• SQL Server Client Render broken after upgrade to Win2K3 Enterprise from Standard

  First off, any suggestions are welcome here as we're lost. We have a farm of 2 Win2k3 (standard) servers that had a couple GB of RAM. We then installed 16GB of RAM and upgraded to Win2k3 Enterprise to handle the upgrade. Prior to the OS upgrade our reports rendered as expected. Post upgrade, they do not. Some background on how we render...we open a PDF rendering of a report in a popup via JavaScript. Also, we have 3 environments running the same code base. The only difference between the 3 is that one environment is the one we upgraded to Win2k3 Enterprise. Again, any suggestions are much appreciated! Scott Of course, I forgot to add what's probably the biggest key. Only clients have thi ...Show All

• .NET Development Close sqlserver connection, but using sqlquery commands, hard to explain

  I would like to close a sqlserver connection, but using sql query commands. What I need to do is close a connection from a steal user password account. this is the scenario: I made a system where every password can only run one at the time, so you can not run the application in two or more computer using same password. So, if when you try to run the app using your password and the system give you a message error about that another user is already working with same password, you can have the option to close the another user's connection, doing that the system can give you access and only one account(password) should be working at that time. This is because I sold this system base on password's Qty: 1-5, 6-10,... I can not handle this in a t ...Show All

• SQL Server Changing ASP Application to use SQL Native Client

  I am attempting to change an ASP application we've got to use SQL Native Client instead of MDAC and running into a problem. If I use ODBC driver our application runs without problem, but if I try to use the OLEDB provider certain pages are throwing the following error: Item cannot be found in the collection corresponding to the requested name or ordinal. The pages that are not working are using ADODB.Command object to execute a Stored Procedure and populate ADODB.Recordset object. The error is thrown when I try to access a field (by name or index) in the recordset. I am using recordsetname(0) or recordsetname("fieldname") to access the data in the recordset.

• Visual Basic mapping an onClick event to runtime created menu item

  I am trying to create a "recent files" list in a dropdown menu in my application. So I have to add a list of files to a dropdownitemlist when the program loads. I am using the line below to add the a new filename to the list. What I don't know is how to map an onClick event to a newly created object such as the mystripitem below.

• Visual Basic Compiling C code functions to call from VB

  Hi I have a chip I need to reconfigure via a VB app. The company provides a C code API to do this (i.e. their software generates *.c, *.h files for us to call). I don't know C, but I want to compile it as a dll file to reference from my VB project. The files are plain C. Which wizard settings should I use, so that I can compile and link to it to access their functions from my VB code I have tried to do this, but keep getting an error message saying it could not add it as a reference: ...make sure file is accessible, and that it is a valid COM component.

• Visual Basic Overriding Enum members

  How can I override or overload Enum public methods e.g CompareTo or ToString I know that this sounds like wierd.... But this is what I am trying to accompolish... Take an e.g. Enum Numbers One=1 Two=2 Three=3 End Enum What I was trying to do is to override the ToString or the GetName method to return a string other than the enumeration name. Like Dim a as Numbers=Numbers.One Now, I was trying to get something like "Oneself" from the overloaded version of GetName or ToString. I know there could be other methods of achieving the same effect (Collections, or arrays or even classes with Public constants), but I was hell bent on doing it with enums unless I realized that it couldn't be.... ...Show All

• Windows Forms Combining ClickOnce and MSI Installer

  Hi, I have been surprised by the gap there is between ClickOnce and MSI. And I need to solve this. The scenario is this: Install a windows form application on a client (registry values, files, folder creation) and use ClickOnce to just update the application. Any GOOD documents about it Thanks!!! OK. Let me try to explain: 1.- You will need to create an Installation project (MSI) and finally get your app.msi file. 2.- Need to download the Bootstrapper SDK which contains the Bootstrapper Manifest Generator ( http://www.gotdotnet.com/workspaces/workspace.aspx id=ddb4f08c-7d7c-4f44-a009-ea19fc812545 ) 3.- Now you need to create a Package Manifest. 3.1 – need to add the MSI you just generated. 3.2 – Follow ...Show All

• .NET Development Detecting remove lock event on file

  I have the following problem: We have to write an application that acts on changes on files. For example editing a word - file. We achieve this using the FileSystemWatcher from .NET 2.0.  When the word-file is saved the events correctly trigger, but the files are locked, which causes our action to fail, but this is not the problem. But when the user closes the word-application. The application release the lock,but  we can't seem to catch this event so we could run our actions then.   Does anybody has as solution Thx, gert So if there is no explicit windows way to detect a lock, we are back to an old-school trial and error approach to find out whether there is a lock ...Show All
