View 7 RepliesI have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read)
Dim rd As New BinaryReader(fs)
Dim convertDB As UInt16
For i = 0 To rd.BaseStream.Length

I've created a module for my website and when a button is clicked, it calls a VB sub on the server.
I need this sub to retrieve the values that were filled in on the form, but the things I need to retrieve values from are not asp controls, they are simple <input> and <select> tags.
How can I retrieve values from input on a .aspx page from VB code executed behind it?
I'm trying to create a function that will check the database and compare it with the value of my label. (Basically a Version Checker) If it is the same, then nothing is displayed, if not, then I'll disable some buttons and change another text to display something. Here's the code I have so far...
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Panel2.Visible = False
[Code].....
I'm positive that I'm just not putting the correct calling reference in this part:
If Mydata(0).Read = Label2.Text Then
I have two forms
-DoctorAppointment
-DoctorSchedule
the DoctorAppointment form has all the details about the doctor and the patient and one Schedule button which will show the DoctorSchedule form When I click on any value in the DoctorSchedule form like Monday or any other day and click on save button it opens a new DoctorAppointment form and store the Day value in the text box of the form. The old DoctorAppointment form stays as it is but the new DoctorAppointment form that appears after DoctorSchedule Save click it removes all the earlier values (doctor and patient Details) that were present on the DoctorAppointment Form.
I want that after the Save click it should not call any new form instead the Day value should come on the old form including the Doctor and Patient Details.

Im taking over a project that pulls information from a database.Currently I have everything I need except the username.The person who setup the project did it as a web project so he used the MemberShip class to create unique user keys based on the person's username.
The username is not stored anywhere in the database only these userID keys.
The client wants a desktop app that mimics the website behavior of writing to the database.
Problem:I ask the user to enter in a username at the login. The username connects to the database on the server.I have no way of grabbing any user info after this point as the primary key(USERID) is a unique key and not a username. Is there a way to convert a MemberShip ProviderUserkey into a string Username or am I screwed?

Finally got to the point of having a work webservice using php and nusoap. I can retrieve values and send. Now what I want to do retrieve multiple values into a data grid, I think. What I want to do is retrieve various messages specific to that user. At the moment I retrieve values individually but as there may be more than one result I assume the datagrid may be the way forward. Now the question is how can I retrieve this information. Currently my data returns in the following format.
name.Text = returnData.name
[EDIT: I've found the problem.] So if I have a checkedlistbox and put some random values in it, I can just retrieve the values like so:
[Code]...
I have a checked listbox that I've populated with a table that has three columns, Name, Address, Phone - and have done so successfully, but when i display the items in the listbox, i would like to retrieve additional values of the checked items other than the primary displayitem.[code]'we now have an array full of the Name column only, from our checked items 'i'd like to grab the other two as well (not to display in the listbox, but to use elsewhere as variables) 'and keep the checked listbox as a control in the above code, the fill_array variable is only populated with the items displayed in the checkedlistbox - my question is, can i keep the display item the same and pull the other two columns from the datasource, but only for the ones that make the checkeditems list?
View 5 RepliesI need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.
I have a databound combobox that contains 2 fields but obviously only 1 is displayed. My question is...how do I retrieve the field that is NOT the "Displaymember"?

I am doing invoicing using VS2008 VB. I use Crystal Reports to produce the invoice. I create an in memory dataset to pass to Crystal Reports. What I would like to do is save the dataset I sent to Crystal Reports as an audit trail of the exact invoice. It would only be retrieved in the event of a dispute concerning the original invoice. I thought of using the WriteXML, ReadXML. But that would overwrite the existing XML. Does anyone have a better way of saving the XML for future retrieval?
