View 6 RepliesI have created a search form based on my SQL database to search for individual records based on 3 types of criteria. The form is up and running but I want to be able to add some more code. I have assigned Stored Procedure to each click event for each button. What I wantr to be able to do is after value is added to text box and button is clicked if there are no reults to display than a message box is displayed with adequate message detailing this. Also is it possible to add a count of records to the form. Once value has been enetered ij tyext box and stored procedure runs and fills dataset with required data can I display a box to show number of records from this search.

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

how to go about populating some text boxes with results from calculations. To be more specific, I'm trying to do some trig to calculate various parts of a ci0rcle and will be populating any two of the text boxes then click on a button to get the missing values. I was thinking along the lines of a loop until all values have been calculated.

I am doing an application where a person can enter a string in a text box. The application reverses it. That all works fine.
I am trying to set up an if statement where if nothing is entered in the box and Submit is clicked, a message box pops up and tells you that the box can't be empty. The message box pops up fine but when the user clicks on ok to close the box, another blank box pops up. How do I get rid of the blank message box?

okay so I have a simple code to generate card picks and store them in numbers except no two cards can be the same so my checkIf functions checks it against the current list. Also no four a values can be the same since there are only 4 cards of the same type in a standard deck. Now the problem I am having is that when I run my code I only get two message boxes when I believe I should be getting 30 - (15 a's and 15 b's).[code]

In Visual Basic Express, is there a way to format text in message boxes? Specifically, I want to be able to add tabs to align text on successive lines. Currently, I'm just adding a bunch of spaces, for example, see below. I'm using Visual Basic Express 2005.

I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
I understand that currently vb.net message boxes support buttons like ok,cancel,yes,no,abort,retry.but i am wondering how do i customize my own message boxes such that i can rename the yes,no buttons to any text like delete or discard.

View 3 RepliesI am working on a simple program called "Who's Connected?" where it runs a command (netstat -aon) and then displays the results in a multi-lined textbox. However, when I press the button that will run the command, it tells me that it can't convert the string to an integer or something. And when I did manage to get it to convert to an integer, it really showed an integer in the textbox instead of the connections and IP addresses. What do I do?

I'm trying to present results on an aspx web page where a store procedure parameter is defined by a dropdown list control on the page. I have followed this guide from Microsoft and have my resultset presented in a DataGrid view. But I cannot seem to adapt it to present the resultset in a chart.
As you can see from my VB code below, I thought it would simply be a case of adapting the GridView databind to a Chart. I have tried various other options, and have successfully generated my data in a chart using a hard-coded parameter in an SQL statement on the ASP page. But when it comes to using the control, I get an empty chart.
Below is what I have so far.

I'm using visual studio 2010 and sql server 2005 to store my data. I'm creating a system that will allow me to find/search for records that are stored within the database. Thing is, i have 2 separate forms for this - one is the find/search page which allows you to enter in as many fields as you want (the more you enter, the more efficient the search is) and the second one is the find/search results page which will show the results from the search.
I'm not using a datagrid as i've already created these forms myself. I'm on a tight schedule because i've spent so much time already trying to get this to work. Do i need to create another dataset and tableadapter and bind the text boxes? how will i code the find/search button so the search will be carried out and the results will appear in the other form?
