Made A Database.mdf That Contains A Table That Includes 3 Diffrent Column Names
Jan 27, 2012I have made a Database.mdf that contains a table that Includes 3 diffrent Column Names.
1:"ID" This one i set to an primary key and i have also made it automaticlly put a number in order to the list. Like 1,2,3,4,5 for each data added. Data Type for this is int.
2:"WordCombination" Were i enter my word combination that i want it to look for)
3."TypeofCombination" Were i enter what the program should add to what i typed in texbox1 if it contains the WordCombination.
I want my program to se if texbox1 contains any of those WordCombinations in my database. And if thats true, Then i want it to show whats in the TypeofCombination + the text in texbox1 in texbox2. If i enter "What do you want ?" in Textbox1 i want the program to find that "What do you want ?" contains "you want" like in ID:1 WordCombination:you want. So becuse this is ture it should enter TypeofCombination in this case "Question:" + what i entered in Textbox1 to show in Textbox2.So if i write "What do you want ?" and click start. Textbox2 should show "Question: What do you want ?" If i Write "My name is Jake" and click start. Textbox2 should show "Answer: My name is Jake".If I Write "hello you Hi there Jacob" and click start. Textbox2 should show "Greeting: hello you Hi there Jacob".And i Should be able to add and delete Word Combinations Without having to change the program.

View 5 RepliesHow To Add Column With Auto-Incremental Name To MySQL Table
Sep 8, 2011I'm using VB.net to write a MYSQL application and one feature I need to add is the ability to add a column for each week that my employees worked. For example I want the first column to be called "W1" and the next one to be "W2" and so on, right up to "W52". How would I add a column to my table and have it's name add 1 to its current value? If there wasn't any letters in the name it would be easy but I need it to have the "W" in the title as well to avoid confusion. to add the column I have this:
Alter Table Manager ADD W1 MediumINT;
I just need the part that adds an INTEGER to a VARCHAR datatype if possible... Maybe there should be some sort of data type conversion involved? Just to explain further, the black bar at the very top are the date stamps for each week, I would like to have this included in the datagridview if possible but it is not required. Under each week column the employees will be entering the percents they worked (example: 20%, or 0.20 is one day of work) I know this is an odd way of doing things but its mandatory... and i was wondering if it were possible to automate the creation of these columns rather than me having to manually enter them.

VS 2010 - Submitting HTML From Textbox Into MySQL Table
Oct 19, 2011I am having a problem with submitting html from a textbox into a mysql table. I would believe this to be due to "special characters".
The code I am using is,
vb.net
Dim html = (sdata.Text.ToString)
Console.WriteLine(updateRecord("INSERT INTO course (tittle, length, begining, price, about, table) VALUES ('" & TextBox1.Text.ToString & "','" & TextBox2.Text.ToString & "','" & TextBox3.Text.ToString & "','" & TextBox4.Text.ToString & "','" & TextBox5.Text.ToString & "','" & html & "')"))
MsgBox("Success! You have Successfully created a new course, " & TextBox1.Text.ToString)
Me.Visible = False
The error I get is:
A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll
VS 2010 Chaging Table Column Length & Comboboxs
Nov 27, 2011Is there a problem with changing the column length in table and using comboboxes that display a partial list of the records from that table.I had a column(Name) that was 18 chars long. I would then display only a subset of those names in a combobox by not listing records where a column called privileges was set to X. This and other uses of combobox worked fine till I increased the column length to 24. The combobox no longer filters on the privileges field though when I select the column priviliges after my selection it will display the value X.

The problem is that the Gridview doesn't seem to like repetitive column names and is renaming the second set of Question #s to something else.
