• Windows Forms Datagridview KeyDown Event

  I have a datagridview bound to a datatable. I want to have the Enter key move across the row and not down the column. I can catch the Enter key with a KeyDown event to use a SendKeys command (not very elegent), but when the cell is in the edit mode, the KeyDown event is not fired when the Enter Key is pressed. The focus moves down the column. Any ideas Hi Scott, I also had thesame problem and use this as a solution: it is not yet perfect though, but perhaps  you find it usefull: public class DataGridViewEnter : DataGridView     {         const int ...Show All

• Visual Studio 2008 (Pre-release) table of data

  I need to display the contents of an XML file in tabular form. The basic structure of the XML is; <table> <row> <column_name_1 /> ... <column_name_n /> </row> </table> where column_name_* etc could be <name>, <age>, etc. For example, <table> <row> <name>Bob</name> <age>32</age> </row> <row> <name>Alice</name> <age>23</age> </row> </table> Which should result in a table thus, [name][age] Bob 32 Alice 23 Unfortunately, what I am seeing is [name][age] 32 32 23 23 Obviously, my binding logic ...Show All

• Windows Forms Updating data files

  Hi all, I have a winforms app that I want to deploy via clickonce, largely because there are 3 large xml data files that will be periodically updated. These files are lookup only, and WILL NOT change on the client. First, I'm running the RTM of visual studio, not beta or RC in case that makes a difference. Now, when data is changed in a table on our sql server db, a trigger will force these xml files to be recreated, and then the files must be re-deployed so that the client receives the updated lookups. I've looked at two ways to do this... Mage, and using MSBuild so that the trigger can just call a batch and have everything done. When using ...Show All

• SQL Server Data access by creating functions

  A number of time I have come accross developers using functions like GetProduct() GetProductTitle() GetProductCategory() to get the value of the data instead of just using queries / stored procedures Not UDFs but functions in VB and in DLLs I have not understood why can you please point to some good forum messages / blogposts / articles on this Whats your take on this The main reason for this is to separate your code into layers. When you create this function, then you could have different database implementations inside of the function, like data from SQL Server or Oracle, but to outside world, that ...Show All

• SQL Server Log Folder Creation

  My Log file connection is set to "Create Folder". According to BOL, this seems to indicate that the folder(s) that the log file will reside in will be created if they do not already exist. Yet I am receiving a package validation error when I execute the package. The full error is: The SSIS logging provider has failed to open the log. Error code: 0x80070003 The system cannot find the path specified. As a side note, I thought that setting the connection to "Create File" would recreate the log file each time it ran but that does not seem be the case. Instead, the file gets appended. T ...Show All

• .NET Development How do I get or set IV and KEY for Symmetric Key in MS SQL Server 2005?

  All Symmetric encryption algorithms have to have Initialization Vector and Key for Encryption/Decryption. It is possible to generate and save them for future use in VS 2005. How do I do it in MS SQL Server 2005 ! I beleive that it has to be such parameters, but I could not find them ...

• Windows Forms how to move from Form to Form?

  I am building an app that requires a user to complete info on a form, then click "Next", complete more info, then click "Next" again. Also, the user can go back at any time by clicking "Previous". It's a wizard-like interface. Anyway, I am currently doing this to go to the next form:             Form2 theForm = new Form2(SomeObject);             theForm.Show();             this.Hide(); This works fine, but I suspect that I shouldn't be doing this. For starters, I am really just hiding Form1, so it is hangin ...Show All
