I have created program that contain listview and it's have many column, I want user can't resize column until horizontal Scroll appear... I want user only can resize same size as listview.
View 5 RepliesI have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.

How I can resize width of column to the end of the datagridview??
View 3 RepliesI am using datagridview in my windows app.Columns width is saved in sql datatable and it sets the columns after datasource is assigned Now in column width change event new values or the width are saved in the db.
MY problem is grid is showing approximate width not exact My dgv is also docked in a splitter container where splitter distance also dynamic
as every thing is dynamic but when form resizes the values of the column width changes
VB2005 - DataGridViewMaybe not a quirk, maybe more of my misunderstanding of how resizing works. But here is what i want to do. I want to display a dataset to the user in a ataGridView. By default the columns should be autosized to all cells including the headerThat's the default view but the user should be able

View 2 RepliesI have added three columns to the ListView control,
listView1.Columns.Add("id", listView1.Width / 3); listView1.Columns.Add("Name", listView1.Width / 3); listView1.Columns.Add("Address", listView1.Width / 3);
Assume the ListView1.Width is "30", then each column should be in event width of 10. Furthermore thereshould only be three columns becuase i have added only three columns. However, when i resize teh form, the listview controls shows an additional column.
How this was added? How do i fix this, so that when i add 3 columns it will have only three columns even when resized the form or not
Best way to describe this is with an example:Create a new form, stick a DataGridView on itAnchor it to top, bottom, left, rightSet AutoSizeColumnsMode to FillAdd X columns. I added 7, in a grid size of 545, 227Run your project The grid is filled with the 7 columns, column headers all displaying nicely.
Maximise the form, same thing, all looks good. Restore the form. Column 6 is no longer correctly sized. Why? And any ideas how I fix it?
What code is needed to auto-size columns to match the width of the widest text?[code]...

I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?
View 3 RepliesI'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.
I am in the process of writing an application that requires a single transaction updating several tables. The front end has a header record and several detail records. I do not maintain any type of lock on the original read. The read is performed by calling a stored procedure in an existing database to pass back the data.
When I update the data each detail record is updated individually. Is there away I can update all of the records within a single transaction? The update will be performed via a stored procedure that is stored on the server. I cannot store the code in the application as other applications will need to use the same server side code. I can handle updating a single record my issue come about when I've updated 5 records and the 6th fails, how do I rollback the 1st 5 records.
I am developing a parser application to build a call tree from DDL files that have been extracted from a database. The idea is to take a large number of these DDL files and determine exactly what calls what. To do this I am using a .NET TreeView. The final output I am working toward is something like this:
-Proc1
-Proc2
-Proc3

I'm using vb.net 2005, I've got the following code running a thread to download a file. However, the process fails sometimes when trying to read the local copy of the file. I think I may need to unlock the local file somehow but I'm not sure how to do this.[code]
View 1 Repliesi have this application, that creates various custom AppDomains, each app domain executes a assembly and its dependencies, like a plugin, a separated assembly, that manipulates database, own resources, etc.
the application runs fine for a while, but suddenly, it locks up... the process does NOT die, it just freezes, i ran a remote debugger on top of it, on the thread window i can see EVERY thread, they are with the status "running" (not "thaw") but, in the same place, not executing. i can pause and run the debug, and it remains in the same place. there are NO locks, synlocks, monitors, on the code and the code for loading the appdomains is very simple, no big deal on it. like i said, its working, but after a while, it locks up. Any ideas on this environment?
does someone have an example code for how to prevent .exe files to be started?
Something like this might work:
For Each OSKInstance As Process In Process.GetProcessesByName("OSK").ToArray
OSKInstance.Kill()
Next
But that might be resource intense as a while loop is running all the time. Is there a smarter way to lock an .exe?
How could I lock any file in my PC from others access? I am trying to lock some my video, picture, Excel and Word file in my PC by using Visual Basic. I am using Visual Studio 2008 to develop this application but I am unable to do this job. It'll be something like security utility application. Actually without me, some other people also using my computer and I am trying to lock their access in my personal file. And I wish to know the tools which I can use for this job. I am just a Beginner on this development field.

