• Manoj Verma ODBC TableAdapter Updating

  Hi, I have searched high and low to find an example to solve my problem. I use ODBC to connect to MySQL database, or any other for that matter, the application has no real call for Datasets/adapters till now so I have not used them. I now need to load an image into a blob field so using Commands and readers do not hack it. Try as I might, and I have tried, I can not see how using dataset/tableadapters etc I can add a record to a table let alone stream into a blob field the image. Any help would be welcome.

• Jerod Moemeka Solution problems when developing on multiple machines

  hi, I have an ASP / C# .NET2.0 web project that I manually check into & out of VSS on to a primary development system running Visual Studio 2005 Pro. It all works fine. But how can I check that solution out to a different machine The .sln file has hard-coded path and GUID info, so tightly bound to its host machine. No way it belongs on any other machine. There doesn't seem to be a 'create project from source' for ASP projects...am I stuck with having to create a new ASP web project & copy my sources over thanks for any help & have a nice holoday weekend:) See these references about .NET 1.x and team development to see if they apply to .NET 2.0: http://www.mztools.com/resources_net_developers.h ...Show All

• K. Ravinder Reddy Question about reading in attributes

  Hi all, I have a question concerning the use of attributes. I have a base class with attributes and a class which inherits from the base class with additional attributes. When I read in the attributes of the inherited class through reflection, the attributes of the inherited class are always read first while the attributes of the base class are read last. Since the order is important to me, is there a way to force the program to read the attribute in the base class first I hope I stated my question clearly. Thanks ahead of any help or recommendation. David Thank you Michael for the recommendation. I think I would have to use the algorithm mentioned to manually enforce the order. I was hoping ther ...Show All

• xavier.oudin Does format file for bulk insert allow mix of native and character format?

  I have a module which require me to import big amount of data. I believe that the native format data files with format files will be the most efficient way of implementation. The problem arises when I need to import datetime and decimal(numeric) fields because I don't know their internal format or how to convert to this format from strings or CLR datatypes. So if the answer to above question is positive I can partially resolve the problem, if negative I will have to use the character format. Unless you can educate me on the convertion to the SQL server internal formats of datetimes and decimals from the CLR types. I am trying to programmatically produce a BCP like exported files of native format(it means without type conve ...Show All

• averge joe Why doesn't my C# form show the contents of the database?

  Hi All, I'm using VC2005 in C# trying to create a windows app that displays the contents of the tutorial northwind.mdb. I've followed the tutorials and created a dataset and dragged the customers column onto the form and it all compiles and runs fine but none of the elements on the form get filled in with the contents of the database, also the BindingNavigator has no items to navigate. What am I doing wrong and how do you make the app automatically load in the northwind database and display the contents on the form Actually I just talked to the Jet PM and they are looking at somehow providing a 64-bit version of Jet provider (they are deciding if they are going to do this or not at this point at least).

• Pirooz Javan (Old) What did I do wrong (Getschema method in SQLServerCE)?

  I have a problem with the Getschema method in the SQLServerCe namespace - I am fairly new in C# so I may have overlooked something. My problem is that I have only the C# Express edition (I don't have the mobile projects) so I am "forced" to make my own viewer for my SQL Compact databases (.sdf) as I can't use SQL server Management Studio Express for these files. However, when I use the Getschema() method in the corresponding namespace it seems to not work. This is the code I used: string connstring = @"Data Source=c:\!studiec#\betatest.sdf" ; SqlCeConnection myconn = new SqlCeConnection (@connstring); myconn.Open(); DataTable mytable = myconn.GetSchema(); I get the error "Spe ...Show All

• Giugio Creating a new website in Visual Studio 2005.

  When I create a new website in Visual Studio 2005, VS2005 always puts my solution file in C:\Documents and Settings\my_login_name\My Documents\Visual Studio 2005\Projects\my_project_name. Is there a way to customize this behavior and to have it ask me where I want my solution file is instead of always putting it in the default location Then the rest of my file are always put in C:\inetpub\wwwroot\my_project_name. This is again, not the location where I want to put the files. I want the solution file and the rest of the files in one location of my choice arbitrarily in my C: drive, then have a virtual directory in IIS pointing to the location. Are there any ways to change these behaviors It is irritating. ...Show All

• ronwest99 WebService - Passing page as a byref parameter

  As far as I could tell this is the best forum...apologies if it isn't. It is our task to dynamically change label and link texts on web pages based on login info. We must do this for several hundred pages every time they load. It seems a web service would be the most centralized method of accomplishing this, unless there's a tweak for global.aspx. The method I would like to use is to pass the page into the service by reference, change the texts inside the service, then return the page. My question is, how can I pass an aspx page by reference into a web service (or accomplish anything similar) If I need to elaborate more please let me know. Sadly enough I am too new to adequately answer that qu ...Show All
