• Visual C++ Confused about function prototype signitures from C++/CLI to C#

  Hi, I'm trying to write a C++/CLI wrapper class that wraps up a bunch of native C/C++ legacy functions in a new class that any .NET language can use. I've come across some confusing problems with regards to function signatures. For example, say I have a function written in C++/CLI like public ref class LegacyCode { public: static void function1(int ^%year, int ^%month) { // do stuff like calling the equivalent legacy function } } How do I call this function from something like C# public class CSharpDriver { public DoIt() { int myYear; int myMonth; // Call legacy function through wrapper to get the current year and month function1(out myYear, out myMonth); } } ...Show All

• Windows Forms launch condition to check for available disk space

  I am trying to add a launch condition to check for available disk space before uses can install my application. I tried to use the PrimaryVolumeSpaceAvailable Property but it looks like it has no value at launch. I also wanted to check the processor speen so I used a registry search to HARDWARE\DESCRIPTION\SYSTEM\CentralProcessor\0 to get key '~Mhz' , its returning the correct value but with a #, I wanted it to return an integer so I can use it to set my cpu speed launch condition. Please help The reason I need to check for disk space is sometimes the application ships with a sql databse which will need to be restored , so I want to make sure that the space for the database is catered for before ...Show All

• Visual Studio 2008 (Pre-release) ScaleTransform issues

  I've created this sample in XamlPad to try to workaround some issues I'm facing when using ScaleTransform. The problems I've found are: 1. Because I'm using RenderTransform, the border has some issues with items which are in front in terms of ZIndex. Is there any way I can solve this in XAML - I know I can try changing the ZIndex property for the items in the listbox when they are selected, but I'm trying to do everything from XAML. - I don't want to use LayoutTransform (which would solve this issue) because I don't want other items in the listbox to move around when the Selected item changes. 2. Moving around with the keyboard inside the ListBox does not seem to work correctly. Is there something wrong with my code ...Show All

• Windows Search Technologies WDS 3.0 RTW - Have to reinstall filters

  I found that after the install of WDS 3.0 RTW, I had to reinstall my pdf and other filters to get WDS to see them. Interesting - thanks for the feedback. It sounds like the install failed to register the existing IFilters with WDS. Which IFilters did you have to reinstall It may be possible to make sure this doesn't happen in future versions.

• Windows Forms How do I package a Hotfix in my installer?

  I have a hotfix from Microsoft that is required for my application to work properly. How do I add it to the installer package I am using VS 2005. The hotfix in question is: http://support.microsoft.com/default.aspx/kb/913177/ Jonathan Allen Another approach would be to create a bootstrapper package and install it using the bootstrapper.

• Visual C# string to hash

  TextBox1.Text.GetHashCode(); I get the hash code but I can't convert it back to string. How can I do this you cannot get value from hash. Defnition by wikipedia: A hash function (or hash algorithm ) is a way of creating a small digital "fingerprint" from any kind of data. The function chops and mixes (i.e., substitutes or transposes) the data to create the fingerprint, often called a hash value . The hash value is commonly represented as a short string of random-looking letters and numbers ( Binary data written in hexadecimal notation). A good hash function is one that yields few hash collisions in expected input domains. In hash tables and data processing , collisions inhibit the distinguishing ...Show All

• SQL Server Delete one of the duplicated row

  I have many data in a table in which some rows are duplicated.  How can I, for all duplicated rows, delete the extra rows and leave only one   You may assume checking one column is enough to tell if a row is duplicated. Thanks Please look at my reply in the thread below for some solutions. You can do this with a single DELETE statement and batch it using SET ROWCOUNT or TOP clause if you have large number of rows to delete. And if you don't have any primary key or unique key on the table then you can use a cursor based approach. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=666011&SiteID=1&PageID=1 ...Show All

• Visual Studio Express Editions using VBE across a LAN
