  • How create a fullscreen view of a group of controls, that belongs to a tabpage

    - by voodoomsr
    Hi all, i would like to know what is the correct way to create a fullscreen view of a tabpage control. This page has other controls, and that controls has various events that are subscribed. I was trying creating a new fullscreen form and copy all controls of the tabs to that form, but with this approach i need to resubscribe every control to the corresponding handler. If i only add the references the subscription remains but when the fullscreen form is close also the referenced copied controls are lost.

  • Changing properties of controls that were added at runtime

    - by user257412
    I have a form in which several buttons are added at runtime via a 'for' method public Form() { for (int i = 0 ... ) Button b = new Button() b.text = (string) i ; etc.. etc.. } . now i wish to change the text property of the buttons on a certain event. How can this be accomplished? I have tried a few things but none worked.. since the buttons variables are inside the method , they are not available outside. Thanks

  • Unlock a file with unlocker from a c# App?

    - by netadictos
    I am trying to unlock a file from a C# program, using unlocker. In my UI, I put a button to unlock the file the app couldn't delete. When the user pushes the button, I want unlocker (the famous app) to be opened. I have read about in the Unlocker web, and there is some explanations about the commandline to use but nothing works. I write the following code but nothing happens: "c:\Program Files\unlocker\unlocker.exe" -L "PATHFORTHEFILE.doc" Nothing happens. I have tried without parameters and with -LU. Any idea? Something more efficient than unlocker to integrate it with software?

    public void button2_Click(object sender, System.EventArgs e) { string text = textBox1.Text; Mainform = this; this.Hide(); GetSchedule myScheduleFinder = new GetSchedule(); string result = myScheduleFinder.GetDataFromNumber(text);// says there is no definition if (!string.IsNullOrEmpty(result)) { MessageBox.Show(result); } else { MessageBox.Show("Enter A Valid ID Number!"); } } says it does not contain definition for it but on my GetSchedule .cs file i have it defined public string GetDataFromNumber(string ID)//defined here { foreach (IDnumber IDCandidateMatch in IDnumbers) { if (IDCandidateMatch.ID == ID) { StringBuilder myData = new StringBuilder(); myData.AppendLine(IDCandidateMatch.Name); myData.AppendLine(": "); myData.AppendLine(IDCandidateMatch.ID); myData.AppendLine(IDCandidateMatch.year); myData.AppendLine(IDCandidateMatch.class1); myData.AppendLine(IDCandidateMatch.class2); myData.AppendLine(IDCandidateMatch.class3); myData.AppendLine(IDCandidateMatch.class4); //return myData; return myData.ToString(); } } return ""; }

  • Global hotkey capture in VB.net

    - by ggonsalv
    I want to have my app which is minimized to capture data selected in another app's window when the hot key is pressed. My app definitely doesn't have the focus. Additionally when the hot key is pressed I want to present a fading popup (Outlook style) so my app never gets focus. At a minimum I want to capture the Window name, Process ID and the selected data. The app which has focus is not my application? I know one option is to sniff the Clipboard, but are there any other solutions. This is to audit the rate of data-entry in to another system of which I have no control. It is a mainframe emulation client program(attachmate). The plan is complete data entry in Application X. Select a certain section of the screen in App X which is proof of data entry (transaction ID). Press the Magic Hotkey, which then 'sends' the selection to my App. From System.environment or system.Threading I can find the Windows logon. Similiarly I can also capture the time. All the data will be logged to SQL. Once Complete show Outlook style pop up saying the data entry has been logged. Any thoughts.

  • Spinning a 3D model in C#

    - by icemanind
    How do I take a 3D model that I created in 3D Studio Max and put it into my Winform C# program and make it spin? I'd prefer not to use DirectX if possible. I don't want anything complex. I simply want my model to rotate along the X axis. Thats it. Thanks

  • How to correctly stop thread which is using Control.Invoke

    - by codymanix
    I tried the following (pseudocode) but I always get a deadlock when Iam trying to stop my thread. The problem is that Join() waits for the thread to complete and a pending Invoke() operation is also waiting to complete. How can I solve this? Thread workerThread = new Thread(BackupThreadRunner); volatile bool cancel; // this is the thread worker routine void BackupThreadRunner() { while (!cancel) { DoStuff(); ReportProgress(); } } // main thread void ReportProgress() { if (InvokeRequired) { Invoke(ReportProgress); } UpdateStatusBarAndStuff(); } // main thread void DoCancel() { cancel=true; workerThread.Join(); }

  • How to Get a Specific Column Value from a DataTable?

