How would you make a text box that guessed what you were about to type?...Don't understand what I mean?...for example, look at the Google search box...when you start typing stuff there, previous searches pops up underneath right? How would you make one of those? Would you need a text box to type things in and then a list box that pops up? All the info that pops up is in a database.
View 2 RepliesI have written this code for my class. I just can't figure out what is wrong with it. What the program does is set a random number in memory then a guessing box input tells if it is too high or too low or correct. I set it up so the min and max numbers can be changed. What am I doing wrong. You don't even have to tell me the code I just want to get it working

I'm creating a number guessing game. [Code] Textbox1.text refers to the answer input by player. There are two labels for displaying the range of the answer within. Label1 and Label2 refer to the lower limit and higher limit respectively. If the input value is smaller than the answer, the label1 will show the number that input into texybox1. If the input value is larger than the answer, then vice-versa. However, the program doesn't work as my expectation. Once I input the answer, the MsgBox doesn't appear. When the input value is smaller than the answer, the label1 doesn't show the input value.

I am using VB 2005 pro and sql 2005 express.I have a form linked to a sql database. and linked a sql field to a textbox. All I get when the program is running is what is in the database displayed.
But what I would like to do is take a value from a textbox and add that to the chosen field database.
I am a beginner and looking for simple code.
The listbox is populated like something from database with 3 fields - ID, Name, Date
ID - Name
1 - John
2- Susy

I'm using a DataGridView object that i populate using a series of datagridview.columns.add("xxx") and DataGridView1.Rows.Insert(0,"xxx")
I would like to create a text box that would filter the datagridview accordingly for a given column.
example: i put 'jeremy' in my text box and it returns only the row(s) with jeremy in the 'name' column.
I can filter when I'm only checking with one textbox, but when i try to use multiple text box filters its does not work the way I want it to. I understand what is going on here but i don't know what to do to fix it. Basically I have my main form with the datagridview, there is a button on this form called filter. When the user will hit this button a small form will pop up with 5 text boxes, I want to give the user the ability to enter into any text box they wish and the datagrid view will update accordingly.The problem is when they enter into one text box it works fine, but when the try entering into a second test box the filter is only filtering from the original datatable and now the dataview.
Code:
Public Class Form2
Dim dvFilter As DataView

View 2 RepliesJust started trying to convert all my access database into Sql Server databases and also create vb .net application for them all. First problem I encountered was there doesn't seem to be anything like a continous form(I know there is a datagridview). So i thought i would create a flowlayoutpanel. Place lots of textboxes on it and fill each of textboxes with information form my dataset. now on to the problem. one of the textboxes is the item description field. This field can have one word or many words

View 3 RepliesI am quite new to visual basic and databases. Im connecting to the database using the dataset wizard in visualbasic 2008. And then dragging each text field on to the form. Everything works well, saves etc., updates ok. Until I have a multiline text box , when I try and save, Iget errors highlighting the table update code and get an error saying it cant be converted to a string. I have changed all the max text limit on the database so its not that. It works ok if I set the textbox back to a single line mode. Does these databases support multiline textboxes?

I have 10 IP address I need saved so that when the programed is closed the user doesn't have to re type them all back in. To get around this I created a database that would store the values. My table contains one Field "host" and then has all 10 IP addresses listed below that.I'm trying to figure out how to make a text box on my form look at a certain row in a SQLServer 2005 table.
For example:
txtIP1.text = Row 1 of SQL table
txtIP2.text = Row 2 of SQL table
Here is what I have in my Form load Event. This works, but again I need the second rows value to show in the second txtbox.
[Code]...
Would I be able to for example, write the contents of Textbox1 (say it's labeled First Name) and Textbox2 (Last Name) and make it write to a database. The on the next screen, form, window, whatever....have it say Hello (First and Last name that was put in on the previous screen).
View 2 RepliesI am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?
