• Windows Forms BindingSource problem when AddNew() get Called and when a control lose the focus

  Hi everybody, I somehow developed a generic form, that allows to speed the development of forms, because the form have the insert, update, delete, retrieve, etc, all ready implemented. I inherited the winforms controls to work whit this form, so I can extract the info and create the statements to be executed in the DataBase. I Have a control inherited form the TextBox, I added a new property that works like a keyValue for the text showed in the Text property, it's like I have a Table in the dataBase, and one column in the table, is a key to other table, so, I bring the table to memory, in a DataTable, but I can't show the key to the user, the user must see the text related to the key, so I added the property to my inherited control ...Show All

Can anyone with experience point me to the right direction with this package I also looked at the admininstall.html file but It doesn't help me much. The file tells me to create .mst but how can I deploy the .mst without creating or having the .msi Thanks in advance. ...Show All

• .NET Development C# + Access Database Problem

  Here's my issue. I have a program in C# that creates and track help desk PC tickets.It saves and loads data from an Access database that I created. Everything works great, but I have recently decided that I need to add some more things like the ability to input the date that the customer was called on the form as well. So what I am trying to do is create another couple of colums in the already exsiting database using Access, then create textboxes on the form and have them link to the new colums in the database. The best I have got so far is to create a new database, but I don't want to have to retool the entire form all over again if I can help it. So, my question is, simply put, is there any way to update a Access database already in use ...Show All

• Visual C++ Read access violation when buffer bigger than 2048

  Hello, I'm an old mainframe assembler programmer and I'm trying to teach myself C++. I've bungled through writing a program to copy a file (just to get familiar with I/O. The program works fine when variable BuffSiz is 2048 or smaller. If it's bigger, I can't even start debugging. The error is: Unhandled exception at 0x004012af in Compression.exe: 0xC0000005: Access violation reading location 0x00371000. I am using VS2005 on XP SP2 with the latest SDK. This is a Win32 Console App. This is my first program so please ignore (and advise of) the many shortcomings. Also - how do I get the code to post here as it is formatted.

• Software Development for Windows Vista Momento SideShow

  The Windows SideShow driver (BETA) for the i-mate Digital Photo Frame (Momento) was launched today.  Owners of Momento frames can now receive glance SideShow content over their wireless network from their Windows Vista PC. http://www.momentolive.com Hurrah! Thanks, I had tried the driver from the website, but it is that one which is unrecognised by the hardware installation wizard. Also, Windows Update has never offered a driver.

• Game Technologies: DirectX, XNA, XACT, etc. Content Pipeline Interfaces

  Hi, we stand in front of a real big problem, becaus we lose really a lot of time waiting for the new content pipeline. Because we develope a commercial project time means money. I can understand if you cant release the content pipeline before the holidays, but we also must continue our development. Is it possible to release a next beta, with full documentation of the Content-Pipeline-Interface, so that we can continue our development I want to know, how i can Load Sound-Files, Models, Textures and all the other stuff with the content pipeline. I have seen, that the complete loader is available. Perhaps you can support us with some example XNB-Files, which we can load. Bummer! I think XNA becomes really goo ...Show All

• Visual Studio 2008 (Pre-release) More control over callback DispatchRuntime in Duplex contracts

  Hi, I have two services that communicate through the exchange of one-way messages. There's not really a "client" or a "server", because either one of the services can start a conversation with the other one, so I will use "serviceA" and "serviceB" from here on. I used the WCF duplex binding in order for the two services to communicate with each other. I have written a custom ServiceHostBase that does some extra stuff for the project I'm working on and I would like to use the same ServiceHost implementation on both sides (i.e. "serviceA" and "serviceB") because the extra stuff is beneficial to both services. What I would like to do now is start my custom ServiceHost on the "se ...Show All

• Visual Studio Super slow installation for VS2005 SP1 beta

  Well, it’s not something new, there are people at Microsoft that work hard to make our life easier, like the Microsoft Windows Vista installer for example, an entire OS in 20 min; and there are some less experienced developers (my assumption only) who are given for some reason the task of creating the VS2005 SP1 installer. Whoever wrote that thing, he, she or they, can say whatever they want, but to take 2 hours to get the SP1 beta installed is just damn stupid, here are 2 hours by a million people in the world, a total of 2 million hours lost, thanks to a group of developers at Microsoft, maybe they could have spend 100 more hours to learn math, or to profile the installer, and could have saved the world a million hours ...Show All

• Visual Basic How to install an assembly in GAC
