• Ian Sugar Can't Update, Repair, or Uninstall Microsoft .NET Framework 2.0.

  Hello. I have recently found a security patch for my Microsoft .NET Framework, V 2.0. I needed the framework installed for my ATI Driver update to work. However, Every time I tried to install the patch, it failed. I tried repairing the framework, but that didn't work. Neither did uninstalling it. Uninstalling and Repairing yeilded the following message: "The following error occured during setup: Patch Package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package." I downloaded and installed the framework from ATI's site. My system is a Windows XP, and I would like some help... Please... Thanks for any ...Show All

• marcusadolfsson Time scheduling datatype: Schedule, Duration

  Hi, one little question here, i can't find it thru the search, might not be using the correct search keys. What datatype should I use to indicate time I mean I want to store 2:00AM, or 5:00PM, just the time, without the date. So it is something like a schedule, a schedule that will runs for multiple days. Secondly, how should I indicate duration Duration like, 30 minutes, 2 hours Since, the unit of measurement is different, be it hour, or minutes; should I change it into the smallest feasible unit of measurement, or should I create a new data structure to store it Is there any ready made data structure in .net Thanks Eugene thanks Lowendahl.. what do you mean by there is now a special Tim ...Show All

• tony noriega Reflecting on Properties

  How can one determine the common or garden access modifiers of a property (i.e. public, private virtual, override etc) - the PropertyInfo class does not have an Attributes property nor any IsPublic, IsFamily etc properties. The get & set methods have such properties but its not clear to me how one determines which one inherited its modifiers from the property and which one has the accessor specified modifiers. Nor can I see how one can easily determine that a property uses the override attribute to "hide" one of the same name in it base.

• Honey! httpwebresponse.getresponsestream() not working :(

  I have a problem using HttpWebRequest/Response, GetResponseStream() will never return a readable response, even though the complete response came through to the client side.

• minority80 App.Config - Enterprise Library - Security Issues

  Hi guys, I am just trying educate myself on the usage of the Cryptography Application Block from the Enterprise Library. When you select a symmetric algorithm and then define a key file using the Enterprise Library EXE, it modifies the contents of your application's app.Config file. When examining the app.Config file, I can tell the name of the symmetric algorithm used and the location of the keyfile. Forgive my noob understanding but doesnt this pose as a security risk Since the location and the name of the symmetric algorithm are presented in clear text How does one go about protecting this type of sensitive information within the app.config file. Is there an enterprise library method that I could use to encrypt this section of the a ...Show All

• JIM.H. Creating class to create bitmap of forms graphics object

  I often need to capture a forms drawing surface and write it to a file. Typically I'd create the bitmap then save that and draw it to the forms graphic object but I'd like to do this more generally. Here is some code to create a class to do that but I cannot get to work. The gaphics from g does not transfer to ng and therefore the saved file is blank. class ImageCreator { public void CreateStill(System.IntPtr WinHandle, int w, int h) { Graphics g = Graphics.FromHwnd(WinHandle); Bitmap bmp = new Bitmap(w, h); Graphics ng = Graphics.FromImage(bmp); ng = g; bmp.Save(Application.StartupPath + "\\img.bmp"); } } I'd call it like this: ImageCreator ic = new ImageCreator(); ic.CreateStill(this.handle, this.ClientSize.Width, this.ClientSi ...Show All

• WinDeveloper Optimizing array use

  Currently: User data is being pulled from a database. The returned recordset is looped through and saved into a variant array (using classic asp here) . For every user, there is a ReDim Preserve (5, NumUsers) call. As the data is being put into the array, there is some business logic being applied that SQL is not suitable for. The array is then sorted based on values generated by the business logic and displayed in a web page. The problem: Although inefficient, this has worked quickly (under 3 seconds for a page load) in the past because Customers have had very few users each. We are now getting a customer with a very large user base and even a fraction of their users will be enough to slow a page load down to a minute or two. As ...Show All

• coconut113651 How can I synchronize two MS Access tables?

  Hello, I have 2 MS Access databases, In each database I have a table called catlog. What I want to do is to check the catlog table in database (B) and pass over each row to see if it (the row) exists on table (A).

• AlucardHellSing Specifying framework version with COM interop

  We are having problems with COM interop called from a Classic ASP Page loading the wrong version of th framework. If I load an assembly written in 1.1 on a computer which has multiple versions of the framework 1.1 & 2.0 and it is called from another assembly everything is OK and it uses the correct version. However, t here is documented behavior with COM interop where it ignores the registered version of the framework in an assembly. I f the same assembly is loaded through COM interop it loads and runs in the 2.0 framework. Seems this behavior is noted and documented ( http://west-wind.com/weblog/posts/1319.aspx ) and even some potential solutions - Here and here but these only seem to work for apps that don't get register ...Show All

• Subhas Publisher Policy to patch another Publisher Policy

  Is it OK to provide two publisher policy files for a single version of an assembly e.g.: PubPolicy 1.0.0.0 redirect to 1.0.0.1 PubPolicy 1.0.0.0 redirect to 1.0.0.2 How will the CLR loader respond to this Will it pick the latest version It would be nice if it worked this way since it would allow us to provide roll-up patches. I guess the other approach is to provide a redirect for the previous publisher policy file e.g.: PubPolicy 1.0.0.0 redirect to 1.0.0.1 PubPolicy 1.0.0.1 redirect to 1.0.0.2 This isn't quite as nice because it requires the 1.0.0.1 patch to be installed before the 1.0.0.2 patch can be installed.