    - by peace
    I have a datatable. I need to fetch a certain column value based on the user input. For example, lets say the datatable has two columns CountryID and CountryName. I need to find CountryID in the datatable based on the user input country name. I could just open a connection with DB and run the query select countryID from Country where countryName = @userinput. Is there anyway i could do this on the datatable.

  • Differences setting content in Forms.WebBrowser control via DocumentText vs. Url

    - by jeffamaphone
    If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My question is, what's going on under the covers here that is different? I've verified in both cases that the path to the images (via RClick-View Source) is the same and that all the images do, indeed, exist. In both cases the HTML is exactly the same. Any light that could be shed on this would be appreciated. Thanks!

  • Winform not scrolling when drawing objects on it

    - by dezkev
    Hello All, C#3.0,.net framework 3.5 I am drawing ( using the draw method in the graphics class) a lot of solid rectangles on a windows form vertically. The form starts at 500 x 500 px and the rectangles are only drawn at runtime after data is downloaded from the net -and the number of rectangles depends on the download so I do not know it upfront. So only a few rectangles are drawn as the size of the form is fixed. So I googled/Binged ( lest someone suggest I do that) and found a few tips but they don't work in this case -like setting the forms AutoScroll property to true or trying double buffering.I also tried to draw on a listbox control and set it's scroll property etc...but no dice. I'm guessing there is no way to display , say 200 rectangles vertically on a windows form using draw. I need some other solution... any ideas please. Maybe a list of pictureboxes and then populate each picturebox with the solid color ? Thanks

  • Is there a non-blocking version of MessageBox.Show (or something like it)?

    - by Dan Tao
    Often you just want to notify the user that something has occurred, but there's really no need for any input from them. In this common scenario, I sometimes see code like this: MessageBox.Show("Something has occurred", "Something", MessageBoxButtons.OK); This code, as we all know, causes a little pop-up window to appear with only an OK button. Now here's the thing: this code blocks (the UI thread). But in the vast majority of cases, it seems to me, if you only have an OK button, there's very little need to block. (Isn't the purpose of blocking typically to receive some input from the user? And if the user's only choice is "OK," in this typical case, isn't blocking pretty pointless?) Obviously I could just write my own little form that does basically exactly what MessageBox.Show does, except that it returns nothing (no DialogResult) and doesn't block. But I was just wondering if something like this exists already that I didn't know about.

  • datagridview rowsremoved event gets called every time data loads

    - by Nilotpal Das
    The datagridview rowsremoved event gets called every time the data gets loaded. It also makes sense to a certain extent that every time the data loads, the existing rows are removed. so technically the event should get called. But how do i differenciate that from the actual delete button getting pressed. I don't think the key events should be used, that wouldn't be a clean approach. Any help will be most appreciated.

  • Problems with overriding OnPaint and grabbing mouse events in C# UserControl containing other controls

    - by MoreThanChaos
    I've made a control which contains few other controls like PictureBox, Label and TextBox. But I'm having two problems: 1. I tried to paint some things on top of my control and when I'm overriding OnPaint, it results that things I try to draw are under controls that my control contains. Areas on which I would like to draw intersect with controls in ways that are not easy to predict. I mean that it includes something drawn on controls inside as well as on base of control. Is there a simple way to draw something on top of all contents of my control? Setting ForeColor to Transparent isn't a solution that would help me much. 2. I have a problem with grabbing mouse click events when I place my control on a form and add click event handling. It only works when I click on an area not occupied by controls inside. I would like the whole control to react to clicks and other actions like it was one consistent control. How can I redirect/handle these clicks to make them work the way I want? Thanks in advance for any tips
