I have a web browser control in my windows form. I am trying to automate some process in a website. During this process, the invoice pdf has been generated dynamically and shown in the web browser control. I need to save that pdf locally. Please note: there is no direct link to download the pdf. I googled a lot past couple of days and haven't found any solution yet.
View 1 RepliesI have a code that dynamically generates some pictureBox-es. What I want to do is to save them so that they will aslo appear the next time the application is opened. Also i don't want to use an external configuration file so that the controls are generated on file-read.
Also I also have some controls that are generated by the designer
I have an asp.net web forms application. In this application, students upload assignments and submit a survey along with it. For the survey, I read values from DB and dynamically generate ASP.NET Controls like radiobuttonlist, checkboxlist, textbox on the form during gridview's RowDataBound Event. I cannot do it in Page_Init method because I create only if a user click on a specific assignment which requires a survey to be submitted.
When I submit the survey form, the survey values are not saved into database. During debugging I figured it out that the values are not available in the codebehind page. The radiobuttonlist.selectedvalue returns and I get following error[code]....
How can i retrieve the HTTP Request generated by the web browser control in .net (3.5). When the user navigates to an html page it may contain images, for every image the web browser control needs to make a HTTP Request. I want to display all HTTP Requests made by the web browser control. Does the web browser control use the httpWebRequest / httpWebResponse Classes internally? if so how can i access these objects?
View 3 Repliesdynamically creating buttons with images in them and then accessing the on click event for that button. However lets say for example I have three buttons created during run time, button 1, 2 and 3 for simplicities sake. Each button needs to correspond to a value (lets say one, two and three). The problem comes in when i want to, for example, click on dynamically generated button 3 and have it display "three" in a message box. But button 2 might close the program. How can i reference an event when i don't know which button corresponds to which action..

My goal is to take some form inputs and prompt the user to download a summary of everything once a certain button is clicked. I have no need for the file once it is downloaded and so I'd like to have a solution where the data is streamed directly to the user. My current solution doesn't even prompt the user for a download. Can anyone point out what I'm doing wrong?[code]....
View 2 RepliesOn my main form I have a 9 button grid that I need to fill with a gradient colour so that it represents a "heat map" going from Green (lower left) to Red (upper right). The "heat map" needs to be generated dynamically as - if I use an pregenerated image I have noticed colour variances when working on different screens / projectors as in the app there are other dynamically generated graphics & the two sets of colours need to match.So to achieve this - on my main form I have a PictureBox that I fill with the gradient colour.On top of the PictureBox I place my grid of 9 buttons.I then hide each button & take a screenshot of what is behind it & that then becomes the background image for the button. The button is then made visible.All works fine when I am testing in on a simple form The issue is that this arrangement needs to be placed on a tab control & I'm having difficulty replicating what I could do successfully on the simple form.....
Code for the colour gradient :-
Dim A As Integer
Dim B As Integer
Dim C As Integer
Dim D As Integer

The code below loads 4 Tab Pages at runtime to a TabControl. If I have UserControls in my toolbox, I can't just drag and drop the user control onto these TabPages because they don't exist yet! How do I accomplish this dynamic loading of UserControls onto the Tab Pages as they are created?

I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
I have used the following code to generate buttons dynamically. I want to know how to code in such a way that if i click one button, there should be some change done to some other button in the same form. Since all the buttons are generated in the loop, i do not know how to call one button elsewhere in the code.

To set the scene, I have implemented a drag and drop rearrange in a FlowLayoutPanel (thanks to a few good Tutorials) which worked absolutely fine until the client decided that he needed many Panels each contained in the Tabs of a Tab Control.Ironically the FlowLayoutPanel rearrange still works if the panel is not in the Tab Page. However the moment it is it stops functioning completely.In all honesty its probably a simple issue that I'm missing but I can't seem to find an answer. I'm certain that the issue is in the following block of code, most probably in the following place:If controlcoll(i).Bounds.Contains(mouse.X - flow.Left, mouse.Y - flow.Top) Then Either that or in a property of either of the controls. [code] The Panels, Tabs and Buttons (which are what need to be rearranged) are all dynamically generated.

View 4 RepliesI'm creating a PDF file on the fly using ITextSharp and ASP.NET 1.1. My process is as follows -
Create file on server Redirect browser to newly created PDF file so it is displayed to user
What I'd like to do is delete the PDF from the server as soon it is displayed in the users browser. The PDF file is large so it is not an option to hold it in memory, an initial write to the server is required. I'm currently using a solution that periodically polls for files then deletes them, but I'd prefer a solution that deletes the file immediately after it has been downloaded to the client machine. Is there a way to do this?

I'm trying to produce a repeater showing amounts of money taken by various payment types into a table.Payment types available come from a global settings file as an array, I am creating a dataTable by looping this list and extracting sales reports (there might be a more efficient way than this loop, but this is not my concern at the minute).My question: How do I bind this to a repeater and display it when I dont necessarily know the table column namesI've tried various methods to give the table a header row and give the columns numerical names from a for > next loop, but am either getting no results, orystem.Data.DataRowView' does not contain a property with the name '7'. < or whatever numberThis is where I currently am:

Dim paymentTable As New DataTable("paymentTable")
