VS 2010 Make The Text Box Entry Related To The Message Box Pop-up?
Dec 6, 2011
I'm trying to create a program for my kid cousin; It's a small learning program for him since he is just as interested in cars as I am; and a fun change of pace for me learning something I've always wanted to try!I believe I've got it all figured out; except for how to make the text box entry relate to the message box pop-up. I want it so he learns how to type/ spell/ learn about cars; and to be more of a challenge to me.Here is the program I have started; and a screen cap of what the program physically looks like.
so one of my error message in my program looks like this MessageBox.Show("You forgot to select a Location!" & ControlChars.CrLf & "You must select a workshop and location then click Add workshop button," & ControlChars.CrLf & "repeat the process few times and" & ControlChars.CrLf & "then click Calculate button to calculate the grand total", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning)and i want the texts "Add workshop" and "Calculate" bold or highlighted when the message box appears, how do i do that?
I have a Microsoft Access database that has one-to-many relationships. When I created the tables for the database, I did not enter any data into any records, as that will be done by the application user. My problems is when data is entered into the parent and child tables, the parent table data is the only one that gets saved when clicking the save button on the binding navigator.If I have the parent and child tables data entered the same way a user would prior to connecting the data source and add EndEdit() to the child table BindingSource in the BindingNavigator click event, everything works exactly the way I want it to.This application is a data entry form, so it wouldn't make sense to have to have data entered in tables prior to adding the data source to my project. What is the best way to create a data entry form with one-to-many relationships? [code]
I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?
Okay, I've got a datagridview in my WinForms app that auto-builds the column list from a datatable schema. It's working fine, except that it allows the user to enter values too long for the database field. For example, I have a "name" field that is defined in the Sql-Server database as a varchar(50). Is there any way to limit that cell (column?) so that it only accepts 50 characters? Right now it lets them enter anything and throws an exception later.
I'm trying to make a game shop.the shop has items, and you pick which item you want through a radiobutton. Then it has a textbox that asks for the quantity of how many you want. Then how click a button, and I want a message box to pop up saying "You have purchased # (whatever item)(s)" The radiobutton text has the name of the item.
To object oriented programming and programming with visual basic .net (vb 2008 express). regarding storing of information but not in a database. Someone mentioned using binary or xml serialization. So I researched that and after two long 8 hour days of messing around with binary serialization and about a dozen different code techniques i finally found one that seems to work. I created a module that serializes two variables and appends them into a file. The same module also has a sub that deserializes the information from the file and displays in a message box. If needed I'll provide the code later.
Really the problem I am having is that my message box only displays the first entry into the file and no other. So I can append any number of variables to the file but every time I call the subroutine in my module it only displays the first entry. How do you read all of the file? Also can I search the file for a particular value of a variable? The variables are codependent. The two variables are simply a date and a string representing a changing code that corresponds to that specific date. So I'd like to be able to say search for a date and retrieve both the date and the code.
However I don't have any idea how to do this. Also the messagebox.show method is probably not the best way to illustrate the information in the file but I'm still new and I'm not sure the best way to show all the info in the file. For instance if I wanted to show the entire contents or just the codes corresponding to certain dates. I know a database is probably the better answer but I've gotten this far without one, lol, I'm too stubborn to change now. Once I figure this out, I'll switch and try the same technique with a database.
i just want to ask how can i trap the deletion message appears whenever i delete one item in may data entry? im using vb2008 and sql as my database.i know the code in access. does anyone know its counterpart in vb2008? here's the code in Access 2003acDataErrContinue
Just getting introduced with visual basic so this may be a simple question or something that makes no sense. BUT, Im making a program that searches Wikipedia depending on what the user inputs into the text box. I have what they searched in my web browser save to a listbox. Im wondering if there is a way to turn this into the history, so they can click these texts in the list box and go back to those previous web pages.
im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text For Each item As Object In listarrays.Items If item.ToString = Me.TextBox1.Text Then
[code].....
use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?
