I have some code that I want to apply to many objects (Pictre Boxes) and I was unable to loop through the objects via a For loop and am currently forced to copy paste the code for each Image Box.
The Pictre Boxes are named compAlien1, compAlien2 ... compAlien9
Is there a way to do something similar to this:
For i = 1 To 10 Step 1
compAlien[i]... #code#
Next i
I have a procedure in VB.net using VS.net 2008 which will get the list of Orders and build a XML file with the list of Orders as shown in the code below: As the number of Orders is getting huge, I want to build the XML file for every 500 Orders
[Code]....
Instead of building XML for all the records I want to create XML for each 500 records. I tried the following code and it is throwing an error saying Expression is of type Orders which is not a collection type.
[Code]....
I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):
Public Class MyType
Property key As Char
Property description As String
End Class
And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:
New Dictionary(Of Char, MyType)(??)
Even if this is doable, internally it will loop through all the List items, I guess?

unfortunately searching the web i cannot find a decent example that allows me to loop through a winform to make sure comboboxes items are selected.basically what i would like to do is check the form if the comboboxes have been selected if not then highlight them yellow and set the focus on them.

so this is the problem our professor gave us. the user given a chance to log-in correctly 3 times, assuming that a user log-in his/her password incorrectly there will be a loop, counting its no. of attempts. and if it exceeds to 3, there will be a msgbox assuming "you log-in incorrectly 3 times" etc. here in my code it counts but the msgbox ("try again") shows 3 times.
I have created a customised checkbox control (only the text and border appearance has been modified), and wanted to loop through them in a User quizto see which have been checked and are correct. I have used the Tag property (set to 1 or 0) to identify incorrect answers, and tried to loop through with the following code:For Each thing As GMAW.MyCheckBox In currentParent.ActiveMdiChild.Controls
View 7 RepliesI am trying to find a way to use the UseCompatibleTextRendering properties on each control on my form. However, it does not seem to be an option when i use the following code below:
For Each ocontrol As Control In Form1.Controls
ocontrol.UseCompatibleTextRendering = True
Next
ocontrol does not seem to have that option but has all other options for the button. If i do Buttion1.UseCompatibleTextRendering = True then it works just fine.
i have a winform and i have about 30 labels and 30 picture boxes on it. What i would like to do is fill each label and picturebox with a value and image from a backend database. I could have easily done this in vb6 using control struture , for eg.
for x = 1 to 30
picturebox(x).image = value from database
label(x).caption = value from database

I did a quick net search and found this which works great for looping through all the buttons to disable them. These buttons are located right on the form.
For Each ctlControl In Form_BLAH.Controls
Select Case TypeName(ctlControl)
Case "Button"
ctlControl.Enabled = False
End Select
Next ctlControl
However...when I tried it on a form where the buttons are contained within a Table Layout Panel it does not work.

View 1 RepliesI am converting a program I wrote in VB6 to Visual Studio 2010 VB.Net and have run into a problem. I am trying to cycle through 20 form elements on a form that all have the prefix 'chkCustomerItems' and then have a number 1 to 20 behind them. I am using this with a database lookup so that it there is a database entry it then applies the database item name to the checkbox's text field and turns visibility on. Here is the code I wrote:

Well I'm working on a kind of GameGuard for my private server. Ok so, I want to loop a code, I dunno if I should use Console or Windows Form Application...I dont know how to explain but I'll try doing my best to make this understandable. Ok so I want to make something that will loop this code until the console itself is closed. This code below would simply kill the windows name "Cheat Engine" program if its opened.[code]But If I use a console application, How can I make this code loop every 5 second or so? What would I need to add in this simple code to make it loop every 5 seconds and until the console is closed?
View 5 RepliesI am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]
I know that there is a method for doing this but I can't find what that would be. In my program I am looking to allow the user to create new elements(with code behind them) by entering a certain keystroke say ctrl+v(doesn't matter) and adds a textbox

View 4 RepliesI'm currently working on binding an objects properties to fields on a Form. Whilst I have managed to get it so that I can get standard objects to bind, I am having a problem figuring out how I would go about binding an inherited object.
For example, if I had a Client class (the parent class) and then two sub-classes called CompanyClient and IndividualClient. The CompanyClient would have an extra field company name for example.The problem I'm having is that I'm not certain how to set up the binding, as if I set up the binding against the Client class then I would be missing the Company Name property for the CompanyClient, if I set up against the CompanyClient, then it wouldn't work with the IndividualClient as it doesn't have all the fields.
I know I could get around this by having different forms for each of the different Client types, but as almost all of the properties are the same I would like to avoid this if I can.I was wondering whether anyone knows how I might be able to go about doing this

View 2 RepliesI have a windows forms application built in VS2005 and migrated to VS2008 that I "inherited" that occasionally will not show some of the objects (i.e. a button or something) when a user runs it. This is sporadic and does not seem to have any notable pattern.Are there any specific types of things I should be looking for that might cause such behavior? I tried looking at available memory and hard disk space issues and that did not seem to have any bearing on the problem.

In my software course, each time we submit an assignment, we have to include a document with the starting properties of each object in a form.

It's a real pain to scroll through the properties viewer and copy and paste each customised value for 30+ objects on a form... I was wondering if there'd be an easy piece of code or way about getting an (at least partially) automated printout/view of all the properties of the objects.
Was thinking some sort of private sub I could past into the bottom of the program and run on load, that gets all objects, and outputs the non-default properties to a report or something?
