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?
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:
I have a database (Seeds1) that is connected to my project. I have gone in manually and entered data in to my database which is an Access. How do I retrieve information from my database into my program.
I 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
Ive created one database Sql Server Compact Edition 2005, with one table ("Cliente") I know that I can created my database good, but i have a problem saving information since three textbox, in my table(With columns "Nombre" "Apellido" "Cliente". In my form there is a button save ("Guardar"). When I do click in my button appear the next message : "The column cannot contain null values. [ Column name = Nombre,Table name = Cliente ] " and happen the same with apellido and Id_Cliente. And this happen becouse my code cant save the information....

I need to populate values from a database(Access) in to vb.net form. after selecting a field from first form, the next form should display all the parameters used in the selected field from the data base. Also if do editing it should be updated in the database.
My code below will save records to my database as long as all the parameter have values. One of the parameter is @MI (middle initial), however, there are times that student have no middle initial so when I click my button I get error. I want to still save the record even if one of the parameter value is missing.
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 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.

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

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?
i am working with the XML.i created a new winapp,added a label to my form.then i added xml file by : Add - > New Item-> XMLFile1.xml.[code]all i want to do is to display the message present in the body part in the label present in the form1.
I 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 stored an excel file within an SQL Server Table having the corresponding column data type as varbinary (MAX) through a VB .NET windows application form. how can I retrieve and open the stored excel file for manipulation?
i have been in state of hectic for the last 2 days making lot of research and finally made this code worked it for me. My problem is that, how can i make this code retrieve the image from sql server database...use picturebox to load it in the vb.net program.
Dim myfilelocation As String = "C:myPicturesmyimage.png"
[code]....
Is it also possible to change the location of image where its getting the image. i mean, i would like to tell other computers to get their images from anywhere as long as it brings images to my server.i mean, say that comp1 which is connected to my database server for storing and retreiving information, gets his image from his location then the application sends the image to my server...the application retreives the image from the server..as simple as that.
now the remaining things are done-able but im stuck in new requirement posted by Client which he needs to upload all images from Sql Server to Oracle Database now since old application stores images Path it is kind of new story now ?(:
i tried to build sample application since am not familiar with kind of above requested modification here is my code so far to upload images

I am trying to retrieve an image from a table in sql 2005 server. The field is set to image. I am trying to put the image strait into a picture box.
Here is my code I am using: Dim strSQL As String = Nothing strSQL = "select top 1 i.image_data" & _ " from " & mdlMainLib.GetNGConfigInfo(False, False, True) & ".dbo.person as p" & _ " inner join " & mdlMainLib.GetNGConfigInfo(False, False, True) & ".dbo.images as i on p.image_id = i.image_id" & _ " where person_id = '" & sPersonID & "'" [Code] .....
On the line ME.pb1.image = image.fromstream(stream) I keep getting a "ArgumentException was unhandled, Parameter is not valid." And that all I get to go on.
Although a few people around here have said that Dates are not a huge deal that they're simply data, I always seem to get stuck on them, and my current issue is no exception. I am trying to save/retrieve data between my Access 2003 data and my VB2005 form. I have tried any number of combinations (even the forbidden Value.ToString, and having the Data Type in Access as string, and although it worked fine for saving the data, it doesn't work for loading it back into the form.). Here's my code for saving the data to the database:
