VS 2008 Cannot Seem To Get A Working Filter In Working Order
Jun 18, 2009It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

2- now that i have got the new balance and the product oder has been made so every time this happens a query has to be sent to change database or there is any other better why of doing it?
Working With Remote Database?
Aug 23, 2011I am a long time VB.NET developer but all my work has been on local databases. My employer now wants me to send data to a remote MSSQL Database without exposing the database. So, I think the answer is webservices. Except - I have no diea how to use this? I only know the word from my basic Google searches about this need.What we are trying to do is have a button in Outlook that allows the user to send the email to our CRM database.
I have been able to parse the email fields I need. How do I go about sending this to the database now? I also need to be able to read data from the database, so the user can select which customer to tag the email to.

SQL Connection - Creating And Working With Database
Jan 7, 2010On my development PC I have SQL Server installed, and my SQL connetion works perfect. I use a trusted connection. But on other PCs, where the program should work later, there is only a SQL "Express" installed (by another application), and it seems they have an password on the SQL Server (I guess). I have no chance to get the password from the other application. My connection is not working here. I created some connection test, but it does not seem to work with the trusted connection. I need the SQL only for creating my own database and connecting to my own database. So how do I create a connection with SQL Express for creating and working with my own database?
Here my code for testing the connection so far (Fehler means Error, erfolgreich means Success) Private Sub mnu_Verbindung_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnu_Verbindung.Click

Formatting Currency (U.S) Not Working With Data From Sql Server Database?
Mar 25, 2012I have a code that binds the data from the database to textboxes. The problem is I want to make one of the textboxes Payment use a dollar sign.I tried formatting it as shown in the code below but only the first record gets formatted, the rest do not. When I click the next button, the dollar sign disappeared.
Here is a portion of the code:
bs = New BindingSource(ds, ds.Tables(0).TableName)
Me.txtPayment.DataBindings.Add("Text", bs, "Payment")
Me.txtPayment.Text = Format(CType(txtPayment.Text, Decimal), ("c"))
I have tried everything else I know, FormatCurrency but no luck.Payment is the name of the column in the database, the data type in SQL Server is Small Money.

Optional Parameter Not Working When Trying To Pass Null Value To Database?
Apr 10, 2009I am hardcoding an insert statement to a database, based on certain details a user enters into a windows form. The form has a few textbox and datetimepicker controls for the purpose. This form enters a single row in a single table in the database.The table has a few possible null columns defined, in those cases where the user does not have any data for those columns at that particular time.
I have to provide controls for passing data to those null columns nevertheless. In my case, I have two such columns that accept null values, and two corresponding controls - a textbox and a datetimepicker. The datetimepicker has a checkbox added to it so that if it is supposed to be null it doesn't pass the default current date value, and remains unchecked to explicitly specify that it is supposed to be null. By default it is unchecked.
My code is structured as follows:
Form1:
'the sub referenced here resides in a dll file in my dataaccesslayer code, and in my actual example is referenced properly.
'I have shortened the code here for simplicity
[code]....
Now it gives me an error whenever the code comes to the executenonquery(), and says something to the tune of "SqlDateTimeOverflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."
I think the value of 'Nothing' from the subprocedure's paramter is not being assigned to the sqlcommand's parameter as a database NULL, which is what I need to pass to the database.I know instead of using optional parameters I can easily create overloaded subprocedures where one sub allows not passing values where the column(s) is supposed to null and other overloaded subs permit combinations of which column(s) are null or not. But it is simple as long as there is just one, or at the most two null columns in a table. If I have dozens of null values in a table that the user can choose to enter or not in a data entry form?
