i have recently installed Visual Studio 2010 Professional and I am currently coding in VB. I am trying to display a bar graph (pulling from MS SQL database) for certain criteria, but I do not have a "Chart" option in my Toolbox section. I have a licensed software and do not know why the "Chart" option is not present.
View 11 RepliesI have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CallLogDataSet.CallLog' table. You can move, or remove it, as needed.
Me.CallLogTableAdapter.Fill(Me.CallLogDataSet.CallLog)

I have spent the past week trying to get my copy of Visual Studio 2010 Professional to work on my Windows 7 Professional 64-bit laptop, with no avail.
Every time I try to create a new form using Visual Basic, an error message saying that Microsoft Resource File To COFF Object Conversion Utility has stopped working, and I cannot even run the new form to see if my coding is correct.
I have managed to find that it has something to do with the cvtres.exe file, but after a solid hour of research, I have found numerous others with a similar problem, but no solutions.
I have done registry scans, reinstalled Visual Studio about 3 times and have done many other suggested fixes that have done nothing but waste my time.
I want to display a message to the user if certain criteria is not met. Example of this would be - If "B" is equal to or less than "A", I want to display a message to the user.
View 5 RepliesI have VS2005 Team Edition Database Professional installed on my laptop along with VS Team Edition Database Pro, not a problem so far. When I installed the VS2008 we were using SQL Server 2005 as your databases so when asked to the database for database projects I selected my SQL 2005 installation. Now we have moved some of your databases (all new projects) to SQL 2008. When I try and create a Database Schema compare I get an error on Field types (we decided to use Date data type for one field instead of DateTime). I have since installed SQL 2008 Express so that I can create the projects in the 2008 version of SQL Server.

In our company we are using PHP to display graph from statistics in SQL over webpage. So anywhere just access the website and input the date will display statistics over the webpage of the company.
My question now is, will VB.net can do that to link SQL and display it over the webpage? Or do I need to have special software to use?
If VB.net can do it? Is there any tutorial link you can recommend for me? Video link much better.
I would like to enquire how I would go about population a chart (bar graph) in VB 2010 Professional?
I am pulling the information from a MS SQL Database.
I'm working now at a project with another person, but every time when we want to put our projects together this process is time consuming. I worked soon with an already done SVN in a java project which.
My question is: how can I make something similar for my project? I'm programming in vb.net using visual studio 2010 professional. There is a tool already?
I have seen a similar thread. But it is not answered. The Auto uninstall tool link given in that answer is not working. I want to uninstall .Net Pro Trial and going to install express edition. can anyone please tell me the order of programs to be removed?. Or please give the link for Auto uninstall tool for .Net Pro 2010.
Note: I have some software which are based on .Net Framework. so I should not remove the Framework. Is it possible to install Express Edition without removing this Framework?.

View 2 RepliesI"m having a bit of trouble getting my pie graph to work. I'm not too sure if I should be posting here, but it's about vb so I thought it would sort of fit. I've used the chart control from the toolbox, and dragged one of those across to use. I can't get more than one item to display in the chart.

I am wondering how one would go about using the graph control to display a bar graph that shows trends from my database.They are rather easy trends.

View 2 RepliesI was wondering which way would be the easiest in VS2005 to connect to and pull data from a MS SQL database. I have already setup the database connection by choosing the datasource for a DataGridView but I'm not able to retreive any information.
The steps I have taken so far:
1. Make new form
2. Drag and drop DataGridView onto the form
3. Setup the data source and respective username password
Not sure where to go from here....
I've been trying to display some information from an Oracle Database(10G) in a VB.NET program. Some of this information is in french and I need to display the french accents correctly. The e with an accent chr(233) is my test case, and it keeps coming back as either an inverted question mark (with Ole DB), a question mark (with the System.Data.OracleClient) or an 'i' (with ODBC and DSN)..

We are writing a program that pulls a Teacher from a database, then you select the "period" 1 - 7. What is happening is if we pick period 1 on teacher john doe.

View 2 Repliesif there's a way to just display the latest Symbol when drawing a graph. My app displays "real time" data from a pointPairlist and I want one graph just to be a + mark with no trace.
Dim myCurve As LineItem = m_graphPane.AddCurve("", m_pointsList, Color.Red, SymbolType.Plus)
This will show a red line with a + with every pointpair, I just want to display the latest pointpair, as an +.
I've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers.

I am developing an application with multiple picture boxes, each displaying a line graph. I want to be able to have a label following the mousepointer showing xy coordinates of the point. I also want to allow a user to zoom in on a specific picture box by double clicking on it. The code does what I want as written (changes backcolor so I know double click event fires) except moving the position of the label to follow the mouse pointer.
However if if uncomment the line in the MouseMoved sub:
LB.Location = New Point(e.X, e.Y)
Then the label moves as desired however the double click event no longer fires.
Public Class Form1
Dim PB As New PictureBox, LB As New Label
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
