Looping Through Form Controls Using UseCompatibleTextRendering?
Jun 19, 2012
I 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 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

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.

I 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:
ConnOpenClose()
Rs = New ADODB.Recordset
Sql = "SELECT * FROM CustomersItems;"
[Code]....
When it runs, I get a NullReferenceException error. This is basically the code that I used in VB6 (with some changes for .NET infrastructure).

But there is obviously an inheritance problem, since CommonDialog objects are not controls.
Is there a way for me to loop through really all the items displayed on my form?

I have 20 controls that I created on a form. the names are like btnRing1, btnRing2, btnRing3, etc.
So I have a do while loop , and I have my variables in place. One line of code is "btnRing1.Start = PlrName" So PlrName is a variable, pulling that info from a database. I don't want to list each btnRing1, 2, 3 in each block of code in my loop.
Is there a way to use the name btnRing + 1, or something like that so I don't have to list all 20 controls in my code.
I know I can dynamically build the controls, but I can only have 20, so I need to have a little control on the numbers. So I need to have the controls already built.

I'm overriding UseCompatibleTextRendering to implent my own embedded font in my application, and it works for all controls, except the listview.
Even though this property is set to True in application events, the listview still sticks to it's default font?

I have a dynamic webpage that loads a user control multiple times, including loading the user control within itself as many times as needed. Within the user control there are four controls: Title Label, Repeater, Placeholder and within Repeater a AjaxControlToolkit Rating control.
The structure can look like the following:
Webpage
Placeholder
UserControl (repeater hidden, no data)
Placeholder - [UserControl]
[code]....
how do I efficiently loop through this type of structure to find the rating controls?

I am familer with looping thru controls like so:
[Code]....
Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

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#

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.

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?

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.

I 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]

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