Essentially all I want to do is have a user form where you enter a reference number, hit enter and it searches an excel 2010 spreadsheet for that reference number. If the reference number is found it returns the associated name which is in the cell in the column on the right. (e.g. ref = A1 & name = B1).
I have a database created using sql server express 2008. There I have two tables called tbl1 and tbl2, which are related as tbl1.CityNumber=tbl2.CityNumber.
I have created the programme using VB 2010; there, a form has three textboxes.
Tables: tbl1,tbl2 ; (related as tbl1.CityNumber=tbl2.CityNumber) Columns to be updated:tbl1.CityName , tbl1.CityNumber, tbl2.StreetName TextBoxes on the VB form: txtCityName , txtCityNumber, txtStreetName
[Code]....
But, now the problem is, the two tables have not get updated,after going to the database in MS.SQL Server Management Studio. I think I'm very closer to have my required result. I have tried my best to track place,where I've gone wrong.I have been trying to find a method for last five days.
I have DateTimePicker where user can choose a date and make entry. I then record this entry into the database. My application date shows 08-02-2012 (i.e., 08 february 2012 in DTPicker value), when I select this and insert it to my database, the MS Access takes this as August, 2 2012, and records it as the same.
I could fix this by using this code: Dim mydate As DateTime mydate = Me.dtpicker10.Value.ToShortDateString Dim output1 As String = Format(mydate, "MM-dd-yyy") and pass sql insert query using insert into table (mydate) VALUES (#" & output1 & "#)
Instead of getting the value directly from the dtpicker. This fix the issues, but when I tried to get the date out of the database to filter it between entry made in certain date, I sometimes have problem. How do I generalize this for all type of client computers where the date and time settings can be any form. What will be the best and more flawless ways of approach to target all types of clients? Am I on the right track?

This is to Clear all numbers but I don't know how to Clear just one number. for example i want to do 23 once a user clicks CE, i want to make it show 2
trying to get my hands wet on vs 2010 and i downloaded samples from ms site but when i tried to run some of the DB samples i received this sql error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) any ideas how to get around on this?
i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
I'm trying to set up Name entry in a text box, and I don't know how to make it so it is Letters only, not alphanumeric. (spaces too) How do I set up a date label for the form using the current date? On a try statement, I'm attempting to set up two different Quantity exceptions, one for radio buttons and one for quantity in a text box, is this possible or do I have to break it up into 2 statements? Or do i have to set up a numeric if statement like I'm trying to do with the name entry.
I am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult ' Return data to the client only if the format is CF_TEXT
I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).
I was able to successfully connect my database using connection string, i am having a hard time finding tutorials on how to add the items in a textbox. [code]...
I need to change the Text property in several menu entries, for example to display several of the last files that were opened in my App.
I save the names of the last files opened, in the proper sequence, in a file that is called when my App starts.
When the App starts, the names stored in the file are assigned to the menu fields, such that the user only has to click on the desired file to load.
When the user opens a file not listed, the new name is added at the beginning of the list, and the file names are re-assigned to the Text property of the menu entries.
This works fine in VB6, but when I re-assign the string in the Text property, some menu entries are updated, but some are not.
i have to make a program thats a telephone directory. All the information is in different text files. The user has to be able to delete and add people to the directory, i have made it so they can add peple no problem but im having a hard time with the code for deleting them. The questions requires that they only type in the persons name and then they are delted but in the text file they are listed as Fred,123-1234 so when they hit delete the person does not get deleted becuase it is registering there full name as Fred,123-1234 i need it so that it just sees the word Fred and deletes it heres the code. I cant figure out how to do it itried using a query but that didnt work either it just looped infinitely.

Here's a silly question. I cannot believe I've spent so much time trying to figure it out. I have a textbox where I enter numbers, such as 12, 12.3, etc. I would like this data to display as 12.0000, 12.3000, etc. My line of code looks like this:
i downloaded samples of vb 2010, i tried to run Create DB (Data Samples) but i'm receiving this error. I have MS SQL Server 2008 installed.a network-related or instance-specific error occurred while establishing to sql server. the server was not found or was not accessible.Verify that the instances name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error:40 - Could not open a connection to SQL Server)
