• OpenMsgStore fails: MAPI_E_NO_SUPPORT or E_ACCESSDENIED

  - by KellyLynch

  I have to support an old C++ program (I am not its author) that uses Extended MAPI to scan mail folders from Outlook 2007. Suddenly the software began meeting problems on one customer's computer by the following scenario: call of OpenMsgStore fails for some folders with code 0x80040102 (MAPI_E_NO_SUPPORT ). for other folders it fails with code 0x80070005 (E_ACCESSDENIED). But other folders opened by OpenMsgStore OK. What can be reason of the problem?

  - by mpcabd

  I'm implementing a compiler in my Compilers class, I'm using Qt & C++. After I have generated the machine code from the source code, I'm executing the virtual machine that will execute the call. I'm facing a problem here, I'm using readyRead() signal to get output from the virtual machine, but how can I know that the virtual machine wants to read data from the user? I wanna show the user an input dialog each time the machine asks for input.

• Difference between macros and functions in C in relation to instruction memory and speed

  - by DAHANS

  To my understanding the difference between a macro and a function is, that a macro-call will be replaced by the instruction in the definition, and a function does the whole push, branch and pop -thing. Is this right, or have I understand something wrong? Additionally, if this is right, it would mean, that macros would take more space, but would be faster (because of the lack of the push,branch and pop instructions.), wouldn't it?

• Haskell -> After parsing how to work with strings

  - by bito08

  Hello after doing the parsing with a script in Haskell I got a file with the 'appearance' of lists of strings. However when I call the file content with the function getContents or hGetContents, ie, reading the contents I get something like: String with lines (schematically what I want is: "[" aaa "," bbb "" ccc "]" - ["aaa", "bbb" "ccc"]). I have tried with the read function but without results. I need to work with these lists of strings to concatenating them all in a single list. Thanks.

• How can I tell the number of replacements in a formatter string?

  - by sdanna

  Given the following method: (real method has a few more parameters, but the important ones are below...) public string DoSomething(string formatter, params string[] values) { // Do something eventually involving a call to String.Format(formatter, values); } Is there a way to tell if my values array has enough objects in it to cover the formatter, so that I can throw an exception if there aren't (short of doing the string.Format; that isn't an option until the end due to some lambda conversions)?

• Why is ColdFusion adding whitespace when I put the output of a function in a string?

  - by Kip

  If I do something like this in ColdFusion: <cfoutput>foo="#foo()#"</cfoutput> The resulting HTML has a space in front of it: foo=" BAR" However, if it is not a function call it works fine, i.e.: <cfset fooOut=foo() /> <cfoutput>foo="#fooOut#"</cfoutput> Gives this output: foo="BAR" Where is this extra space coming from and is there anything I can do about it?

• Git push from post-receive

  - by meka

  I have two servers, let's call them first and second. First one is where the real development is done, and second one should be the replica. What I would like to do is put "git push" in post-receive, but there is one problem. Post-receive is executed as the user doing git push to first server, so I can't chmod 600 ssh key with no pass. What is the best practice for this? Thanx!

• How to place multiple formats on the clipboard?

  - by trudger

  For example, what Wordpad did when I press "Ctrl+C"? It places many different format to clipboard. So Notepad can get the text without any color or font...etc, and you still can keep the original format when you paste in another Wordpad window. The MSDN said I should call SetClipboardData multiple times. But it doesn't work at all.
