The company I work for has given me VS 2008 to build a Data Entry form. They want me to put check boxes, which I've done and now they want a drop down list that when selected pulls up different check box items that populate into a different screen. I'm new to this, but don't feel it should be that hard.

View 1 RepliesI need to build a rather simple form for collection some information from our membership. It has 4 Text boxes and one Submit button. The contents of the text boxes need to be emailed to a fixed Address and a fixed Subject. Before I got to fancy I tested the form to see if the email portion worked which I did get the email but not all the data. I am trying to stick with VB as I had experience with it years ago.
My problem seems to be in building the string for the body of the message. Trying to use StringBuilder but my syntax is messed up somewhere. The Fields that I have are: Name, Phone, Email Address: and Comments. They are named in the form as txtName, txtPhone, txtEmail and txtComments. [Code]
I was trying to find examples of how one would make a webpage using asp so that I could have the visitor enter information on a form and then when they hit submit it will be attached to my webpage indefintaly and any visitor can view it.
View 4 RepliesI'm building a form with just a combo box in it that contains a list of other forms that I made. I want to program the combo box so that if a user opens it and clicks on "Web Browser", that form with the combo box will close and the web browser that I made will open. Another example is that if a user selects "Media Player" from that combo box, the form with the combo box will close and the media player that I made will open. How would I program the combo box to do this?

I have written a program in VB.NET 2008 Express that references a .NET managed dll. I simply added a reference to the dll to the project. I then 'Imports' the dll at the beginning of the program and then can use it. Everything works fine when I am running the program in debug mode (and it uses the dll as intended), but as soon as I go to build the project I get an errors that it "Could not reslove this reference" and "Namespace of type specifier in the Imports 'ModbusTCP' doesn't contain any public member or cannot be found." The dll is located in a different location on my hard drive to the project location, but this was referenced when I 'added reference'.

And when you would start your newly compiled program you can used the program you just entered in.
View 4 RepliesI have a search engine that will use a webservice to search through my database to find 3 specific things. I don't even know if it will work like this, but I have a dropdown list on my main page to select Product, Feature, Description. From what the user selects, the webservice should then go to an if statement to use the correct SELECT statement and find results for the search.
Will someone help me figure out how to fix what I've written to make it work? Please don't be too critical, I don't have a lot of experience. I have also been researching SQL Injection because I have a lot of code that is vulnerable so keep that in mind when you look at my code.
I can't get the blue squiggly lines to go away that are underneath the DropdownList1.Value instances on the WebService page.
WebService:
<WebMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()
Dim Feature As String = DropDownList1.Value
Dim Description As String = DropDownList1.Value
Dim Product As String = DropDownList1.Value

View 4 RepliesI am trying to write simple database application and try to understand ADO.net as well.say I have 2 table
1. table emp with the following field (empId, empName, empPhone, salary, deptId)
2. table dept with the following field (deptId, deptName, deptLocation, deptManager)
emp table is link to dept table via deptId.so I try to build a form with 2 data grids the top will be dept data grid and below it is emp data grid.I try to do this with out using the wizard so I know the flow and understand how to link together step by step.
in the form load section:
dim conn as new system.data.sqlclient.sqlconnection(connectionString)
dim daEmp as system.data.sqlclient.sqldataadapter
dim daDept as system.data.sqlclient.sqldataadapter
[code]....
I am kind of stuck on what to do next, I think the next step is to creat dataview from my understanding before mapping it to the datagrid, but on data grid documentation it say it can only filter datarow, it can't filter data column on the dataview.
I would like to be able to display deptName, deptLocation, no the whole column on the table to data grid, and when user select a record from dept datagrid then the employee info (empname, empphone, empsalary) is display on the second grid (again not the whole emp column table).
the user can update, add or delete emp record from employee data grid by clicing on update button, on update button callback routine I need to put something like.
daEmp.update()
from what my understanding then I need to create update, insert and delete routine and attach it to daEmp so the data grid know how to sync with sql server, so when the user say add new record since the data grid doesn't have all the field display, i.e deptId column is not on data grid, how the table know what the dept id would be? I'd like to learn without the wizard 1st since once I know how everything is link then it is easier to debug since the wizard create lots of file and it's everywhere which make it very hard to understand what is happening for someone new to vb & ado.
Okay Is there a way In vb.net to create an exe from a predefined script, for example rather than writting the methods and subs into the codedom code could I just have a textbox that I could put a script into and then have that built? (obviously omitting button presses and things.)
Im not worrying about ui's at the moment just and exe (hello world style )
Are there any tutorials for this?
