ToolStrip On A Databound Form - Toolstrip Buttons Don't Receive Focus In The Normal Way ?
Mar 24, 2009I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.

C# - How To Serialize Only Some Properties In .Net
Mar 15, 2010This is for a web project so i have several classes that inherit from Web.UI.
I only want to serialize very particular properties (basically, only local properties)
I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't).
So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y?
i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff.

Transfer Or Serialize Assembly
Sep 4, 2009I need a way to transfer a compiled assembly from client to the server and be able to store that in the database or in a file in such a way that I can grab those bytes on the "to" side and re-load assembly. Is there a way to do it. To clarify, I have a winforms application that will generate code and compile it based on some metadata. Now I need to be able to transfer this to a web site and store it somehow, but I don't want a dll (because it can be de-compiled). I would then have a "server" program on the to side, that would load this in memory. I could just transfer encrypted source code, but I thought I could just transfer compiled assembly.

[Code]...
This is killing performance. Anything more that about 7 or 8 clones brings the app to a halt. Why would this happen? The USING block ought to ensure the MemoryString is disposed of, right? Shouldn't a new MemoryString be created each time? I would think since the same original Mode object is the source for the serialization, the MemoryString length would be the same.
Add XML Comment During Serialize/deserialize?
Mar 31, 2009I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?

Possible To Serialize A Rendered Image?
Oct 30, 2009I have a 3D Engine which renders a 3D World onto any vb.net object with an HWND(Handle) -Picturebox or Form using Direct3D.What I'd like to do is stream that image over my LAN. I know its probably a weird idea, but I have a plan.Since the image is 'rendered' onto the object, the objects 'Image' Property is null, so sending that to a byte array doesn't do any good.Now, I've tried using the picturebox.drawtobitmap function, but it is far to slow for what I'm intending.I've used several functions in the Graphics control to try and get the image data off that picturebox, but to no avail.I've even tried sampling the surface data from Direct3D but none of these objects are able to be converted to a byte array.

Serialize An Array Into Xml List?
Jul 13, 2011It is my first time trying to serialize an array into xml list. Couldn't really find a nice tutorial out there on xml.
I have

dim Value() as string= {Value1,Value2,Value3}
When the array is serialize, i guess, i want to try to get the format to look like below:

<p data="Value3">3</p>
How o it serialize into this format, and de-serialize back into an array?

Serialize And Deserialize A Form?
Aug 7, 2010How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't.

XML Serialize Friend Classes
Sep 23, 2009I have a few classes (about 15 or so) in VB.net (2005) that I would like to be able to serialize to xml. Unfortunately they are labeled as friend classes and cannot be exposed outside of the assembly.The assembly is a dll that is a com interop plugin to a CAD system. I have set all of my classes as friends so that they are not exposed outside of the assembly for 3rd party use. I am wondering if I even need to do that. Setting the class to public would allow me to serialize things. However I don't want people linking to the assembly and using the classes.Should I even worry about other programs linking to my assembly? In fact I don't think there is a large chance of this happening. I just don't like the idea of having almost all of my classes with a public scope.Is there a way to make a friend class serializable?
View 2 Replies.net - Retriggering A VB Subroutine, How To Serialize Execution?
Mar 14, 2009I have a VB.NET subroutine that is triggered by a timer. I have found that on occasion, if the routine runs for a long time, the routine will be triggered again while it is still running with unpredictable results. Is this normal? Is each copy of the routine running in its own thread? Is there a way to serialize the routines? Right now I use a Boolean that I set True on entry and False when I am done so I can check if the routine is running when I enter it, but I thought that there might be something more elegant.
