As far as I can tell, if i want to append data to a RTF from a RTB, the only way is to load the RTF into a RTB, add the next text to the RTB, and then SaveFile the RTB which overwrites the original RTF.

They are numerous examples of using SaveFileDialog mainly on simple textboxes. However, I have in my resources an Excel SpreadSheet. I want to allow the use to select the destination where he can save this spreadsheet. He is not allowed to change the name of the file in the filename. Afterwards, I want to copy the file from my resources and save it to the user's selected destination. How can I do that?

I'm currently trying to program a sudoku solver. I wrote pseudocode to establish what I'd have to do. One of the first things was to make sure each number in each of the 3 x 3 grids aren't equal to any of the others. Here is my attempt. I'm pretty sure I've gone the long way around tackling this but it was the only way I was fairly confident I knew how to do. txt1_2 means that it's the second number in the first 3 x 3 grid (from left to right). At the moment, even if I put in different numbers, it comes up with two of the 'error' message boxes. This code only focuses on the first 3 x 3 grid.

Private Sub btnSolve_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSolve.Click

I have a class exercise that I need to do by next week. The problem is that I don't know how to write it.What I have to do is write pseudocode/algorithm for a scenario.I understand that I need to use a 5 step process for it but I don't know how to turn it into pseudocode.This is the scenario (there are 3 from memory that I need to do this is just one)"you want to estimate the number of hours it will take you to complete all of the levels in a new video game based on your past perfomance with other games."
I know I need to break it down into inputs, outputs and processes? I think that's right, but I'm struggling with writing it and getting it started.I don't need to use any actual code for the exercise. I just have to do the pseudocode and a flow chart for each scenario.

GOAL: Bind nested ListViews to LINQ generated iQueryable of anonymous type. I want to use LINQ because you can use GroupBy and bind the nested ListView to the 'it' keyword.
SETUP: I have groups of sets of conditions. Each set of conditions is stored in the BillingCodes table. Each group of BillingCodes is stored in the BillingGroups table.
I have a custom object that stores the ID, Name, and NumCodes for each BillingGroup that the user has chosen.I have a collection of these objects called GroupsList that has a list of the groups that the user has chosen.
Problem 1: I can iterate through GroupsList and grab all the IDs. How do I translate the SQL 'WHERE ID IN(a string of comma delineated IDs)' for LINQ to SQL? Is that the best way to do that?
Problem 2: Once I have the list of BillingGroups I need to iterate through each group. For each group, I need to iterate through the BillingCodes. For each BillingCode I need to generate a WHERE clause that has all of the conditions in the BillingCode. I propose something like so:
for each BillingGroup in BillingGroups
for each BillingCode in BillingGroup.BillingCodes
where1 = "..."
next
next
Problem 3: Here's the part where I don't have a clue. I need to dynamically create a query in LINQ to SQL. Keep in mind that I don't know how many groups there'll be or how many codes are in each group.
There are 2 tables:
**transactions**
transaction_id
patient_id

I am using vb.net 2003 and an Access database connected via Jet 4.0 OleDb. I have identified the location of my database using a relative path with [code]My program was working fine and I began making some cosmetic changes.I thought it would be a nice touch to add a PictureBox on the first form and allow the user to select the image that he would like to see when running the program.I added a menu item to "change the picture" and on a form added an OpenFile Dialog. I added code to capture the location of the selected file and used it to identify the image to be shown.I included a table in my database to store the file name and path which is loaded when the program starts.This all worked fine. I could change from picture to picture and the image would be updated each time in the picture box and in the database. I could access the database and perform all of the functions of the program.
That is as long as the image files that I selected were located in program startup directory. If I selected an image with the openfile dialog which was located else where then I could no longer contect to the database. I receive an "unhandled exceptions error". Below is the openfle code:[code]Can anyone help me with the proper way to get set up the open file dialog so that the results do not conflict with my database connection, or re-establish the connection?[code]

I am using vb.net 2003. In my program, the user can use an openfile dialog box to locate the address of a image and use it to change the display. The name and path of the image is saved in a database. This image is then loaded upon startup. If the image is located in the start-up directory the image change and saving to the database works great. But if the image is located some where else the image change occurs, but the path of the database has changed to the location of the image. Since the database is not located there, I get an unhandle exception error. What is the code to redirect the program to my startup path?

I am unable to select a .ZIP folder with either the FolderBrowserDialog (FBD) or the OpenFileDialog (OFD). First off the FBD does not show any .ZIP folders when using it and the OFD does show .ZIP folders but I am not sure how to handle it's path. My question would be how can I handle the OFDs ".SelectedPath"??? I could easily obtain that info with the FBD "FolderBrowserDialog1.SelectedPath", but it does not allow the selection of .ZIP folders.. So now I am trying to do the same thing with the OFD but there isn't any code for obtaining the ".SelectedPath". Here's some code that shows what I am trying to do:
Private sourcePath As String
Private destPath As String
With OpenFileDialog1

How to change the database connection by using openfiledilog in windows forms? The application I need to do, need to connect to a database, each time with different path and different name to explore the opened database. All the databases to be accessed are having the same structure, but with different location (in the pc itself), different name, and with different data inside (but the database tables and relations are the same. I understand openfiledialog.filename contains the address for the clicked file, but failed to pass this information to update the Database conection with the new addrerss.

Say we have a DataGridView on the main form. I can chose to establish its properties by code or by selecting them in the Properties panel. Is there a difference between these two techniques, a loading time penalty in any of the cases especially?

Does vb 2010 have a 'REQUIRED" property or control that allow you to make a textbox a "required" field? I googled and saw something about required property in controls in toolbox but somehow I could not find it anywhere in my vb 2010 toolbox. Would it be easier to write it? Does anyone have sample code?

Which parts of C# .NET framework are actually parts of the language? There are some features of C# that require specific type (the type has to implement System.IDisposable). Other features are based on patterns (any type that has something that looks like a method called Select() with the proper signature).What is the minimum set of types that C# requires from the library (the former case above)? How does that differ from other languages like VB.NET and F#?

Ok, I don't even know if the is possible, but what I want to do is have a button that when pressed will add a new text box below each other each time it is pressed. So meaning, ther4e is text in one text box, then a button is pressed, a new textbox will appear below it and you can add text to that, and so on.
