• Software Development for Windows Vista Cannot build assembly with COM interop, VS2005 + Vista beta 2

  When I build an assembly using msbuild that has COM Interop, msbuild fails in the UnManagedRegistration target. c:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets(2720,9): error MSB3216: Cannot register assembly <assemble name> - access denied. Access to the registry key 'HKEY_CLASSES_ROOT\<com class name>' is denied. I am running msbuild using an user with Administrator permissions. The OS is still set to request the user for elevated permissions. u need actually to start a cmd in Vista using 'run as' administrator, before this will happen.

• .NET Development insert row into table with autoincrement primary key

  I have a table in a dataset with a column being autoincrement and primary key. My question is: How do i insert rows into this table been using DataRow Row = Table.NewRow(); and then setting fields and Table.Rows.Add(Row); But if i don't set a value for the id column it won't let me insert the row. Shouldn't the id column be updated automatically One thing you will want to do is set the autoincrement property to -1. this will insure a unique Key when your update is performed on the database. For example If I do a filtered read and it returns the IDs 1, 2, and 3. The data set will auto increment 4. When I do this write to the database if there is an ID of 4 you will get an exception. The big question is why ...Show All

• .NET Development XML, Excel, VB.NET and some guidance ...

  Hello, Is the a way i can acomplish these tasks : a. Within a windows form, open an xml document ( i use spreadsheet 10.0 com object ) from a specified location , b. Save it, also as xml, but somehow index it, so when i open it ( just like point {a} ) not to use the absolut path of the file ( C:\ Documents \ ... ) but rather this index. I chose this approach because the environment i work in is not organised, files are often moved, and so on. Also, for this i was thinking to create a service based on the fileSystemWatcher events ( changed, moved, etc ). I observed that class is able to determine, in case of a moved file, the new location. Please, if someone could help me, i would really appreciate it ! P.S. I promise to r ...Show All

• Visual C# Best way of returning an image based on a string

  Part real-world issue, part idle curiosity, this. I'm adding a static class to my project which will provide little images from the resources based on a string value -- specifically, a Type name from the various business objects -- to be displayed on tabs, list-views, that sort of thing. Anyway, it's currently implemented via a big ol' switch statement, thus: switch (typeName) {     case "CompanyDataSet.Contact":     case "PersonDataSet.Contact":     case "CompanyDataSet.ContactDataTable":     case "PersonDataSet.ContactDataTable":         if (imageState == ImageState.Disabled)         {  &nbs ...Show All

• .NET Development receive in different thread Cause troubles

  hi, i wrote a class to send and receive data from a server, i intiate the receive method in a separated thread , when packet arrive i raise event, in the other class i consume it, so i have 2 questions 1. some times the server send packets too fast, and that cause trouble in reading data for the consumer class. some one suggested to use a delegate , for that i raise the event through a delegate but still cuase troubles, so what i suppose to do for that 2. i'm using the lock(this) keyword with the consumer method and thread.sleep() in the receiver now but i'm afraid this might cause losing some packets i thought to use delegate like winForm controls to make it thread safe by invoke it, but i don't know how to write this method ...Show All

• Windows Forms How to get or read the last letter from a text box? - Vb.net or VS 2005

  Hi I have a TextBox in a windows form to enter 10 digit number followed by 2 letters. (Ex: 304528929 GH ) I have a code (got from my other thread) to calculate the total of the above digits(3+0+4+....) and dividing the total by someother value to get the reminder . IT ALL WORKS FINE Also I have list of alphabets with equivalant value like below A = 3 B = 7 C = 1 H = 12 ........ ........ Z = 22 My question: If the reminder matches one of the above list , for example reminder from the above calculation is 12. So it matches with H = 12 . So If H is the last letter of 304528929 GH , then the user input is right. In Short : HOW DO I GET THE LAST LETTER (ex. 'H' in the above case) From the textbox and check w ...Show All

• Visual Studio Tools for Office Range.InsertBreak generates exception

  Hi All, I'm inserting a break in a Word 2003 document which has some XML tags. It works fine for most of the documents but errors out for some documents where the XML tags are placed haphazardly i.e. not in an orderly manner.

• Visual C# Generic Multi-Dimensional Arrays Comparison

        Hi,     I need to compare multi-dimensional arrays in a function which takes 2 multi-dim arrays which can be any type(int, double, bool...etc). Comparison is done by Object.Equals() of each value in each index of the arrays. As a result, Generic and  Multi-Dimensional is what I need to combine. Any idea I compare 1 Dimensional-arrays with the below code of mine: public static bool AreArraysEqualByVal<T>( IList <T> src, IList <T> dest) { if (src == null || dest == null ) throw new ArgumentNullException ( "source or destination array is null." ); if (src.Count != dest.Count) { Debug .WriteLine( "Array lengths were not equal." ...Show All
