• WOW64: get x64 %CommonProgramFiles% from 32 bit process

  - by peterchen

  Queries I tried: ExpandEnvironmentStrings("%COMMONPROGRAMFILES%"), GetSpecialPath(CSIDL_PROGRAM_FILES_COMMON). All resolve to (typically) c:\\Program Files (x86)\\Common Files from my 32 bit app. I need to check a file version installed (typically) under c:\\Program Files\\Common Files of a 643 bit application.

• Determine 32/64 bit architecture in assembly

  - by dboarman-FissureStudios

  I was reading over this question and wondered if the accepted answer might also be a way to determine the architecture. For instance, in asm could I push a WORD onto the stack and then check SP. Compare the new SP to the old SP: Diff of 4 means 32 bit Diff of 8 means 64 bit Am I correct in this thinking?

• Does the VB6 IDE run on Windows 7 64-bit

  - by jasonk

  We're approaching a point of replacing several of our developer PCs and would like to move up to 64-Bit to maximize the hardware/life of the PCs but we also need to support several legacy VB6 applications. That said, does the VB6 IDE run on Windows 7 64-bit? Microsoft says it's not supported, but that doesn't necessarily mean it doesn't work. Does it work? Are there any pitfalls/workarounds needed to get it running?

• Binary to Date (C#) 64 Bit Format

  - by Veskechky

  We have a binary file from which we have identified the following dates (as Int64). We now the following facts about the Date/Time format; The 64 bit Date has a resolution to the microsecond The 64 bit Date has a range of 4095 years The Int64 9053167636875050944 (0x7DA34FFFFFFFFFC0) = 9th March 2010 The Int64 9053176432968073152 (0x7DA357FFFFFFFFC0) = 10th March 2010 The Int64 9053185229061095360 (0x7DA35FFFFFFFFFC0) = 11th March 2010 The Int64 9053194025154117568 (0x7DA367FFFFFFFFC0) = 12th March 2010 Any help on figuring out a way to convert this to a valid C# Date/Time is appreciated.

• Show bit Column as a checkbox column in unbound Datagridview

  - by Name.IsNullOrEmpty

  Dim Comp = From C In db.Table1 _ Select C.Completed, C.Taken, C.Namne Datagridview1.DataSource = Comp Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values. I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound. how can i change this in code at runtime

• Cleanest way to build an SQL string in Java

  - by Vidar

  I want to build an SQL string to do database manipulation (updates, deletes, inserts, selects, that sort of thing) - instead of the awful string concat method using millions of "+"'s and quotes which is unreadable at best - there must be a better way. I did think of using MessageFormat - but its supposed to be used for user messages, although I think it would do a reasonable job - but I guess there should be something more aligned to SQL type operations in the java sql libraries. Would Groovy be any good? Any help much appreciated.

• How to get LSB bit in MIPS?

  - by israkir

  Is there a short way to check/get for least significant bit in a 32-bit integer, in MIPS? It is obviously set for the odd numbers and an algorithm which checks for the whole number is odd or even can decide for this. But I just wonder is there a better way to do this...

• Diagnosing problem with running ASP.NET app as 64-bit

  - by user54064

  I need to run an ASP.NET app as 64-bit. The app is quite large and has MANY assemblies to load. When I run it I am getting "is not a valid Win32 application" error in the web page as soon as I go to the first page. That page is a very simple "Hello World" page. However, it must be having problem with loading assemblies as 64-bit. How can I figure out which one(s) are the problem?

• How to invert alternate bits of a number

  - by Cupidvogel

  The problem is how to invert alternate bits of a number, starting from the LSB. Currently what I am doing is first doing a count = -1 while n: n >>= 1 count += 1 to first find the position of the leftmost set bit, then running a loop to invert every alternate bit: i = 0 while i <= count: num ^= 1<<i i += 2 Is there a quick hack solution instead of this rather boring loop solution? Of course, the solution can't make any asumption about the size of the integer.

• 64 bit tools like BoundsChecker & Purify

  - by titanae

  For many years I have used two great tools BoundsChecker & Purify, but the developers of these applications have let me down, they no longer put effort into maintaining them or developing them. We have corporate accounts with both companies, and they both tell me that they have no intention of producing versions to support 64 bit applications. Can anyone recommend either open source or commercial alternatives that support 64 bit native C++/MFC applications?
