• Software Development for Windows Vista Adding roles to WorkflowRoleCollection

  Hello, I'm developing a workflow with ASP.NET authentication. I have assigned some event handlers in the workflow a WorkflowRoleCollection in their Roles property. When I want to fill the WorkflowRoleCollection with the roles that can raise the event, apparently I don't do it right. The problem is that when I raise that event I get an exception saying something like "authorization error in eventhandler guardaHorari1", and by checking the exception details I've thought that the problem is that when it checks the role of the user that tries to launch the event agains the workflowrolecollection, it doesn't find it there. I fill the collection this way: public WorkflowRoleCollection rolsModificadors = new WorkflowRoleCollection(); ...Show All

• Windows Forms Is Form Height limited?

  Why isn't possible set Height value for windows form greater than 1044. When I write bigger value is automatically repaired on 1044. Thank's for any idea. I tryied create new Windows Application project. In a Form1 a try set Size.Height to 1200. It isn't possible because value is repaired to 1044. I need long form and need design it. But it isn't possible and I don't know why. In a new project I don't specify any windows size. May you set Height bigger than 1044 in a new Windows Application ...Show All

• Windows Forms How to determine if DataGridView contains uncommitted changes.

  I have a form that uses a DataGridView, BindingSource, DataSet and BindingNavigator to edit a single table in a database. When the user picks the 'X' in the upper right corner to close the dialog box, I need to determine if there are uncommitted changes in the grid, so I know when to ask if they want to save their changes. I'm thinking I can set the current cell to the first cell in each row and call 'isCurrentRowDirty'. Is that the proper way to do this Thanks, Mike Or a really simple way: Use events beginedit and endedit from datagridview. Store the cell edited in beginedit. Check to see if the value changed in end edit. If it has, then set a flag. If the flag is true, then ask them to save. No nee ...Show All

• Windows Forms hold a key...

  is there a way to "codely" press and hold down a key for x amount of seconds Apparently it is a VERY special key...cuz VB doesn't even talk about it. I tried your suggestion of {fn} but I get an error that it isn't a valid key....plus I need to have a way to combine Fn with F8 to get the desired effect...the syntax simply doesn't allow something like {fn}...needs a + or % for example. I wonder if there is another way to set the LCD/LCD + Monitor/Monitor sequence rather than the Fn+F8 ...Show All

• .NET Development Formatting numbers

  .net I am building a solution that shows two numbers. VAT on sales and VAT on costs. I can obtain the two values through a SQL query Sum(amount) * 0.175 etc etc however when I want to subtract one from the other I get a single digit number. For example my sql query might return 14,5435.00 and 5,746.00 but the value i get after i try to subtract them is 9. I have tried using format but that just returns a letter "N" in this case. Label35.Text = Format(objDataRow.Item( "totalclientyear" ), "N" ) objDataRow.Item("") return an object. You need to convert the data to a number for the format to work Label35.Text= CDec(ObjDataRow.Item("totalclientyear" ...Show All

• Visual Studio Express Editions Have I choose the right programming language for my project?

  Dear all, First of all, I'm a total beginner who wished to create a software for my own small company. I read around about VB Express and SQL Express, and being free and supposedly easy, it caught my attention. Not to mention excellent forum support as well. I would like to ask for advices from the VB seniors here at Microsoft forum. I just want to make sure that VB Express will be sufficient to make a program that fulfill my desired feature: 1.Compiled as a standalone installation file. 2.Multi user capable. The program is to be run by several person in my company (probably 2 - 3 person) through local network 3.Password protected some specified table, so that only admin that can alter them. For example: item price in Item Table can only b ...Show All

• Visual Studio 2008 (Pre-release) Getting DLINQ to work in existing projects

• SQL Server CREATE ENDPOINT failing with no errors

  I'm hoping someone can shed light on a problem. I'm running SQL under a service account on a Windows 2003 R2 SP1 machine. The machine is also a domain controller. When creating an end point I get back a success message and can view the endpoints in sys.http_endpoints. However, when using httpcfg query urlacl there are no end points registered with http.sys. Using IE to try and access the /SQL wsdl returns a 404. There is nothing in the event log or the sql logs about any failure. The same TSQL code works fine on a development server. I've added the code below but am guessing its a permissions problem. I've followed the instructions at http://msdn2.microsoft.com/en-us/library/ms184379.aspx including SPN registration for the ...Show All
