I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.
View 1 RepliesWell, in my previous thread i needed help deleting arrays, for the codes i use its here[url]...
[code]...
Well, i want to save my array to a file that will be encrypted and then i could read it, example when i have my arrays in the application and i save it, i close my application and then i open it again i would like to load all the arrays and all the items in the "DomainUpDown" with a button, which will be read from the file, but i don't want the file to be seen from the users for secure reasons, i would like it to be encrypted.
What i had in mind was saving it as ini file, encrypting the file to another extension, and encrypt it to binary, but to do that i would use the special folder in the AppData, is there a better way for me to save the arrays and encrypt it and be able to read it again and load it in my application ?
I have two tables < student > and <class> . In vb2008 i make the connection to the database, display the data in both tables, edit existing data. The problem is that when i try to insert new rows to both tables there is a problem when i try to save both tables at the same time. The save button is in the studentBindingNavigator. I connect to the db through the Add New Data Source. The message i get is Can not insert or change a record beause it requires a relevant record in table student. Does anyone know anything about it?The two tables are related to each other.

View 4 RepliesIm not too sure if this is the correct place for this question, but I couldn't find anywhere else..Heres what i want to do. I have two tables in an Access DB. TableA and TableB. Each Table has only one column called Picture, and that column is filled with the names of pictures (picture1, picture2, picture3, etc)
Thing is, that The pictures in TableA have equivalent pictures in TableB. They are not named the same, but the pictures themselves are the same i.e.: TableA Picture1 = TableB Picture3, TableA Picture2 = TableB Picture5.
What i Would like to create is a form that has two datagrids, or Listboxes populated with the data from each table. One for TableA, One for TableB. When the User selects a picture from one of these controls, The other control must show which picture the selected one corresponds to (if i select TableA Picture1, TableB Picture3 becomes selected showing that they match)
I think that most of the work will be at the actual DB, somehow linking each and every field, maybe a one to one link between fields/cells in the DB, then in VB calling that one record that was clicked on, seeing what relation it has to the other table,

I have a database created using sql server express 2008. There I have two tables called tbl1 and tbl2, which are related as tbl1.CityNumber=tbl2.CityNumber.
I have created the programme using VB 2010; there, a form has three textboxes.
Tables: tbl1,tbl2 ; (related as tbl1.CityNumber=tbl2.CityNumber)
Columns to be updated:tbl1.CityName , tbl1.CityNumber, tbl2.StreetName
TextBoxes on the VB form: txtCityName , txtCityNumber, txtStreetName

But, now the problem is, the two tables have not get updated,after going to the database in MS.SQL Server Management Studio. I think I'm very closer to have my required result. I have tried my best to track place,where I've gone wrong.I have been trying to find a method for last five days.
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:

Sub Button1_Click(ByVal

View 1 RepliesI have a piece of software that can be used either on an admin account or a standard user account of a completely stand-alone, Windows XP machine.
I have also set up some log files that the system uses when it either performs an admin function or if an error occurs. the location of these files is a C: location - not (from what I can see) associated with the admin account in any way.
When running the software from the admin machine, the log file is appending fine. When running the software from the standard user machine, the log file causes an error, suggesting that "Access to the path 'C:HNP MTWP Log FilesAdministrative ToolsAdmin.log' is denied.
This error occurs when first setting up the FileStream. Here is my code.

View 4 RepliesI have a form with 5 fields(inputs). When I entered data in the form and click submit, the data is entered into an Access 2007 Database(Table). All the set up (connection) is working because the data table is getting populated with the user info.

This is suppose to populated all the fields with information from the data base if the user exist. The search part is not working. I have no more hair to pull. :) Here is the code:

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.
Would it be possible to make a webbrowser link to the cookies and such of any windows user account no matter which windows user account you were on. So the user would use a drop down list or something then press a button and be able to switch to another user accounts internet explorer favourites, cookies, and flash cookies, rather than having to log out and then log into another user account?

View 4 RepliesI have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

View 2 RepliesI would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.
