• Visual C# Update DataGridView?

  I have following code for the form closing event: private void CurrenciesList_FormClosing( object sender, FormClosingEventArgs e) { dataGridView1.EndEdit(); if (dsCurrencies1.HasChanges()) { DsCurrencies chngs = ( DsCurrencies )dsCurrencies1.GetChanges(); sqlDataAdapter1.Update(chngs); } } Now, problem is the current cell: when I close the form changes on the current cell are not updated if I do not leave the current row. If I close form while I am still in the row all changes to this row are not accepted. It is like this that method EndEdit does not saves the curent row. How can I save current row in the DataGridView I guess anoth ...Show All

• Software Development for Windows Vista Handling exceptions in workflows

  I must be missing something basic here. I understand how to use the FalutHandler activity. But what I don't understand is how exceptions are handled by it. My example is a console workflow app. I set a connection string in code and connect to a database using conn.Open. But I purposely mess up the connection string and the connection fails. I have a FaultHandler with FaultType of SqlException. But at runtime, when the exception occurs the Framework handles it for me and I see the error message in Visual Studio. If I click Continue my FaultHandler code executes. Why is Visual Studio showing me my exception rather than letting the FaultHandler handle it The same thing occurs in the Nested Exception Handlers sample. This uses Thr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Need some basic information - i.e. help. :-)

  We are looking at performing some work for the Army using this XNA technology. Before we jump in with both feet, we were wondering if someone could answers some questions: 1) Can we perform complex motion such as a person walking 1a) Can it be automated such as bi-ped motion 2) Can math equations be used such as wheel rotation matching the ground distance 2a) Can this be automated Any other help / links would be greatly appreciated! Thank you! (moving to XNA forum) Check out the FAQ in the XNA forum there are planty of websites with tutorials.

  GS provides a flexible way for users to generate new primitives. We want it is more flexible. If we emit some new primitives without use any input data such as position or color.

• SQL Server visibility for a field

  I have a field on a report where on occasion, will display 'PR'. We need to have this field hidden if that is the value of the field. I wrote an expression for visibility like: iif(Fields!ThisName.Value="'PR'", false, true), however it still diplays. Is there something else that I need to do here Thanks for the information I think I did find the problem. The data is being pulled from an AS/400 database through SSIS, but there are trailing spaces. So now I tried this =cstr(Fields!ThisName.Value).TrimEnd="'PR'"; however now I am getting "The hidden expression for the textbox "TTLNAME" contains an error: Object reference not set to an instance of an object." ...Show All

• Visual FoxPro Object assisted report in dot matrix printers

  I encountered a problem using object assisted reporting. Preview works fine but when I tried printing it in dot matrix printers like Epson FX-890 or Epson LQ-2170, it printed smaller fonts and the whole letter size paper was only printed 3/4 of its size, what could be the problem To further determine the cause of the problem, I tried printing it using report behavior 80 and it came out fine, thus report behavior 90 is to be attributed as the problem for these printers. Please enlighten me on why this is happening. Thanks.   i think this is VFP bug. my partner also reported having problems with dot matrix especially with customed size paper. ...Show All

• SQL Server Ignoring NULL values in LOOKUP transformation.

  Hi, Can you please tell me the way to configure the LOOK UP transformation so that it will ignore all the null values I want to configure a Look up component for the column "Col1" as follows All the NULL values of Col1 should not be considered for look-up process. They should be passed to the downstream component as valid rows. All NOT NULL values of Col1 should be processed by the Look up component. If there is no matching value present for any NOT NULL value of Col1 then it should be directed to error output. Regards, Gopi Frank, Thank you for your reply. But, Is there any way to avoid conditional split I would like to configure Look up component itself ...Show All

• Commerce Server Custom and Orders Manager crash

  After I add a credit card to a user's profile and then I try to open the user's profile in the Customer and Orders Manager, it crashes. If I debug it, the error is: A property value provided in the profile XML could not be persisted to the underlying data store. Validation of the property value failed. Profile Type = 'CreditCard' Which is odd, because this used to work fine. The only thing that I recently changed that remotely might affect this is I extended the orders system by adding two weakly typed custom properties. These are working fine for me. Any ideas on how to proceed Best Regards, Brad I'll answer myself on this in case someone has the same problem. I tracked it down to the Customer and Ord ...Show All
