the image data column is always corrupted (set to all zeroes) for the first row returned when Open() or Requery() is run against the CRecordset-derived class.. not sure what is different about this first row.. cheers, Neil

Did you find the answer to this question? I have the same problem.

Probably CreateIcon, CreateIconFromResource and CreateIconFromResourceEx will help you. Bytes will come yet again from LoadResource. Also, CreateIconIndirect + ICONINFO could help if you have a bitmap instead. Nuclear launch detected

I think you need to SHGetFileInfo to get information about file and... and also if you dont know about CImageList and its functions search on the codeproject it has a lot of good articles :) WhiteSky

Thanks to both of you for the replies. This seems to be quite tricky. I was looking at using SQLPutData(). There doesn't seem to be a T-SQL statement that does such an insert either.. cheers, Neil

I have worked out how to do this, so I thought I should post the answer here in case anyone is interested: INSERT INTO TEST VALUES(0) /* Turn bit 137 on */ UPDATE TEST SET TEST1 = CONVERT(binary(32), STUFF(TEST1, 137 / 8 + 1, 1, CONVERT(binary(1), SUBSTRING(TEST1, 137 / 8 + 1, 1) | POWER(2, 137 % 8)))) /* Test bit 137 value */ SELECT SUBSTRING(TEST1, 137 / 8 + 1, 1) & POWER(2, 137 % 8) FROM TEST /* Turn bit 137 off */ UPDATE TEST SET TEST1 = CONVERT(binary(32), STUFF(TEST1, 137 / 8 + 1, 1, CONVERT(binary(1), SUBSTRING(TEST1, 137 / 8 + 1, 1) & ~POWER(2, 137 % 8)))) cheers, Neil

Thanks for that. So it is basically a limitation of SQL Server. The first row (a "top level" row) would be inserted with parent_id = NULL, therefore there would be no infinite recursion problem. But no worries, I can workaround it. cheers, Neil

Does this give you what you're after? select *,case when parent_id is not null then parent_id - .5 else id end as OrderByField from x order by OrderByField --EricDV Sig--------- Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them. - Laurence J.

Nope, just didn't realise it was located there. Thanks for your help. cheers, Neil

Thanks again for your comments. Here's some answers to your questions: So you want the output from the perl script written to the log file right? = Yes. Whatever the program - that is launched by CreateProcess() - does, I want all stdout (and stderr) to go the logfile child.out. If the launched program is a batch script, this includes the output from any new processes (such as Perl) that the script may launch. If you run the perl script from the command line does it do what its suppose to? = Well, there is no Perl script here, I am just getting Perl to return its version statement (-v flag). But yes, Perl does correctly return the version statement if I run the batch script manually. If I replace the batch script with a shell script (bash.exe instead of cmd.exe) it works just fine - the output from Perl goes to child.out. It seems that it only doesn't work if the program launched with CreateProcess() is a batch script. What is the perl script doing? Any reason it has to be done from a scipt and not part of your C++ App? = That is not really relevant, because the main C++ program - that runs CreateProcess() - is supposed to allow the user to run ANY program or script he/she likes. I was just testing that it out with a sample batch script, when I came across this weird problem. I can't know in advance what programs the user may wish to run, and I can't ask them to kindly not launch any new processes from a batch script !! :-) For any of the command line commands redirecting the output from the screen to a file is >Path.To.File ie dir >C:\MyLog.log = Yes, but I am not sure how that is relevant here? The output from the "dir" call DOES goes to child.log as it stands. It is just odd that the output from the Perl call does not. I have concluded that the difference is that Perl.exe is a new process, whereas dir is not. There must be something strange with the startup parameters in the CreateProcess() call, but I just can't think what.. I hope this makes sense, and I hope you can work out what I could be doing wrong, because I am totally stumped!! X| cheers, Neil

Stuart Dootson wrote: Sorry - what I should have said was that I didn't like the comparison of the copy constructor to memcpy - it copies each member individually, it doesn't just copy the raw bytes of the object. Which is why I'm quite happy to rely on implicit copy constructors - because 99% of the time, they're implementing what I'd be implementing anyway. The main reason I compare it to memcpy is simply to emphasize that if you have a pointer member variable, only the pointer value will be copied (that is, a new object that the pointer is pointing to will not be created). As a side note, they will only implement what you would do if your data members are simple types. If they are complex types that don't have a copy-constructor/assignment operator defined, chances are it isn't going to do what you would expect (e.g. if you have a custom vector-type class that doesn't have a copy-constructor). Stuart Dootson wrote: I take your point about having copy constructors to step through @ debug time - it's just not something I find myself doing. After finding myself trying to debug implicit functions several times, I got in the habit of making sure they were explicit. It only takes one time of spending a week trying to figure out why your code doesn't work (when it should) before you want to make sure you don't run into the problem again.

No, I think you are right. At the time I was using code from OpenSSL, and I think that causes some strange things to happen. I changed my algorithm, and now it is fully working. So I don't think there really is a bug with the MS software, you just have to be careful with these functions, and call them at the right times etc. cheers, Neil
