Locking A ToolStripContainer Panel To Only Allow For One Row Of Toolstrips

Sep 9, 2009

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?

VS 2005 Toolstripcontainer And Scrollbars?

Jun 3, 2010

I searched the forum for this and couldn't find anything. Maybe someone can help me on this.I have a child form that has a ToolStripConatiner that holds a ToolStrip, StatusStrip and a PictureBox. I need to have scrollbars when the picturebox is larger than the form. I set autoscrollbars to true on the form but after I added the toolstripcontainer, the scrollbars no longer appear.

The toolstripcontainer is not docked but is anchored to the top,left,bottom and right. I tried unanchoring from the right and bottom, but still no scrollbars.

Does anyone know of a way to make the scrollbars appear, or maybe I am doing this all wrong and can give me a clue.It all works like I want it to except the scrollbars do not appear anymore.

Toolstrips Controls Becoming Disorganized?

Nov 19, 2007

I have an application with three toolstrips in it, two in one line and the third one on the second line. One with the common items (copy, cut etc) and two more for graphics manipulation and internet. The problem is that no matter how I "localize" their position, sooner or later they became desorganized and lose their intended location. I have localize them with the left and top property as well as using New Point(x,y). I have also experimented with different choices for the Anchor property as well as setting the values for the location property in the designer. I even put the localization code in a menu item to see if I can locate them properly after the Form Load sub is finished. Locking them in place doesn't work either. Nothing works!

Basically I need the Common toolstrip to be the first one with Left = 3 and Top = 0. Graphics1 right after the Common toolstrip and with Top = 0 and Internet1 right bellow the Common toolstrip with Left = 0 and the Top right bellow the Common toolstrip (Top = 25). It seems as if the Common toolstrip gets to the proper position and right away jumps behind the Graphics1 on the first line. The Internet1 is Ok for now (it has messed up before)?

[2008] ToolStripContainer :: Check If ToolStrip Is On Horizontal Or Vertical?

Mar 13, 2009

Now, I allow the user to drag the ToolStrip to the bottom and sides of the form. But when they drag it to the sides, the ToolStripPanels become completely stretched because the text is still drawing horizontally. I know I can set the TextDirection property to make it draw vertically, but I can't figure out how to check the current position of the ToolStrip, and when to check it (which event?)

I have tried the LocationChanged event and did this:
vb.net
Private Sub ts_LocationChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

Forms :: Borders Around Toolstrips On MDI Form?

Mar 31, 2011

I have a MDI container form with menustrip, toolstrip and statusstrip on it. The backcolor of these items is black. The toolstrip and statusstrip show ugly white borders around them which I want to get rid of but there seems to be no such property like bordercolor or anything where I could change them.

VS 2010 Best Containers For Some Toolstrips And A Picturebox

Apr 14, 2012

Been doing web development for the past 2 years - so I'm a little rusty (and I just switched to VS 2010 from 2008 so maybe something new is available)... I have 4 toolstrips floated to the top of a form. And I have a picturebox below - filling the whole form. Unfortunately the picturebox is "behind" the toolstrips. I want to split the form so that the top of the form holds the 4 toolstrips and the picturebox appears below them.

What would be the proper container to put this mess into so that autosizing is the easiest? The toolstrips will most likely be "turned off and on" during the running of the app.

Make Docking Forms & Auto Expanding Toolstrips?

Jul 1, 2009

The First Question is not that important but you know that when you click on 'Favorites' in IE 8 a form thing comes up? Well I've been trying to do that for a long time but I can't figure out how. 2: In IE8 when you expand the window and collapse the window, the toolbars expand and collapse as well. How do I make my tool bars in my Web Browser do that. 3: I actually have a third question and that's, How do you make a horizantal scroll bar on your web browser control. (just like in Internet Explorer.)

VS 2008 Adding ToolStrips To A Container During Design-time (via Collection Editor)

Oct 28, 2009

I am trying to extend the functionality of the ToolStripPanel control (which is a panel hosting ToolStrips that can be moved during design-time, as I'm sure you know).One thing I wanted to add was a 'ToolStrips' property, which would be a collection of ToolStrips the user can edit via the collection editor in the designer. So instead of manually placing ToolStrips on the ToolStripPanel via the toolbox, the user can just use the property to add/remove (or even edit) them. This is of course similar to how you add/remove/edit TabPages in a TabControl.So, I came up with this code, which I have used successfully in the past for other controls:

Public Class cToolStripPanel
Inherits ToolStripPanel
Private _ToolStrips As New ToolStripCollection(Me)[CODE]....

The cToolStripPanel control inherits the ToolStripPanel control and adds the ToolStrips property, which is of type ToolStripCollection. That class, in turn, inherits the Collection(Of ToolStrip). In the InsertItem method, I add the 'item' ToolStrip to the cToolStripPanel. Of course I also need to override the RemoveItem / ClearItems methods but that's for another time.I am 100% sure that this code should works, at least for other controls. If you replace ToolStrip with Button (for example), I can add buttons via the property during design-time just fine, exactly the way I want it.But it seems that ToolStrips are special. When I try to Add a toolstrip (via the collection editor Add button), a null reference exception occurs. I've been trying to debug this all day and I've finally come up with a possible candidate for the problem... (I've actually used design-time debugging for the first time ever, which was pretty cool, and which showed me that the InsertItem method is not run!)

I think the problem is that the collection editor cannot create a new instance of the ToolStrip class. I can remember when trying to inherit from the ToolStrip, I was forced to add a constructor, because the ToolStrip "has more than one constructor that can be called with no arguments".Perhaps this is causing my problem? Do I (and if yes, how?) have to somehow control the creation of a new instance of the ToolStrip? Or am I completely off track and that is not what is causing the problem? I'm sure that it's a problem with the ToolStrip class, since I can use the exact same method with other controls just fine. It's only when I change the type to ToolStrip that it starts getting angry at me....

Asp.net - Controls (buttons) Be Set In A ModalPopup Extender Panel That Do Not Close The Panel?

Apr 21, 2009

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.

However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).

The user is supposed to be able to add an email or click on a search button to populate a list to choose from.

The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.

Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.

So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).

Panel Within A Panel, Overlapping Borders Show As Bold And Indented?

May 8, 2009

I'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
Inherits System.Windows.Forms.Form[code].....

What I'd like to see is just a single line, not bold or indented, where the two panels borders are equal.Is there a property or custom paint technique I could use to achieve this behavior?

ADO.NET And SQL Locking?

Sep 23, 2010

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.

Autoscroll X.panel According To T.panel's Scroll Position

Mar 19, 2009

This is for a mapping/plotting program.

t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.

Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

C# - Application Suddenly Locking Up

Jan 10, 2012

i 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?

Something like this might work:

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?

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]....

Writing To XML Log - File Locking?

Oct 15, 2009

Simple 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?

Writing To XML With File Locking

Nov 2, 2009

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..
