Assign A Value To A Message Box For When The Default Value Displayed In The Text Box Is Unchanged?
Jan 25, 2012
How can I assign a value to a message box for when the default value displayed in the text box is unchanged. ie. If my default value is 17 and the user clicks ok without retyping a number, the Input value displayed in a textbox will be 0.
Currently I have:
Public Class Form1
Dim MyValue As Double
Private Sub But_EnterInput_Click(sender As System.Object, e As System.EventArgs) Handles But_EnterInput.Click
MyValue = CDbl(InputBox("Input a value", "Data Input", "17", 200, 400))
[code]....
This works however if the user types 17, the textbox will read 0. not what i want.
I'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?
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.

[code]...But, when someone else runs it their user name won't be the same as mine, so only people with the account name ADAM would be able to run successfully Is there a code so instead of me putting adam there is a code that will choose the user that the program is being run by?

I have written a very simple Windows Forms App. which copies files from my hard drive to my USB flash drive.The app. works ok, but while it is running (copying files) the title bar displays (not responding).I have an idea this is due to the time it takes to do a large copy.
I have two questions:First, I want to add a progress bar, as a visual indication as to how much is left to copy, but I don't know how write the code required for the progress bar when copying say: C:*.* (including all sub-directories)
Second, to stop the (not responding) message being displayed in the title bar. Would I need to run the copy as a background process? If so, how?
i have 2 forms , in the form1 i have some data excecuting ,before enters to the process am loading form2 which has a label that am sending the text i want to display ,and a picture box with gif animator picture.At the end of the process of form1 which has finished the exceting data then am closing waitingMessage box. Here is my main problem. am succesfully display the form but the gif animator is not spining ,and the text in the form and the gif animator is like a white box and no visualy displayed.I got some time on the internet to research it and most propably the problem is mostly seems to be the threads ,but i dont know how to correctly configure it,
PS . i dont want to use the data excecution in the form2 ,becuase if i doit like this ,then when ever i want to display a waiting msg for any other process i will need to implement onother form.i would like to keep it universal and calling it when ever i want and close it as my data excecutes.form1 has some proceess to do. e.g
private sub DoMyJob
WaitingMessage.show
excecuting code here... approximatly takes 10 seconds.. becuase needs to download data from internet.[code].....
I am working on an application developed in .Net with Sql server 2005.On the form there is a datagridview called 'ManualRequestDataGridView' . Within the datagridview - Edit Columns - there is a combobox called 'media expected'. On the items section - Collections I have the following list...
Firstly I apologize as my question may seems repeated to you. But I am sure the details will not. I am writing a VBScript in VB.Net to automate some operation in SAP. The script is recorded from SAP. All I need to do is to put this script under a button click event on vb.net. I have done this far. But get stuck at one point. While doing the execution of the script, SAP displays a Message Box with two button labeled "Redetermine" & "Cancel" and I have to Click on "Redetermine" button to make the script run further.
The number of appearance of this message box is not fixed. Some times it appears twice and some times more than twice. My question is "How can I detect the Message Box from my VB.Net application and automatically click on the "Redetermine" button if the message box appears"?
I have an issue with the icon displayed on the desktop. I have used the project's properties, application form and used the dropdown menu under icon to associate an Icon to the application. I have done this loads of times before and it has always worked.
I have a datagridview bound to a datatable via a dataview. The user is allowed to edit cells in the datagridview, thereby editing cells in the datatable. I recently found that if the user editted a cell, then closed the form without ever clicking on a different cell (thereby causing the current cell to commit), the change was vanishing because the editted contents of the cell were not being saved back to the datatable.
This was only happening if the user closed the form. Clicking on any other control on the form also caused the cell changes to commit. After rooting abut in the DGV properties, it appeared that all I needed to do is add the following code to the Form Closing event handler:
If Me.dgvCurrentRedds.IsCurrentCellDirty Then Me.dgvCurrentRedds.CommitEdit(DataGridViewDataErrorContexts.Commit) End If
