i have the following code that adds three text fields to my sql table.it works if i input numbers i.e the number 1 in all three feilds but as soon as i in input text i get the error Error while inserting record on table... the name "Mike" is not permitted in this context. valid expressions are constants, contact expressions, and(in come contexts variables. column names are not permitted.This has nothing to do with the way that the sql table is setup and has soemthing todo with my code.

I want to implement the auto recovery feature in my application. i.e auto recovery of data from power failure, system crash,etc. Since the program is an multiuser with different access levels to each user, I want to save the data in a file which can only be recognized by the program. I don't want to save the data in the db, as there are many modules in which this feature has to implemented, which will make me create an separate table for each module, for temporary storage.

how to code for the save button in vb.net datagrid view by using insert into sql and update sql statements (it should be able to insert & update the data grid and save the changes) when the save button is clicked .
in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

I've written a very simple program that writes a tiny "config.cfg" (text) file to the computer (using StreamWriter), and a second program that is supposed to read that data back.
Unfortunately, it appears you can't save to the same folder as your program under Win7 ("Program Files (x86)" is a restricted folder.) So instead, VB automatically saves my data to the "C:Users(myname)AppDataRoaming..." folder. This is annoying, but tolerable.
PROBLEM IS: How does my second app then FIND my data file (without doing a time-wasting drive search every time the program is run?)
My code:
' Program #1: Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click Dim FileWriter As New StreamWriter("config.cfg")

I have three tables under one database. I'm using the built-in Navigator control for now until I get this figured out, but I'm using a button command instead of the built in navigator button. I need the "Save" button to save the data in the text fill boxes to save to the corisponding table. I used the drag and drop option to drop rows from each table to the form. See code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e

I am trying to save a pic from my picturebox. I copy an image and paste it into the picturebox. I would like to save the image that I have pasted to a file.
... the value remained the same, unchanged.1 thing though, my app is started via Sub Main() in module file, instead of "Enable application framework". Does this affect the saving of Settings file?

Im trying to retrieve images from a website in my app. Im using the HttpWebRequest to get the source of the site, and then I search the string for <img src=" to get the link of the source.
The full tag is : <img src="shopimages/products/normal/WCA356.jpg" alt="12Pc Stripe Over The Knee Socks (Black/Yellow)" style="width:300px; " class="ProductFullImage"/>
Then I do my little code just to get the actual link name... In the end it will be slink = "http://www.wickedwholesale.com/shopimages/products/normal/WCA356.jpg"
If you go to the link, you will see that the image is a full size image... 300 x 716.
I've tried used the following two methods to get the image :
[Code]....
Method 1 works fine, but looks like the image is saved as a thumbnail. About 39 x 94, instead of being 300 x 716.
Method 2 just doesnt seem to be doing anything, even tho lngRetVal is 46161906918752269.
I have a project using Application Framework and then a main form which displays the main UI. There's another form I call it frmLog, which is solely used for logging any operations internal message logging. By default, I created a Global MyApplication logging object called myLogger which is an object of type frmLog. In Application_StartUp, I instantiate it by myLogger = New frmLog. On the main UI form, there's a button Show Log which does myLogger.Visible = Not myLogger.Visible.
I have a combobox which contains few objects in Items. When the user selects any item from the combobox the values from the Object member variables are stored in the textboxes on the form.The user will change the values in the textbox and then he will select another item from the combobox.
I always wondered, but is there a way to get My.Settings to save even when you move a program, such as copy it to another location? Maybe its just me but whenever I use My.Settings in an application, copying it into a different directory will reset all the settings, which kind of sucks.Is there anyway to get the values to stay in the application no matter what? If not My.Settings, than is there any way to store a value to a program so that you don't have to use external files, but so that it will remember the settings even when copied?
How can you save a user input string to a resource? I want the user name that the user enters to be saved to a resource so that another form can use it. Or if using a module would work better, how would I do that?
