• Visual Basic Formatting TextBox bound to a database column

  I am facing two problems, pertaining to formatting the textboxes in my VB.NET project with SQL Server. First, I have a TextBox bound to 'Smallmoney' column, which displays the number upto 4 digits after decimal. I want to make it display just to 2 places after decimal. Second, another TextBox bound to 'Smalldatetime' column, does not let input date in "dd-mm-yy" format. I want to get it done programatically, without manual modifications in the "Regional Options". I think, the second problem can be solved using the Culture object, but I don't know how to do it. Is there anybody who can help a novice, please! One novice to another, do this.

• Architecture Typed Dataset or Custom Classes

  Hey friends, I am a VB developer, soon I am going to start a new project. It will be a client application, I will use a SQL server database. I am used to use custom classes, I create my onw variables properties, events and methods. I am aware of the Typed Data Set and thinking about using it on my new project. The problem is that  I have never used it,  I do not know the minuses and plusses of the Typed dataset. Now, my boss and me on the desicion phase, we want to implement the most efficient and easy maintainable one. If you ask me , I'm quite happy with custom classes :)) My opinion is that the custom class is better for performance purposses, because I  create properties and meth ...Show All

• Visual Basic Advanced data bindings and DBNull

  My project reads dates back from SQL Server and displayes then using a Details view. In some instances, two of the dates displayed are meaningless data, they only apply if another value is set. Under DataBindings - Advanced, I notice you can set a NullValue to display in the event of a DBNull being returned. Well, the fields are Null (at least according to the Show Data function in Database Explorer) but regardless of what I put in the box, today's date is always displayed when I run the application. Rich Didn't make myself too clear there, it is both a "calculated value" and also one which can be reset by the user. Anyway, I made the date/time picker invisible and dropped a form ...Show All

• Smart Device Development How can display Transparent PNG on the device based on WinCE5.0 by eVC

• Visual Studio Code and Build metrics with MSBuild

  Hi all, I am new to MSBuild and I am trying to gather various build metrics (such as number of errors/warnings, historical build success measures, etc.) . I also want to format the output from the logger (hopefully a pre-built one) in a structure which cuts out the redundant information but leaves the relevent information, perhaps in XML I also need various code metrics such as No. classes, lines, comments, % of comments, etc. I find MSBuild easy to use but if I could find a way to do all this it would be perfect! Is there anyone out there who knows how do do these things or knows which utilities are needed to do so Any help greatly appreciated! cheers!

Any advise Thanks in advance! 'Executed as user: test.com\admin. A required privilege is not held by the client.

• Software Development for Windows Vista Using Windows SDK (With the Glass Effect)

  I have Windows XP and I downloaded Windows SDK for developing apps that are compatible with Vista, is it possible to make an app on XP with the glass effect or do I have to use Vista to create an app with the glass effect Hi Sniper, The Aero glass effect is something that is unique to Windows Vista else we would have seen such apps on XP itself by now. However you can get a "little" close to that by using the Opacity property of Windows Forms and the effect can be seen on XP as well... even on Windows 2000 for that matter. A bit of smart and careful super-imposing and you should be able to get a little closer. Though you cant still compare that with the now famous Glass effect of Windows Vista.

• Visual C# idle detection ...

  I am developing an application with multiple forms and user controls embedded in panels. After an idle time interval – by that I mean an interval of time when the user does not interact with the application - I would like to launch a form. The stupid way of doing this would be to create a method to manually restart the timer time interval and then explicitly call that method from all “click-handlers” of all form components of all forms and user controls …. I don’t want to do it that way. What is the nice way of doing it, what message/event should I capture to restart the timer interval only from one place Thanks for your help, Dom. Check out Application.Idle , it raises "when the appl ...Show All

• Commerce Server Discounts - Buy Product A get Product B for X% of the cost of Product A

  Consider the following fictional scenario: An automotive manufacturer wishes to offer a GPS Navigation system for their entire fleet of vehicles as a “cross-sell” item. The cost of the GPS system is proportional to the cost of the vehicle. They have decided that the Nav System option is 5% of the total purchase price of the car. Some examples: A car that costs $35,000 can have the Nav System installed for $1750. (5% of $35,000) A car that costs $65,000 can have the Nav System installed for $3250. (5% of $65,000) Is it possible to configure such a scenario within Marketing Manager (Buy product A and get product B for X% of product A) If not, has anyone customized the marketing/discount ...Show All
