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.
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

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

I'm positive that I'm just not putting the correct calling reference in this part:

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 created a sub in a module and it should be used from 2 or 3 forms.The calling will look like this:
"Call PasswordCheck(Me.Name)"
I tried codes like:
"My.Forms(Source).txt_Password.Text"
But it told me that it can't be indexed.
In a test project I was able to add a datasource to a form, bind it to the datagridview and manipulate it as needed. Now moving forward to the actual project, is it possible to add the datasource to a class and sort through the data for use in the class?[url]...

View 6 RepliesI need some help working out the logic when retrieving specific times from a userform I have created. In my userform, users are required to input a start and a end time in 24 hour time format. I am struggling to work out how best to analyze the selected times in order to multiply them by a set of rates, the rates are quite simple:
DayHours rate (day time is between 07:00 - 22:59)
NightHours rate (night time is between 23:00 - 06:59)
I cannot workout the logic to ascertain how many hours have been selected for which rate in an elegant manner, my best attempts so far are clunky and not quite there.
I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L
[CODE]...
Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
View 1 RepliesHow can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.
I have used cookies in ASP.NET but I am not able to find out the same concept in .NET Windows Forms (C#).
How can these issues be resolves?
I have a custom form that I use instead of msgbox for a number of reasons. The initial reason was to keep the message centered on it's parent rather than the screen. There are many articles about this but I still have not found an elegant way to get access to the Parent's properties from inside the Child without passing them in (by one way or another).
In the child form the me.parent, me.parentform are not instantiated and apparently can not be used.
The point is to have this form be totally encapsulated with the logic being self contained. This is not an MDI child, and I do not want it to be due to the limitations on MDI children.
My current workaround looks like this I use a ShowMsg Function in my MyMsgBox form which looks like this:

I am trying to pass information to parent form from modal form in vb.net winforms application.
1.) I created a copy of a form and displayed it using following code.
dim f=new frmParent()
f.show()
2.) Depending on conditions a button on frmParent opens a modal child form and asks for some informations. I used following code for that:
dim f = new ChildForm()
f.showDialog()
Both code works fine. When user press saves in child form i need to close childForm and use the user types values in parent form. I know how to close the childform but not sure how to pass info from childform to parent form.
I know this has been asked, but can someone look this over. I have been going over and over this for about 3 days now. In my main form(frmBuildings) I pass a value to frmCustomerInformation like this.[code]...

But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
