VS 2008 Cannot Read Integer As Primary Key To Save To Database
Nov 13, 2009I'm using Visual Studio 2008 and MS Access 2007.
I have linked the database to vs2008.
The first problem I have now is how to add all the data to the combobox from access 2007? [I have solved this myself accidentally.]
The second problem I have is I cannot save the primary key.
Assume that I have these:
Table name: tCustomer
Fields:
ID Datatype [Text]
[Code]....
Now, the user fills in the form. The ID cannot be edited by them where it's automatically counts the number of customer in database and give the id. For example, I already have 3 customers in the database so when I add new Customer, it will be 4 for the ID.
When I click save, it shows me the message of "Index or primary key cannot contain a Null value." I have set an input mask for my Customer. So, can I make it to save in a format like CT001, CT002, CT003 automatically?
VS 2008 - Cannot Save Textbox Data Into SQL Database
Apr 19, 2009I am currently puting together a data driven application just for fun and to get to know sql. The problem i am having is on my new customer form I cannot get the data in my text boxes to save into my database table at runtime. I simply have 4 textboxes and a save button the code for my save button is as follows:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim Connection As SqlConnection = MSDB.GetConnection
Dim mySqlCommand As SqlCommand = New SqlCommand
Connection.Open()
[Code] ....
All this does is bring up an error in runtime. How to get that to work when I press save the details in my text boxes are actually saved into my database table.

Save Video Data Into Image And Convert Into Bitmap Format
May 25, 2009I have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---
[Code] .....
The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

View 1 RepliesSave Application Data (input+output) In A New File Format In Program?
May 16, 2011I work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.

View 7 Replies.net - Using MS Access Database As A File Format For Desktop Application Needing Open / Save Type Functionality?
Oct 29, 2010This is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?
VS 2008 Save A Text File With A Certain Format
Jun 5, 2009I'm trying to save a text file with a certain format, kind of trying to create some sort of colums, so when I open it will be easier to read...If I have these four words: Calendar, Car, Time, Airplane; I would like to put them into colums...
vb.net
oWriter.WriteLine("{0,50}{1,10}", "Calendar", "Airplane")
oWriter.WriteLine("{0,50}{1,10}", "Time", "Car")
The problem:When I save it to a text file or print it, it comes out like this:Calendar AirplaneTime CarHow can I put them like "centered", so that doesn't look like that mess...?
