• Visual Basic Getting data from a database using a primary key

  Hello. I am having trouble with a program. I want to be able to get some data from my database table, given the value of the primary key. This is what I have so far: projectName = DbDataSet.Projects.FindByid(projectId).name where projectName is a String, and DbDataSet is my dataset. The variable projectId is the ID of the row I want to extract the data from, but every time I run my code I get a NullReferenceException. I know that the row with the primary key value of projectId exists because I can see it when I view through server explorer. Any help would be fantastic Bryan St. Amour You have several objects ...Show All

• .NET Development DataGridView + DataAdapter Edit Weirdness

  Hello, I originally posted this thread in another forum but someone suggested I repost it here: I have a DataGridView setup with a DataAdapter.  There are a few fields on a couple of rows that I update programatically which causes the DataAdapter to want to update the data in the database every time I run the DataAdapter's Update method.  Is there anyway to set the status of the row to NOT update the database (at least until a user edits something) Thank you -Adam Plocher Hi, Ooops. Forgot about that. You could just call the DataTable.AceptChanges() method to mark all of the rows into Unchan ...Show All

• Visual Studio Team System How to avoid Designer classes

  How do we avoid throwing warnings for Designer class variables like resourceMan, resourceCulture, temp etc. And how to avoid system generated methods like .cctor etc For cctor's, check whether a Method is actually a StaticInitializer, eg: if (method is StaticInitializer) return null; To eliminate certain members, you need to examine the member.DeclaringType. The easiest thing to do is look at Member.DeclaringType.FullName and compare it to the type name you want to exclude. Don't forget to keep walking up the inheritance hierarchy (by examining the declaring type BaseType member) until it is non-null. We will probably prov ...Show All

• Visual Studio Express Editions Appending text in textBox control

  Hi All, I have a webBrowser control in my C# winform app. This works beautifully and I have a textBox control (called txtAddress) as the address bar. This also works beautifully apart from one small detail. I have noticed that when typing in a URL to navigate to I have put http:// at the beginning of the address. This is not a problem for me but I know that some of our users will only put the www at beginning of the addy. To get around this problem I thought about composing a method that invokes before my navigating method that checks to see if http:// is at the beginning of any text inputted by the user into txtAddress. If it is no ...Show All

• Windows Forms Datetimepicker bug

  i have a datetimepicker with a showcheckbox property set to true. I set the format of the date to MM/dd/yyyy so that i can input numeric dates. But everytime i input the numeric dates the cursor focuses on the checkbox control. This is obviously a bug. is there any workaround to this problem please help. To attempt to clarify your issue, you have a DateTimePicker on a form with other controls. Programatically setting the date of the DateTime control forces focus away from whatever control had it before to the DateTimePicker If that is what you are stating, I have not seen this behavior. The CheckBox does get the yellow focus, but doe ...Show All

• SQL Server Create 1 connection to execute multiple Packages

  I want to create 1 connection because I have to execute multiple packages (2005). But when I go into the execute package task editor, the dropdown only ever has "New Connection". Is this a bug "Why can't the EXECUTE PACKAGE task just use one of the connections available in the "connections managers" collection " It can, If all your execute package tasks are in the same package, yes, they can all use the same connection manager. Is this not working for you Whew, thats all i need, maybe its a bug - using June CTP. I create a new execute package task and then create a new connection for it. Then I c ...Show All

How can I format a decimal number in the following manner 6.000 ---> 6 2.5 ---> 2.5 I want to format the decimal so that the trailing zero as well as the decimal point will not be shown in case of a whole number.   Hi, You can do your formating on the string format. dim d as decimal dim s as string d = 4.0000 s = d.tostring("0.#") ' add additional # for decimal places to be round off ' you can use also the formating of d.tostring("0.0") or ' d.tostring("0.00") add "0" after the "." to set the nos of decimal places the result of s ...Show All

• Smart Device Development Catch power button event

  I'm trying to understand what happens behind the scenes when a user hits the power button on a PocketPC WM 5.0 device. My goal is to capture/prevent the event that causes the device to go into suspend mode, prompt the user to confirm their action, then continue accordingly. I'm an ISV trying to guard against an accidental hit.

• .NET Development Never trust a tickcount

  Hi, For those who use tickcount for any calculation on your application... DO NOT USE IT. Simply, for some idiot reason the tickcount returns an integer, so if you have a server that runs all the time or if you have a multiprocessor environment the tickcount overflows and returns 0! But for my surprise if you use Tickcount.ToString() actually returns the string version of a 64bit value, so is not 0!!! Funny when you are trying to debug your application and ToString() says 43453345345444 but the property returns 0 One of those funny things, pretty sure that tickcount internally is a 64 bit value and the property cast it to a 32bi ...Show All
