VS 2010 Resizing Datagrid Properties
Jan 14, 2011
I have a datagrid and load data from a database in and can't find thesolution for a couple of propblems..
1) The columns from the DB is loaded in to the datagrid but the width of each column is very small and needs resizing to view all data everytime it loads. Can I programmically make the colums show wider annd fill the datagrid?
2) I load the columns using SELECT col1,col2,col3 from table; then load that in to the datagrid. col1 is a primary key so has to be loaded as I perform an update of edited data at the end. Can I somehow hide col1 so it does not show in the datagrid?

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

The following code was taken from a javascript script. What it's (supposedly) doing is assigning properties to the line item. A name, a relations array, rounds array (which they lost in), total wins, three tiebreaker scores, and if they had a bye. (This is for a swiss pairing algorithm.)[code]I want to do something like this in Visual Basic. I'm pulling data from a table using a OleDBReader. I want to give each item that is pulled a set of these properties. Then by some means changing them.

I am using vb 2010 and I have a question about anchor. I have two panels side by side, I anchored them both: top, left, right. But when I resize it the left panel goes behind the right panel. Isn't there a way so that when I resize, both panels grow parallel?

I have some questions formating my datagrid and its columns but unfortunately unsuccessfully. How to change the alignment of a DataGridViewTextBoxColumn? I could only set the alignment of the whole datagrid. I tried to do this by code but it didn't do anything:
datagridOnlineStores.Columns("osowner").DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight
I tried defaultcellstyle but it doesn't do anything then is there any way I could change the color of the border of the whole datagrid because it's black I don't like it.

I've set every setting I could find on the DataGridView to a specific font size however when the form it resides on loads I step through the code and put my cursor over the DataGridView1.Font.Size and it always shows 8.25 (I've set everything to 18).
What I'm trying to do is resize the DGV on load of the form to a percentage based on the size of the form relative to the size of the screen. Everything else on all of my other forms are resizing correctly but the DGV is not.
Here is the designer generated code for property reference:
vb.net
'DataGridView1
'
Me.DataGridView1.AllowUserToAddRows = False
[Code].....

Having a bit of a nightmare with my application. I have developed my application in 1366 x 768. When moving onto other resolutions, the form looks totally wrong. Is there a way to have the application force itself to open up in a box that will fit the screen?(I'm more than happy to pay someone today or tomorrow who could look at making sure that my form gracefully up / down scales). This really is pretty urgent in that respect. If you have the ability to gracefully scale a form up / down and can do so for me either today or tomorrow, let me know of your price. (Possibly a bit naughty to pop this into the forums but I am willing to pay to get this sorted asap).

I have a Form (Form1) that contains a Panel inside the form. Inside that panel I want to load another form (Form2). This all works fine, however when I resize Form1 I want Form2 to resize aswell. The panel resizes fine but Form2 will not resize. Here is the code for Form1
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
Is there some sort of setting I am missing to be able to achieve this or is it not possible?

Where is the best place to resize a control on a form when a form is resized?....I'm currently using the Form1_SizeChanged event and seems to work ok. Also is there any need to check in the forms resize event if the form is in a minimized state before resizing controls?.,.. in VB6 if you try to resize a control when the form is minimized you get an error, but I don't see that happening in BV10 Form1_SizeChanged event, does VB10 automatically ignore resizing controls when a form is minimized or something?

I am creating a simple shape editor, much like the Visual Studio form designer. You can create shapes, select them and move/resize them using drag handles just like in Visual Studio or most other applications (Visio, etc).
I have run into some problems trying to implement a MinimumSize property for the shapes.First of all, this is how I'm resizing the shapes. Each shape has a Resize method, accepting two integers (dx and dy) that represent how much the shape must resize by, and one 'HitStatus', which determines in which direction the resize must take place (for example, from the TopLeft, or Bottom, or BottomRight, etc..)
What it does basically is use a large Select Case statement for the hit status. In each case, it changes the Bounds property of the shape (which determines the location and size), so that it is resized:

I've got a data-bound data grid view and one of the fields is an image. How do I scale down the image to a reasonable thumbnail size (say, 100px wide) and adjust the height and width of that cell so that it fits the image?

2. Edit columns bound column properties

I have check the properties settings without any luck.

Is there a way to validate ALL properties in a class at once? I have a class with various validations added to property "Getter" to validate user inputs. (The problem is that all my validations only invoke if a user input something to the field that bind to the property. Any fields that user simply bypass will not get validated). Ideally I want to loop through each property and validate in a "Save()" method.

I'm working on a project where I need to information on all the monitors connected to a computer and then write a configuration file based on that. I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.

I am able to use these COM objects but i do not want to due to several problems of binary compatibility on 3rd party software upgrades. So my only option was to use reflection since late binding won't work.I have several Interops and each one of them has several Classes, i do own the dlls structure, classes and methods names and definition but i am not able to use these with reflection due to my inexperience in this field.[code]

Is there an equivalent to Java Properties in VB. A Properties file in java is a place where you can save propeties for an application. So if an application looks at a file on a server (which could change) you could save to location in a properties file the if the location changes you just change the properties file. You do not have to recompile the program.

I am creating some reports using object datasources.in my software the user can create a list of products specifying a code, the product name, the price and the vat rate (this last two attributes will be used as suggestions when the user will place the product inside an order).When a user creates an order he can place products within it by specifying for each product the quantity and he can also override the suggested price and the vat rate.So basically i have two models to represent the products:
ProductModel (used to define product name, product code and the default suggestion for price and vat rate)OrderProductModel (used to place products within an order, specify the quantity and override the default product suggestion for price and vat number)
ProductModel:
id
code
name
[code]...
(suppose orderProduct is an instance of OrderProductModel)Now the question is "how to define the report rule to access to code and name?"...I am using visual studio 2010 and by reading here:[URL]they says that the syntax: =Fields!Object.Value.attribute no longer works...

I'm fairly experienced with making user controls and have never had this happen to me before. All of my custom properties (gloss opacity, border color, header color 1 and header color 2) are all grayed out in the properties window on the form designer when I try to add my groupbox to a form.
Here's my

Ok so my boss told me that I can't use DataSet's and dataadapter and such like this because it isnt good for scalability. So, I must change the way I have my 28,000 records binded to my form. The problem is, I'm only 3 months in with VB.NET and I don't know of any other way to accomplish what I need to do. I was reading somewhere that I can use a Class as my "Order" and I can bind the variables/properties to the form and with this, I can navigate through records while having controls on each important part of the "Order". Unfortunately, I don't know what I'm doing, this is as far as [code]Any guidance as to what I am to do from here in order to pull the data from my database and bind to the property, then to a text box/combo box, and a way that I can use my binding navigator to go through the many records.
