• Visual Studio nmake: control characters

  Consider the following rule: foo\rbar: @echo $@ Expected output is the target name, i.e. "foo\rbar". On one machine, though, the \r is interpreted as control character (carriage return), producing the output "bar" only (writing "foo", restarting at beginning of line, overwriting with "bar"). Windows XP Pro nmake 8.00.50727.42 A different machine also running XP Pro and the same nmake version shows the correct behaviour. Any ideas which settings to tweak Escaping by double backslashes works, but (as you might have guessed ) the above example is very simplified. Unfortunately, escaping the \r in the real environment isn't a viable option because we mu ...Show All

• SQL Server Access to the property values for my expressions

  I may be looking too hard for this but I can't find a way around it. I have an Expression and in that expression, I want to access a property on the same object (it would be great to get the properties of other objects as well). Example: I have a flat file connection where I defined the name of the flat file in my ConnectionString. I also have a variable that I have it linked to my dtsConfig which points to the proper folder name at run time. How can I create an expression similar to this: @[User::strFolder] + @[Connectionstring] where @[User::strFolder] is my variable and points to the correct folder for the given server the package is running on and @[Conenctionstring] is my made up name to access the VALUE of the Connecti ...Show All

• Visual Basic Unexpected effect when closing a form

  Hello all, I am developing a project that has several forms all globally visible: Public hndlToForm1 As frmForm1 Public hndlToForm2 As frmForm2 and so on. When switching from Form 1 to Form 2 for example, I want only form 2 to be open, so I use the following code: hndlToForm2 = New frmForm2 hndlToForm2.Show() hndlToForm1.Close() At this point my impression is hndlToForm2 points to an instance of Form 2 and, thanks to hndlToForm1.Close(), hndlToForm1 is NOTHING; however as I am debugging my code, that is not the case. Despite using hndlToForm1.Close(), hndlToForm1 is not NOTHING, the debugger shows. My questions follow: 1. Does this mean that hndlToForm1.Close() has not freed up the memory used by hndlT ...Show All

• Smart Device Development Memory requirements for Compact Framework v2.0 and SQL Server Mobile

  Hi, I'm looking for some information on the memory requirements of installing the compact framework v2.0 and SQL Server Mobile onto a mobile device. What would be the minimum RAM/ROM requirements for the mobile device for installing both Thanks NETCF V2 is about 6 MB uncompressed/2 MB compressed. SQL Mobile core is about 1.5 MB uncompressed/.6 MB compressed. SQL Mobile replication support is about .7 MB uncompressed/.3 MB compressed. You need that amount of storage in order to install - PPC 03 compresses storage, WM 5.0 does not. Plus you need storage for your database, up to 4GB. RAM needed in order to run depends greatly on your application, could be as little as 2MB. Store your data in memory in DataSet or ...Show All

• Visual C# pdf file release version of C# 2005

  In 2005 C# , visual studio is generation pdb files for release version What is the purpose of pdb file for production deployment and I deploy application without pdb does it have any effect Thanks You can deploy the application without pdb files, no problem, especially that they can be quite large. They are useful in case when an exception occurs because you can see the line numbers in the stack trace, not only the function names. Also sometimes you might need to debug the release version and without pdbs it's not going to work properly. ...Show All

• Visual Studio Tools for Office Why does the ContextSwitchDeadlock happens?

  I got following error in a very basic VSTO Excel Workbook project. My method responds to a hyperlink, sets some integer values in a 10x10 cells array; and then user rng.Find() to find a specific string. However, the last part is when the while loop continues trying to get the next string with rng.FindNext(foundRange). The strings are found, but then Excel does not return from it (it takes all my CPU time); and finally, I got this error. ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x159bc0 to COM context 0x1598e0 for 60 seconds.
