I don't know what I've done bad, or what could have caused this bug : when I submit this form to the controller, the controller receives 2 empty fields here is the form inside the view :
@Using Html.BeginForm("contactSearch", "search", FormMethod.Post)
@Html.TextBox("SearchString")
@Html.DropDownList("opportunite", "Choisissez une opportunité")
@<input type="submit" value="Submit!" />

I am running Visual Basic 2008 express edition. My controls toolbox is empty. There are also no properties for the form controls on my project. Just blank. I have removed the .net framework v2.0. I had the .net framework v3.5 installed at the time, and thought I didn't need the older version (v2.0). Do I need v.2.0 for the tools? If so, where can I get a copy? What's the filename called?
View 2 RepliesI have an array set up to receive the names of forms when they open. The form name is sent as a Form not a String therefore when I run my code I cannot check for whether the field is empty in the normal way (ie. array(1) = "") as the "" are only usable with strings!

I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into SQL it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction?
Here is the required part of the code, if you require more just let me know.

So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL. What does an empty form field equal? in classic ASP it was always "".
When the form loads it reads from an embedded resource file that loads the data into variables. It then uses mid(variable,1,1) to load a single value into a textbox. It does this for a total of up to ten textboxes. Sometimes all the values show up sometimes some, sometimes none.

I have a blackbox (with a crude ftp server on it) which has an IP address, a file on it, a username and a password. I have a PC logged on to the local network and I want to write a VB.net program that sits on the PC and when the file is created it downloads that file. from the laptop I can type ftp:192.168.43.34 in to windows explorer and see the file without having to type in a username or password (username is set to Anonymous)I require a simple program that just points to the file (ftp:192.168.23.12/banjo.txt) and grabs it to a local path (C:\banjo.txt)I have looked everywhere and not found anything that works and not interested in paying $500 for a library.

View 1 RepliesI have an application that has multiple UI layouts, sometimes on tabs, sometimes the occasional separate form.I recently bought a pack of UI elements, and I'd like to use a ribbon control as the main navigation. For the most part I want the tabs on the ribbon to function like your everyday tabcontrol. The problem is that the ribbon tabs don't each have their own page for you to lay out your controls like the normal tabcontrol does.So right now I have the ribbon control at the top of an MDI form, and instead of using multiple tab pages I have many borderless forms, and when I click on a tab of the ribbon, I maximize the appropriate form and bring it to the front. This creates the illusion of tab pages by eliminating the control boxes of the child forms.

I have built an application a while back and now think that performance would benefit from a MVC approach, so I am looking into that.

View 6 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

I have a table with several rows of data that I need to return to the controller. In my view, I initially load the table by selection of a time period and clicking a button. The table loads all my relevant records but one of my table cells contains a dropdown list. So I should be able make a selection in the dropdown click "update" and my controller saves the changes.
So everything works until I try and save. The model that is sent to the controller is completely null. The list property I have tied to the table cells returns to the controller null.
