I developped a light WinForm Control that run like an ActiveX in a Web Page. No problem yet.However, when i want to access System.IO I got a Security Exception. It seems that I have to sign my assembly, so that's what I did. When my assembly is signed, my Web Browser can't show the Winform. I set IE to download any ActiveX in the Security tab ... Nothing happens. Uncheck "Sign Assembly" ... works fine ...
View 2 RepliesI've an ASP.NET application running for reporting purposes. This is done for the management. The persons on the production floor have
a windows application running. Some of them needs to view the ASP.NET reporting page. To avoid writing twice the same reporting tools
(ASP.NET and Windows application) I want to import the ASP.Net pages into a windows form. I don't want to have the ASP.NET pages running
outside the windows application.
I am using the aspnet membership features and check to make sure the user is logged in before display the page:

If
Session(

UserName.Text = Session(

Everything was working fine when I had two separate applications (two web.config files) using the same data base and the same "applicationName" in the web.config files...............

I have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.

I try to convert winform component to webform component
(Winform Component (PictureBox) to Web User Control (asp:Image)), but it fails.
Using the form view control, when I click on the edit button to modify a record. the form is in update mode. When I clcik the update button any modified data is posted, but, for some reason the name in one filed named, user_update_name, does not. The name in the field will not change unless the field was empty. For example, if test1 was the last user to modify the record and the user_update_name field was empty, the field was now say Test1. If Test2 modified the same record, Test1 name will still display in the field. The command that fires when the update button is clicked.

In the control Chart, I add few points, selected from the database:
var Diagram_1 = Razrez_D1.Series ["D1"];
sqlDA.SelectCommand.CommandType = CommandType.StoredProcedure;
sqlDA.SelectCommand.CommandText = "Razrez_D1";
sqlDA.SelectCommand.Parameters ["@ date1"]. Value = Session ["date1"]. ToString ();

sqlDA.Fill (dataSet1, "Razrez_D1");
sqlDA.SelectCommand.CommandType = CommandType.Text;
for (int i = 0; i <dataSet1.Razrez_D1.Rows.Count; i + +)
(
string name_s = dataSet1.Razrez_D1 [i]. Name.ToString ();
name_s = name_s.Substring (name_s.IndexOf ('№')). Trim ();
Diagram_1.Points.AddXY (name_s, dataSet1.Razrez_D1 [i]. Count);
Diagram_1.Points [i]. BorderColor = System.Drawing.Color.Black;;
Diagram_1.Points [i]. BorderWidth = 1;
if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Red;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> = 4 & & Convert.ToInt32
(dataSet1.Razrez_D1 [i]. count) <= 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Yellow;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <4)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Green;
)
)
The problem is that the points on the X axis are signed that way: first is not signed, second is signed, third is not signed etc How can I sigh all points?
I'd like to add a typical 'Signed in as' bar, cf this site.Since it's 'common', first thought is: master page.However any controls designed on a master page are only rendered 'in' the final page...... so you need the 'this' (Page reference) to access the control... so you can't write code 'on' a master page, whose 'this' is not a Page.HttpContext has Session, Request, etc - all useful but none with a 'Page' reference that I've noticedUpdatePanel looks neat, but I'd prefer a non-Ajax solution to learn the 'basic' way before perhaps later making it 'smarter' with Ajax.Question therefore is: how to write a script that is site-wide, for a master page, that references controls on the (rendered) master page, with or without a 'Page' reference.
View 1 RepliesI am having a folder with the name "MyPoints". I have created a new master page inside that folder.

When i put the page inside the folder "Mypoints", i can able to see the master page image.
I have a webforms project in Visual Studio 2008. In the page load I have some code like:
Label1.Text = "Hello"
Compile, run, it shows up fine.
Then I change the code to Label1.Text = "Bla Bla"
Compile, run, the label still says "Hello."
I thought maybe it was just caching or something, so I compiled and deployed the project to my server. The label STILL says "Hello" on the server. That could not caching, could it? The page address in the browser while running locally is totally different than the page address when viewing in on my server.
Someone told me to hit Control F5 in the browser, and on BOTH the server, and on my development machine, the text changed to "Bla Bla."
This only seems to be happening in one project (and so far at least, on this one page.)
What is going on here? Why just this project? I would think any change in my code, when compiled, would show up immediately.
