Action Before Displaying The Message Box, Winforms?
Apr 11, 2011
I always useMe.Cursor = Cursors.WaitCursorfor a time taking functions like hitting the DB.Now if any exception occurs, I'll display the error message as:Msgbox(ex.Message)So before displaying any message, I need to reset the cursor to default.Is there a simple way to do it at in one place instead of writing it in all catch blocks.
Is there a way to inherit MessageBox class and override the functions?Other wise I need to code it in all the catch blocks or handle all the exceptions at one place which I don't want to modify the whole application now.
I need to write some fixed-width font (i.e Courier New or Consolas) text to a .net Winforms window in the Paint event - not using a label or any other winforms control - rather using a graphics object method to render the text onto the form's client area. I am having difficulty aligning text on different lines under headings even though it is fixed width font. How can I get a precise measurement of the width of a single character in the fixed-width font? How can I get 2 lines to print out aligned horizontally in successive text out calls?
For example: Heading 1 Heading 2 Short Other text A bit longer Still aligned?
I need a separate call to render each cell of text under Heading 2. For argument's sake - let's say column 1 items are printed in black and column 2 are printed in blue - we can't use the same text out call for the entire line.
I am trying to display a message box in VB.NET. This should be simple but I cannot get it to work. I have coded in VB before and used MsgBox("Message") but in VB.NET i understand its MessageBox.Show("Message") but i cannot get it to work. Its saying MessageBox is not declared but what do you declare a message box as?
I have a simple message box and it's not displaying when i run my subroutine. I debugged to verify that it's going into the code and it does; however, the message box just doesn't display and I don't know why.
here's the part of the subroutine that the message box is in: <code> If bSuccess = True Then
I am querying a db based on some conditions and then I am putting these data in a text file. This is done by a for Loop. Is it possible to have some message box telling that data1 is being copied, data2 is being copied, etc. Some kind of dynamic textbox, telling what is being done at the background.
I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification".
In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer).
So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column.
So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?
I want to create vb.net dll for exe ie displaying error in message box after installation....For example if connection file is not correct after installation then it should display in error message for that db connection is failed.....It should happened after installation....
Actually I want to display the messages shown in cmd prompt like, if i do:
Ping google.com -t
The following message will be displayed in the cmd prompt:
Reply from 74.125.235.17: bytes=32 time=133ms TTL=51 Reply from 74.125.235.17: bytes=32 time=130ms TTL=51
[code]....
I want to display the exact information into the list box of my program instantly when it is displayed in the command prompt not after whole process is completed.
As in the ping google.com -t, I want to display the each reply message instantly in the list box.
I have couple of questions with datagridview 1.How to handle the Enter-Key when the user edited the columns value.?I mean, without changing the columns values we can suppress the enter-key by following. No problem. It's working Fine.
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown If e.KeyCode = Keys.Enter Then Dim numCols As Integer = DataGridView1.ColumnCount Dim numRows As Integer = DataGridView1.RowCount
[code]....
But after if I select any one column & changed the values then if I press <Enter> it's moving to next row. But I want to move it to next column..
2. With Datagridview - I have a column for date. and it's defaut format is mm/dd/yyyy. But Iam looking to read the date by "dd/mm/yyyy" format. Also if the user feed wrong date format then it has to display my Error message. "INVALID DATE"
I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date. User can poplutes these textboxes for multiple records and hit submit button. On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table. If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label. I got all this to work, but if it throws error message all the data in the grid is wiped out.
How can i keep data in each textbox and still display the error message?

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
I have completed and distibuted a VB.net (VS 2008) winforms application to numerous users.
One user reports the following error when opening the application:
"[Application] has encountered an error and needs to close. We are sorry for the inconvenience. If you were in the middle of something, the information you were working on might be lost."
I have a solution with number of projects developed in Visual Studio 2005 and the breakpoint is not working displaying message 'the breakpoint will not be currently hit' No symbols have been loaded for this document. I have tried solutions/suggestions in the forum and none is working. I have deleted the obj and bin directories and nothing worked. Selecting the Debug Menu, Windows, Modules option I can only see the pdb files for some projects (dlls) and cannot see for the project I'm debugging.
Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim name As String Dim icn As String Dim message As String
how to create an error message by message box to tell the user to enter a number only if they key in a character value?
I MEAN AFTER THEY PRESS THE CALCULATE BUTTON
Private Sub btnCalcFat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcFat.Click Dim intFat As Integer intFat = Integer.Parse(txtFat.Text) lblResultDisplay.Text = txtFat.Text * 9 End Sub
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.
Option Strict On Imports System.Data.OleDb Public Class Form1
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 have 2 forms, 1 is for control and the other is for display. Its 2 because the 1 for display will consume the whole screen and there's no space for buttons.Im trying to control form4 using form2 or some other form, navigating a certain webpage in the process.
I have this code for the control: but it does not work, what would I do?[URL]..
This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult ViewData("message") = "Hello" Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
I know there are several ways to publish updates but I would like to know the best way to do it. What I already have configured is a shard network folder which I intend to have the program update from there. What would the best way to publish updates to the folder be?