I am trying to use a transaction for the duration that the dialog is open and then commit the changes once the dialog has been ok�d or rollback'd if canceled by the user.My problem is when I use the transaction it is locking the whole of the tables that I�m using to update and insert new records too.I update the record in the first (current) table and insert a new record into the second (history) table. Obviously this is causing me problems as I only want the transaction to lock the specific records i'm updating and not allow a new insert record with my PK associated to my that I�m updating, not lock the whole of the 2 tables.This is my code[code]....

In Visual Basic 6, locking a control would prevent the user from selecting a control without greying it out like disabling it would. Is there a way of doing this in Visual Basic 2010?
View 9 RepliesSimple question. I have a log of actions that is in XML. When some action occures, the XML log is updated. I am using:Dim xmlData as XElement = XElement.Load( "DataLog.xml" )
to load the existing data. I then create a new XElement (NewData) and use:xmlData.AddFirst( NewData )Which puts the latest item at the beginning of the log. And finally, I write it out using:xmlData.Save( "DataLog.xml" )Ok, that all works fine. But there is no testing to see if anyone has (or is) updating the file ("DataLog.xml") during the process. This may result in lost data. Is there an accepted way to implement some sort of file locking structure that can be used to prevent this potential loss?
I have some code based on some previous posts that just won't work right.The code all runs without error.
-' strErrorLog holds a valid file name with full path
-' xmlNewError holds a valid xElement value
Using holdFile As New IO.FileStream(strErrorLog, IO.FileMode.OpenOrCreate, IO.FileAccess.ReadWrite, IO.FileShare.None)[code]When I step through the code, everything works.There is no error on the xmlError.Save call.However, the actual file is NOT updated.If I remove the "Using" commands and change the save to "xmlError. Save(strErrorLog)", then it writes just fine..It's got to be something really simple, but it's frustrating that I don't get an error message.But it does unlock the file..
I've stress tested the code below and it seems to work fine - what are the dangers of not locking in the simple case where there is a single thread writing and a separate thread reading a simple variable? Have a class that has a public property...

This is the situation when there is a shift change and one record is started by one person and finished by another. What one has written another can't change but must finished a record. So u must lock only the combo boxes and text boxes that are filled. This code lockes all the combo boxes and text boxes and 2 check boxes (NEZAVRSENE_INTERVENCIJE and IZMENA_RASKRSNICE) by clicking on a NEZAVRSENE_INTERVENCIJE check box. Lets say I have combo boxes 1 2 and 3 and text boxes 1 2 and 3 and I have to lock only the ones that are filled. How do I code that another check box lockes just the filled controls?

I'm currently having issues with the following scenario:
1. I will build several DLLs with "Generate XML Documentation" set.
2. The DLL and XML files are copied onto another server (the build drop).
3. The copy will fail as the XML files are being locked by other users referencing these DLLs from their open Visual Studio projects.
Note that this also occurs on a local computer; open up two Visual Studios and use reference paths to reference the Binary folders. You'll find that the refrencing instance of Visual Studio will lock up the XML files causing the first Visual Studio to have problems compiling.
1. Is this a bug in Visual Studio 2008? Why is it holding exclusive locks on these files from the other computers? Is there a fix for this?
2. Is there a way to "package" the XML file into the DLL? I've noticed a lot of other .NET DLLs in the world that include all of their comments INSIDE of the DLL. No XML files necessary. (unless they're not .NET dll's).We're doing a lot of framework development here and it's imperative to include the XML documentation... unfortunately we've had to disable it to allow new builds to trickle through.
Title says it all. I want the ToolStrips to remain on one row, and for the user to be able to rearrange on that row but not create additional rows. I tried using SetBounds on the LocationChanged event, if the user attempted to change the Y position it just sprung right back. However, this created some visual bugs, such as the mouse always jumping back to the location and the ToolStrips jumping around randomly (while dragging one, the other would hop around randomly on the bar...)
I also tried setting the MaximumSize of the toolstripcontainer panel, but it allowed the creation of a new row anyway (in which the toolstrips were hidden.) EDIT: Its been a few months, still no answers...is this even possible?