Sure enough, this caused the change to be registered in the underlying datatable. However, it was then getting obliterated by a different process, so I went looking for the source of that problem, and eventually tracked it down to this:
While the preceding code is causing the datatable to receive the new information, the datarow that has been changed still has the status Unchanged, even though it should have the status Modified since it actually has been modified. The fact that it appears unchanged causes some other code to obliterate the change, but that's irrelevant.
The question is, why is the row status UnChanged when it certainly has been Changed, and is there any sound way to force the row status to update?
I am working in Visual Studio 2005 in Visual Basic. I have some combo boxes with the following list in the dropdown menu:Pick 1 > New CommentPick 2 > PassPick 3 > FailPick 4 > Recommend ReplacementWhen the user chooses one of the options, I only want the text after the ">" to be displayed in the combo box's text area.[code]When I run my program, it still displays "Pick 1 > New Comment" in the text part of the combo box.
I have a form with textboxes for input. I have coded the Exit button to display a message box that asks the user if they want to save any data in the textboxes before exiting the program:
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e
[code]....
The question I have if the textboxes are blank (nothing has been entered), how do I code the Exit button to close the program without displaying the message box asking the user to save the data.' Save the numbers. Call the btnSave_Click procedure.
I've got my code to delete rows out of the database when the user clicks on the Delete button in my GridView, but the GridView isn't updating to reflect the new data changes.
EDIT 1:Did some stepping through the code and found that e.CommandArgument is not getting a value in grdQuestions_RowCommand
EDIT 1 (Revised):The fact that e.CommandArgument wasn't getting a value was my mistake. I'd changed the way it's value was being assigned without removing the previous method.The code runs through grdQuestions_RowCommand and then goes into grdQuestions_RowDeleting and then executes GetModuleData.I have a feeling that to view changes to the grid, a PostBack might be required, but I've removed all DataBinding to an If Not IsPostBack Then block because the alternative caused problems with the DropDownList whose selection is used as a reference to populate the grid (ddlModules selected the Module whose Questions will display in the grid).
I add a row to the DataSet using the following code: Dim NewRow as DataRow NewRow = gds.Tables("TitleDataSet").NewRow NewRow("Title") = txtTitle.Text NewRow("Local_number") = nubLocalnumber.Value NewRow("Number_suffix") = txtNumberSuffix.Text etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L dgvTitle.AllowUserToAddrows = True but that did not have any effect.
Solved. Was missing the final command:L gds.Tables("TitleDataSet").Rows.Add(NewRow)
I am a beginner using Visual Basic 2008. I have a problem and can't figure out the code for the following. I have a form that contains two text boxes into which the user types information. When the user clicks on one of the textboxes it becomes blank and it's contents are displayed in the other text box. I seem to be using the correct codes but can't get it to work right. Does anyone know the correct code for this?
I am working with a datagridview. It is being populated from mysql table. 2 of the columns in the table are values that would be used in a combo box. ex: 1 = Cat 2 = dog. [code]...
I now need to have a drop down menu with different languages in it.the user selects a Language from the drop down menu the text of all the relevant objects changes from like a Button with pause on it in English changes to a button with 'Pausar' on in Spanish.

I made an account manager where i can store all my accounts and I want it more protected, how can I changed the displayed text in my "colPassword" in datagridview? Just like in textbox the PasswordChar, please give me sample code :)
I need to see if a webpage displayed via the vb browser contains certain words .I've tried parasing through the html but that contains too much junk html and css tags which caused problems.That was done by using property webBrowser.document.Body.InnerText.contains . Are any way to search through the actual text via the program like the control-f function on common webbrowser ?
the question says it all, doesn't it? I was just wondering if it was possible to get only the displayed lines of text in a textbox. (Such as line indexes 1-15, to give an example.)
Text displayed by the RichTextBox1 is too big. It creates vertical and horizontal scroll bars. It there any way to zoom in and out to make the text fit as one desires?
I am clueless when it comes to this, I want to read the displayed text online. My problem right now is What Im trying to read has different html codes and I cant figure out a good way to seperate the text line by line from code
