NumericUpDown Insertion Mark On Windows Form
Apr 10, 2012
I am using Visual Studio/VB.NET 2008 and have a NumericUpDown control on Windows Form. I am forcing user to use Up/Down buttons to change the value, preventing direct entry of a value. This is accomplished be setting the ReadOnly property to True - so far so good. Is there a way to prevent the Insertion Mark from displaying? The Insertion Mark makes it look like the value can be edited, which is not possible with ReadOnly True.

Update: (Please vote to close) This question is unresolved, and is likely a list view bug.It can be replicated by using the example code from the MSDN link below, and adding this code after the list view initialization code:
myListView.View = View.Details;
myListView.Columns.Add("Column1");
myListView.Groups.Add("group", "group");

I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.

I have eight NumericUpDown controls in my form, I call them NumericUpDown_1 thru NumericUpdown 8. I first noticed when I set a breakpoint in say NumericUpDown_1 routine and have code inside this routine to manipulate say NumericUpdown_6's value, the code would immediate jump to NumericUpdown_6 routine because the value changed. This makes sense since the handler fires due to the default handler - numericUpDown_valuechanges. But I do not want this to happen so I removed the handlers for all NumericUpdownX routines, one thru eight and instead I use "addhandler" and "removehandler" statements inside the individual routines to "mask off" this problem every time I change a numericUpDown.Value that is not in it's own routine.
My problem is this does not work. What I found is if I use removehandler numericUPDown_x.valuechange addressof numericUpdown_valuechange statement the coding would work however when I'm done in that routine I follow up with addhandler numericUpDown... statement and I'm back to the same problem. A different numericUpDown routine will fire because I changed it's value in another routine but I had the handler removed before I changed it's value so I don't understand. It's almost like it remembered that it's value changed as soon as I turned back on the handler using addhandler. I'm working with Visual Basic 2010.

imagine following situation 2 forms, one form with some buttons and another form with a RichTextBox on it, if i click on the buttons the text in the RTB changes. Now i want to mark some words in the RTB with the mouse. The form with the buttons is the active form, if i click in the RTB and try to mark something, the form gets focus and comes to the front but if i move the mouse nothing happens. I have to perform a second click at first to mark something.I already tried a lot of things like setting focus to the form if the MouseButtonDown event fires, but all of that doesn't work. The only possibility that works if i set focus to the form when ever the mouse moves over the form, but this is annoying, cause everytime i move the mouse on the form the form pops to the front.How can i manage to mark the text with one simple click? Applications like OpenOffice or Notepad++ are able to do this as well.

Been looking at this for a few hours now, is it possible to insert into the FIRST line in a rich text box? I have a simple app that regularly copies a reference file to several PCs but I need to have the success/failure and timestamp visible, so I want to insert into the top line each time - ie. in descending order.

Im confused on how to write a code on checking duplicates before insertion on vb.net. I know the sequence on how to do it but its kinda confusing when writing a code.
1.) Create a query that will check if the mobile number already exists on the database
2.) If not, insert the new data
3.) Else, a message will prompt that "You are already registered".
writing this in PHP is kinda easy for me but in vb.net.. , unfortunately, not easy.. Im still a beginner on vb.net.

I've been trying to learn enough to develop the family tree diagram and making progress.[URL]..It illustrates many of the drawing, saving, re-opening, editing, drag/drop features that the family tree diagram would need, and is a good starting point.
To adapt this for the project, after searching for snippets online, I've tried to add dynamic insertion of a label as a start (eventually, it should be a textbox that the user, in runtime, can enter text into, save, re-open, edit). But, I can't get this to work. No errors display, but I must be doing something wrong.
Here's the label code which I've so far appended at the end:

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

I have recently been working on a number of sections of code that deal with the insertion of Nullable types into a database. As I'm sure anyone who has dealt with similar code will be aware of the annoyance of constantly writing conditional logic to deal with the insertion of nulls into a database. I.e.:
MyValue.HasValue ? MyValue.Value : DBNull.Value;
If(MyValue.HasValue, MyValue.Value, DBNull.Value)
Basically I am just wondering why DBNull.Value exists and why Null simply couldn't be used?

Why is it that this VB.NET code only works for detecting flash disks?
Select Case m.WParam
Case WM_DEVICECHANGE_WPPARAMS.DBT_DEVICEARRIVAL
MsgBox("USB Inserted")[code].....
What would be the possible way to detect the insertion and removal of other USB peripherals, such as mouse and keyboard?

I am having problem with my FYP that my application is based on the detection of Insertion and Removal of a device. I am aware that this would happen using Win32_VolumeChangeEvent class or WMI. (Please notify me if I am wrong). Kindly solve this problem and send the code for Console Application in VB.NET. Please do not send code in any script language or C#. Also to get the device information.

scardgetstatuschange DOES wait(timeout is set INFINITE by -1) for card-insertion after connecting the reader-device to the pc. After a card is being insterted the first time and removed again, it won't wait any longer and returns immediately everytime;
lResult = SCardGetStatusChange(DethContext, -1, rgReaderState(0), 1)
So, scardgetstatuschange CAN work. But why only when i re-attach the cardreader-device to the pc????

I'm using parameters on a SQL stored procedure to insert a record with data entered on a website form (and on the form I'm using VB.net). As of right now, the form works perfectly; the record is inserted. However, after the user hits the submit button, everything executes and then the page will basically refresh with emtpy values in all the fields. So I want to give the user some type of SUCCESS message, assuring the user the information was successfully entered into the database. So my question is: How can I verify that the record insertion was successful? I want to do this with the ExecuteNonQuery statement, because that's what I'm using.
Code is below:
If Page.IsValid then
Dim MyConn as SQLConnection= New SQLConnection("Blah")
Dim MySQL As SQLCommand
MySQL= New SqlCommand("proc_newWebEntry", MyConn)
MySQL.CommandType = CommandType.StoredProcedure

I have dealt w/ SQL as back-end many times before, but this local CE database is driving me crazy. I have a dataset (CsDbDataSet) with my table (ServiceMonitor) all set up. I have the dataset configured for CRUD and everything looks just peachy there. The problem is that I cannot write directly to the table and have it show up. I don't get any kind of error, but when I run a SELECT statement on the table, I receive no data. Am I missing something?I am using the direct database access methods used herensert Method I am trying to use:
Dim ta As New CsDbDataSetTableAdapters.ServiceMonitorTableAdapter
ta.InsertRecord("Test", Now.ToString, "TestSvc", "TestSvcVer", "TestSvcStat", "TestNote", "TestProgram")
