• Windows Forms Windows Services

  Hi all, I'm working on a project that requires a windows service. I've never developed one before so I have some questions... 1. In all the examples that I have seen so far it looks as though a Win service requires an installation project... Why 2. Are there any registry entries that are made when the service is installed if so what are they 3. If a service is executing a stored procedure in a remote database, does the service need to open a specific port If so is that something that is configured in the service code or properties Thanks in advance... In general Windows Services do need some sort of installer, I know that when ...Show All

• SQL Server SSAS Project Deployment problems

  I need to deploy my SSAS project to another server. On that analysis server there is a database, and it has a role with full control, and I'm added to that role. When I try to deploy my project I get the following error: The database , 'MyASProject', contains an ImpersonationMode that is reserved for server administrators. I know that in the SSAS Project, in Datasource Designer, there is a tabsheet called Impersonation Information and in Management Studio, in the ASDatabase property page there is a property called Data Source Impersonation Info. I played with these properties, I must have tried every possible combination but it ne ...Show All

• Visual Basic Accessing images stored in Access database with VB.NET 2003

  Hi, I am developping an employee management application with VB. I used an Access database to store employee information and the pictures. However I have a difficulty at displaying employee images. I have found some code to add images and display them on the form. The code, first reads the image stored in database (in binary form) then writes in a temp file and then uses a picturebox to display the image on the form. Code is working fine but when I try to add a picture for an employee and then try to change (another add operation) the employee's picture right after addition, program crashes because the temp file is already in use. Can y ...Show All

• SQL Server Execute SSIS package from ".vbs" file

  I need to execute a SSIS package from a ".vbs" file on a computer that don't have SSIS installed on it. Thank You You can use ADO (from VBS) to call sp_start_job for an existing SQL Server Agent job, or even create a new job and then start. SSIS is not client/server as per SQL Server, it executes the package on the host machine. You need to use another technology to communicate wth the "server", hence the suggestion of using SQL Agent to host the process. ...Show All

• Visual Basic Dynamically Changing Button Properties

  I am writing an application where I have a 5x5 array of buttons that I want to dynamically update some of the properties. I have created all of the buttons in the editor and have given then names that reference their position in the matrix (i.e. btnGrid11, btnGrid12, etc.).  Based on the button that a user presses, I would like to update the image that is shown. I would like to do this in a loop and the problem that I am running into is that I cannot figure out how to dynamically reference an existing resource.  This is an example of what I think the code should look like.  I was thinking that I could create a button resource ...Show All

  Hi, Do you know what's the different between "equals" and "==" No, you *can* use == on string variables, as System.String overrides == operator (note that both sides must be string variables, otherwise System.Object's == operator is called, which does a reference comparison)   string s1="Test"; string s2="Tes"; s2+="t"; /*prevent string interning*/ Console.WriteLine((s1==s2)) //prints True   ...Show All

Just so that I have said it: You should have a really good reason for doing this. I can't say I can imagine why you shouldn't ask the user to remove the program with add/remove programs. Still, if it is urgent, here goes: You would need to find the program by searching registry in the folders directly under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall 1) Search for name matching the application to ...Show All
