I'm having a problem adding multiple dynamic controls. the problem is that I can add one no problem, but when I try to add more it only adds one with the label's text = the last file name in openfiledialog. [Code]
View 9 RepliesI could review that could help me create a designer view (actually similar to how Visual Studio works but more basic), I would like to be able to add controls dynamically (just panels or images), then move those around individually(drag and drop), then count them all and get an array of what I have added..[code]But I would like to get an idea how it looks if things get more complicated..I wonder, are we able to use the classes of Visual Studio's editor in some way? Or are there .NEt classses that can do this?
View 2 RepliesI have multiple user controls (the same one dynamically added to a form 4 times), and one class. I would like all of the user controls raise events in that one class. For example, if any of the user controls are clicked, I want it to send a string to the class to be processed and show a MsgBox "Control name was clicked"I am doing this as an exercise to reduce repeating the same code over and over directly in the control, and to avoid creating the class over and over to accompany each user control.
View 1 RepliesWhat to use for adding multiple attachment to a email. I'm using VB 2010.
First, I have a Form in my company web site to fill a reclamation ..... when you fill and send it, it convert the form into a PDF, save it in the client side "TEMP" and finally get the PDF and send it to a email..... that's perfectly fine. I add to the form the capability of attach multiple files with file upload to the same "TEMP" and displayed in a Grid View to remove or add files and send everything to a email, the attachment capability is working. Everything is working with the PDF not the files(attachments).
There is a way to get the multiple files from the "TEMP" folder and add it to some dynamically variable (array list, attachment collection, list collection, etc.) so all can be send to the email. I already know the way to put it into the email with the PDF.
The problem is to get the files and add it to the dynamic variable and that it work with the email. If the code is need it.
I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second
My HTML
<div id="showHere" runt="server"/>
VB
Dim thisPh As New PlaceHolder
thisPh.Controls.Add(showTable)
showHere.Controls.Add(thisPh)
Dim anotherPh As New PlaceHolder
anotherPh .Controls.Add(showTable)
showHere.Controls.Add(anotherPh)
How do I make it add repeated tables within the showHere div?
I have a picture box with a label underneath it. The text of that label changes based on events. The problem I have, is when the text changes the label is no longer centered underneath my picture box.
View 5 RepliesI have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...
My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.
I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.

In previous versions of VB, you could click on a label to gain the focus, and then type multiple of lines of text. In VB 2008, clicking on the control does not open up the control for editing. You can use the text property, but can only enter a continuous string of characters. How do you insert blank lines between paragraphs?

I'm trying to implement Bandwidth Total calculation into my little desktop monitoring program using 2 *.txt files. Everything else is working great except for the writing/reading part of it. I had put this together originally without the intention of bandwidth monitoring, but I've decided it would be a good thing to have.I want to have 2 monitoring types: Windows Session Bandwidth Total & All-Time Bandwidth Total (since the program was 1st run on the machine). The counter is on a Timer (2nd of 2), and I want it to write and add the label values each second into the file, then when Form3 is opened, to read the text file and show the results.
View 12 RepliesI have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?
I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form

What is the most powerful to change all the values "text" of the Label controls?
I have question about Label.Text.
When run the code Form1 load together with Form2.On Form2 I have Label1.I need that Label.Text flicker or blinking.
I see this all the time, even on this website (MSDN). The top text box has in gray italics, "Search MSDN with Bing". And when you click in the text box the text immediately goes away. How is this done? And can it be done easily in VB.NET applications? If it's part of the managed code properties of the text box control, I can't find it.

Ho can you make a dynamic label stay right justified, so that when the label.text is filled the text starts at the right edge of the label and fills to the left? Currently the text fills to the right from the left edge of the labels location and tends to run off the form.

How would you add Dynamic controls to your form, from an array which size may vary depending on how many controls the user has selected and has been retrieved from a database?
View 2 RepliesI am programmatically adding some custom user controls to a PlaceHolder which I have on a simple aspx page. All of the user controls Postback's work correctly except for one which has a Gridview on it.
For some reason any postback that gets fired from within this control, does not call the specified event on the first click, however all future clicks it will work fine. I have no idea why this is the case, but many solutions I have found, suggest adding an ID to the ascx User Control, however this doesn't work in my case.
I've taken a look at the source file for the page that gets generated before and after the first click, javascript used for calling the postback changes, i.e
Before first click: onclick="javascript:__doPostBack('tmpControlID$sgvPrimaryEmploymentHistory','Select$0')"
After first click:
[Code]....
Again, nothing overly complicated. The USERCONTROLNAME is just a const with the value "tmpControlID" in it.
The control that is giving me trouble is a little complicated, I was originally using a custom GridView control that we have created, but have removed it and replaced it with the standard asp one to see if the problem still occurs, and it does.
Any button, on control which fires off a postback will fail the first time, and all future click will work correctly. On the first click the Page_Load event will get called, but that is it.
