I have an initialize function that loads data into my textbox NameTextBox, and then I add an "s" to the name. I then click the Save button that executes SaveButton_Click when debugging the value for NameTextBox.Text is still the original string (FirstName) and not (FirstNames).
Page_Load(sender, e)
Info = GetMyInfo()

I use two DataGridView“s to manage my database. DataGridView2 is filled with data from a table depending on what value you select in DataGridView1. I also have a search-function so I can search for specific values in DataGridView2. In pictures below I have searched for GroupID = 1 I can also copy all the values in the DataGridView2 into the database if I want to. The data often states what kind of values to use to use during a test of a machine. Sometimes I want to copy all the parameters for one machine and use on another machine. I have added a column that is used to write down notes about the data in the table. This is the only column not copied (except the primary key column) when I press copy. Its called Tableinfo
I can then search the active table for all rows where that column is empty. When I have changed the values or just confirmed that everything is alright I have a button called "Save" that fills that column with the string "Saved" so those rows doesn“t appear next time.
Here is where the problem occurs. When I press the save button I can see that the whole column is filled with the correct value. But when i press update the first row doesnt get updated. No matter how many rows there is in the DataGridView.
If I fill in all the rows manually it works. If I press the save button and then click in the cell of the first row where is says "Saved" and then update it gets updated correctly.

I've got a page which has 5 images on, 5 FileUpload controls, 5 buttons and in the code behind 5 on click events. The page shows the images and lets users change each individual image if they'd like and it's all working well....except. When the upload is done and the new image has been uploaded to the ftp server, how do I then re-display the same page the user has just used, but this time with the new image image in place of the old? Do I need to call an instance of the page_load event again?
View 14 RepliesIf this is a stupid question, then let me know. I can't just figure it out.First of all, this is my question. How do I detect the changed value on those text boxes?I have an idea that I create a another string values that have the original values and compare them right before saving or form closing event. This sample just have 3 text boxes, but I have 50 + text boxes on my one form. I can do it that way, but that is not really smart idea.Can I use abcDB.SubmitChanges() to detect any data changes on text boxes?
Dim sqlQuery = (From obj in abcDB.HelloWorld
Select obj.Fname, obj.Lname, obj.PhoneNumber).FirstOrDefault()
me.textboxFname.text = sqlQuery.Fname

This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]

I have a toolstriptextbox and a custom context menu strip with a "Cut" menu item. When you select text in the textbox, display the context menu and select the menu item, the cut method of the textbox is being executed, the text is pushed to the clipboard, but the text is not being removed from the textbox. The code is as simple as follows.
Sub menuItemCut_Click (byval sender as object, e as eventargs) handles menuItemCut.Click
textbox.Cut()
End Sub
I have verified the event is fired, and the selected text in textbox gets sent to the clipboard. For some reason the selected text is not removed from the textbox. Has anyone ran into this issue before when working with a toolstriptextbox?

Well, what I have implemented so far is the ordinary "Save As..." feature which I made by using a common SaveFileDialog. Now it's time for the hard part.

I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.
View 2 RepliesWhen I publish my program I get no errors, and then when I install it on another machine it says it gives me the error that it can't read the txt file that it stores data in. If I hit continue it also fails to read the database. The database file is stored in the bin/debug folder and I told my program to include it when I first added the data connection. Anything I can do to have these included so my program can run on other machines?
