Msgbox Appears Behind MDI When Using CellFormatting On Datagridview?
May 23, 2011
I have never faced this problem before, I'm working on a MDI project and I have a form with a DataGridView that uses the event CellFormatting to format the cell content, if a click on a button in the form or inside the datagridview itself to show a Msgboxit appears behind the MDI form, you must realize how frustrating should be for the user that the program does not respond because the Msgbox is behind and they don't know it.
I have a datagridview control that where I need to color the rows based on a value in one of the cells in each row. I'm using the CellFormatting event like so: [code]This works fine when the grid loads and when I scroll it, etc. But when I click on the column headers to sort the grid, e.Row Index is always zero and all of the rows get the formatting of the first row..[code]For some reason, e.RowIndex is set correctly here but not on the other methods. The only thing you have to worry about here is it can be -1. But when I tried to use other methods, including PrePaint, I had to deal with it always coming up zero on a sort. If I exclude the zero case, like I excluded the negative one case about, then the first row is always white!!! I'm not sure why this works, but it does. It also produces no flicker beyond what I got using the CellFormatting event.
In my DataGridView, there is a column for names of machines in the database and I want to count how many machines of each time I have. I have set aside 1 text box with 1 label for each time of machine and in the text box, I want to display how many machines of that type are in the DataGridView?For example, I have 50 records and 30 of those records use machine "80ER" while 12 use "90E" and 8 of them are "PM100". I'd like the 80ER text box to show 30, 90E text box to show 12, and PM100 text box to show 8.
I have a menu item that appears when right clicking over a datagridview. From their the user hovers over a menuitem and a list of other menu items appears, once again this repeats. Giving soemthing like this.
There is only to be an event (addressof) handled on the the 3rd tier. With that being said I need to grab the parent.name from FOOBAR and the parent.name of the said parent (grandparent).Here is where I am at:
If currentMouseRow >= 0 AndAlso currentMouseColumn <= 1 Then dataGridView_monitorMapping.Rows(currentMouseRow).Selected = True mainMenu.MenuItems.Add(New MenuItem("Set Monitor(s) Settings"))
[code]....
And the event handler
Public Sub updateMultiRowSettingChange(ByVal Sender As System.Object, ByVal e As System.EventArgs) 'TODO | Handle selection from right click menu. End Sub
When I set rowheadersvisible to true and run the program, the little arrow appears on the left of the datagridview and a cell is highlighted. (Accessible role is none.)
I have a datagridview which is populated with information from a database. I would like it so that when I click on one of the items in the table, the information appears in the text box, or other suitable tool.
The VB output is an EPG (electronic program guide), that has a list of programs and the channels/time etc. So when you click on the program such as 'The News,' the data from the database such as 'Description' will appear in the textbox.
I am unable to popup msgbox if count=0. It will work only if i use MsgBox(""). I am unable to understand how it has anything to do with msgbox("")
Private Sub txtstaffID_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtstaffID.TextChanged Dim conn As SqlClient.SqlConnection
[CODE]...
Both IF and Elseif code executes but the problem is the msgbox won't popup in both the cases( i.e when IF executes and when Elseif executes) unless and untill i have a msgbox("") before da.Fill(dt)
If NewEntryName.Text = "" And OpenFileDialog1.FileName = Nothing Then MsgBox("Please choose a name for your game.", vbExclamation) MsgBox("Please find your game.", vbExclamation) Else Button1.Text = NewEntryName.Text game1 = True Panel1.Visible = False End If
I want it to show the first MsgBox if the NewEntryName.text = "" and I want it to show the second MsgBox if openfiledialog1 = nothing... how do I do it?
I can't seem to get my 'Save' feature to work properly. It lets me choose save and lets me choose my desired save name but when i click on 'Save', a dialog box appears saying
"problemIllegal characters in path."
I'm not sure if it's code that i'm missing or code that shouldn't be there.
I have been searching the internet and this forum for the answer to my problem, but so far nothing is working. I want a label to appear 10 seconds after the form loads. This is one of the codes that I have tried so far [code] it doesn't work. Like this the label is visible when the form loads and then disappears, but if I switch the Label2.Visible = True & False the code doesn't work at all. It also doesn't do anything if I change the = to a less than sign.
I am currently trying to sort on a GridView after it has been populated with records from a SQL Server Express database. I click on a column to sort it and I get the following error: "DataTable must be set prior to using DataView." The entirety of my code is as follows: <script runat="server" >
I am passing the data of an element inside an xml file into a sql server table with field varchar(max). This datatype is permanent and due to business rule is not allowed to be changed.[code]Notice, there are spaces and carriage returns.When pulling these data out of the xml file, in the immediate window, I can see " attached to the text where there should be a return.The sql does not take care of these returns, so that when I show these values on the UI, I do not see the carriage returns.How do I see the text on the UI as it exacly appears in the xml file ?
I'm a normal user of to Visual Studio 2008 and very experienced with VS 2005. On 2008 when after I enter the parenthesis after the object method name I see an intellisense prompt with the parameter name defined on the method along with a := sign. What does := means and why does it show up? anyway it helps me a lot sometimes if I use same variable names on different service tiers. What does := means?
I having a problem in my website where I have 2 objects held in session, both object are structured differently and do not have any links to each other (not intentionally). Both objects however, have a collection of "Travellers". What I am trying to do is modify one collection by adding or removing "Travellers", when a finish button is clicked, the modified collection will then be saved to the other object.The problem is that for some reason when I modify one collection in one object, the modifications are also made to the collection in the other object.[code]The issue is the Travellers collection within the object "BookingContext" is being updated when I add and remove from the collection within "PersonSearchContext". It's as though there is some sort of link or pointer between them.
I am trying to automate with Coded UI . Now it runs fine but when an abrupt modal window / exception window appears , it halts and tries to act on it but this was not part of recording. I want to track when this modal window appears and then kill the AUT [ application that is being automated upon ].This will at-least prevent users from watching screen w/o any progress.
Is there any way to change the sound MessageBox makes when it appears? I've written a Hangman game that displays a message box when a player wins, loses, hits an invalid key, or presses the same key twice and it always makes the same sound.
I know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.
I tried to build my project but it failed and said the exe was already in use by another process. So I looked in the Task Manager and saw several instances of this exe and several instances of another exe that I wrote. Why wouldn't the processes be stopped after I close the programs I wrote. Is there something I can do so that the processes end after I close the program?

Is it possible to make the tab (a text 'Main Report' appears in it) invisible that appears in a CrystalReportViewer just below the Toolbar? I know it shows which section of the report is opened currently but in certain scenario I need it not to be visible.
My mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use.[code]Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)What would be causing the form to freeze on .show(),
I wanna make a group box that appears behind my labels and other controls (which I create from inside the code). I dont need the controls to be in the group control collection, I only need the box because it looks nice. Right now it appears on top of all my controls.
I have noticed that even after going to this line, it does not make the label visible. I am thinking this may be a refresh issue as the last line hit is lblIsInvalid.Visible = True. Is there any refresh property that I may not be aware of for a label control.
How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:
