What Is The Purpose Of The Function CLine
Jul 21, 2009What is the purpose of the function CLine, because it is used in my code and it isn't a member of the namespace it is attached to in the vb6 code pasted straight into visual studio 2005, what would it do in this context:
frmXML.CLine = 1
frmXML is a visual basic.net windows application.
Database - Running SQL Query From Module With A Function Call From The Form?
Jan 28, 2010I have a form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()
End Sub
Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?
Debugging Execution Of Database Function Call To Remote Sql Server?
Sep 14, 2011Working in VWD 2010 Express I have an aspx.vb file with the following connection string:
Protected Function getPasswordLength() As Integer
Dim conn As New SqlConnection("Data Source=localhost;database=MyDB;Integrated Security=true")
Dim cmd As SqlCommand = conn.CreateCommand()
[code]....
This works when the code is on the web server / which is collocated with the SQLServer.However, when I want to debug, I have to copy to the server. I would like to be able to "debug in place" on my development machine and only copy files to the production machine periodically. Technically the production machine is not in production at the moment, but that's beside the point.Anyway, I followed the following instruction: [URL] I can now see the remote database, functions, etc. on the other machine (from the VWD running on the development machine). However, I thought I should then be able to execute this same code locally on the development machine using ctrl-F5, but I get the following error:
**Server Error in '/' Application.A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)**
Time To Call A Function To Change Data Being Returned From Database?
Jun 28, 2009I have two functions written in VB.NET:
1) The first function (call it GetValues()) returns values in a SQL database as a list via a stored proc. One of the fields is DateTimeSubmitted. All of this data is displayed on my webpage using a repeater control. It works fine.
2) The second function (call it NiceDate()) I created to change the DateTimeSubmitted to a nice date such as "one minute ago" or "yesterday".
My problem is I have no idea which is the best part of the process to do the conversion (at point of data extraction or in pageload etc.) or in fact how to do the conversion.
Database Veiw Adding A Update - Delete And Email Function From The Selection From A Checkbox
Sep 19, 2009I am pulling information out of my Access Database and reading to a webpage. I need to add a update, delete, and email function to this page. I am trying to do this with the selection of a check box and buttons for each one. But I am unable to get the delete to do anything but redirect back to the orignal page. For the update I want to be able to pull the info in text boxes and just change the info and click update and it gets changed. I also want to be able to pull their email from the database and put it into a text box to be able to email right from the page. Code for show page and delete page below.

Database - Replacement For Ms Access Db For Multi-LAN User Purpose?
Apr 27, 2012I have been using access for my applications from over 4 years now. I realize its time to move on now and i need suggestions for a new database. Here are my requirements :should be able to connect it with Vb.net windows form frontend GUI - all database functions such as add/delete/edit/update will be done through the vb.net front-end only.Should be able to place the db on LAN and each client on the LAN can then access the centrally stored db through their individual front-ends.At the most 5-6 users will be reading/writing to the database at the same time , so the database should not crash or slow down Since i come from MS access background, i would like something thats similar to it so that i can learn and adapt to it quickly.Not very important, but i think its worth mentioning. This db will be the main central db for my .net application.My .net application will also be interacting with quickbooks and magento via some apis but ultimately all this data will go to the central db. So just curious, will there be any compataibility issues with the database that you suggest Should handle about 10 tables and around 10k records in each table Should be secure - just that i should be able to lock it up or anyhow prevent it being accessed from anywhere else other than the vb.net front-end.
Lastly, I would prefer it to be free to use if possible but not essential. I realize there are some topics like mysql vs sqllite and on databases, but pls understand i need suggestions for one that will be apt for the purposes i have listed above.
Edit : Just curious - Would i pushing the limits if i still stick to access - i understand access won't be good for multi-user access but i guess 5 users is not much ?
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:

View 1 RepliesCall A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?
Sep 14, 2010I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
Call A Function / String That It Uses Will Be Given To Function To Initiate A Download?
Aug 21, 2009Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

View 2 RepliesCall A DLL Function?
Nov 28, 2010I have created a new Class Library in visual basic and called it 'TestDLL'. I have a TestDLL.vb file where I put in this code
Class TestDLL
Function ReturnHello() As String
Return "Hello"
End Function
End Class
Then I clicked on the build tab and built the solution. I then copied the DLL 'TestDLL.dll' to C:TestDLL.dll
I am trying to use that DLL in a console application. I have tried this code but I get an error: System.EntryPointNotFoundException was unhandled Message=Unable to find an entry point named 'ReturnHello' in DLL 'C:TestDLL.dll'.
Declare Function ReturnHello Lib "C:TestDLL.dll" () As String I have added TestDLL.dll to the references for the console application and got that to work, however my goal is to load and unload different .dll files without restarting the application. I have a lot more code besides this, but I'm just trying to find out what commands I could use for just calling functions from DLL files.
There was something I was reading about assemblies, but all I get that to do is list the classes in my dll file. I will already know all the names and locations of the .dll files, and also the class and functions that they contain, because I will be building all of them. how I can get a simple function return in my console application.

Call A Function On CD Change?
Jan 26, 2010I've got a program that has a text box with a list of files that are on any removable media. Suppose you launch the program and there's nothing in your CD-ROM drive. Right now, you'd get nothing, and you'd have to insert a disc and click a "refresh" button, which triggers a function that repopulates the list.
Is there any good way to call this function on the event that the user inserts/removes a CD-ROM from any CD-ROM drive? Also, inserting/removing external disks and flash drives? Without having to constantly poll the drives. Floppy disks aren't important to me.
