  • Adding a border (Fixed3D) to an existing borderless application

    - by Aphelion
    Hi there, I have an .NET application that always starts itself with its border style to 'None', as it is supposed to be an full-screen application with a fixed resolution. However, i would like to add the window border (Fixed3D) to this window when the application starts so that I am able to move it around my desktop. My first idea was to have a tray app running, monitoring event messages, and somehow change the window style when this specific application starts. However, I am not sure if this will work and how to do this. Anyone that can point me in the right direction?

  • Secure Menu Items Based on User

    - by Mike Wills
    On this winform application I am writing, I want to secure one menu item from most users. It runs a month-end and cannot be easily backed out if accidentally run. The menu option opens up a window to prompt the user for some information before processing. I don't care where exactly I do the check, but I want to be sure only certain users can run this function. A Google search (on my question title above) didn't turn up anything obvious. Can anyone point me in a direction to pick up who is signed into Windows and how to check if they are authorized?

  • C# Creating A Program That Runs In The Background?

    - by Soo
    How can I create a program that runs in the background, and can be accessed via the Windows' "Notification Area" (Where the date and time are in the lower right hand corner)? In other words, I want to be able to create a program that runs and can toggle between having a display window and not having a display window.

  • Proper Form Application Design

    - by Soo
    I'm creating a WinForm application in C# and one of its functions is displaying text in text boxes. I'm coding the logic for querying a database in a separate class and am unable to access the text box element in the class I'm creating (I'm getting a "name" does not exist in the current context error). Do I put all of my form logic into my Form1.cs file?

  • For a DataGridView, how do I get the values from each row?

    - by David L
    I am wondering what is the best way to go iterate through all the rows in a datagridview and get the values from the cells. Here is what I am thinking of doing, but I don't really like it because if I rearrange the columns then the code will also have to be changed. for (int i = 0; i < dataGridView.RowCount; i++) { string Value0 = dataGridView1.Rows[i].Cells[0]; string Value1 = dataGridView1.Rows[i].Cells[1]; string Value2 = dataGridView1.Rows[i].Cells[2]; }

  • Which substring of the string1 matches with the string2.

    - by Harikrishna
    There are two strings. String str1="Order Number Order Time Trade Number"; String str2="Order Tm"; Then I want to know that str2 matches with which substring in the str1. string regex = Regex.Escape(str2.Replace(@"\ ", @"\s*"); bool isColumnNameMatched = Regex.IsMatch(str1, regex, RegexOptions.IgnoreCase); I am using regex because "Order Tm" will also matches "Order Time".It gives bool value that matches occurred or not. Like str2="Order Tm" then it should return like in the str1,Order Time is the substring where matches is occurred.

  • Databound Label text displays old data upon save. Re-open record and data is correct?

    - by Mike Hestness
    I have a windows forms application. I have a main form and I have a button on this form to set a "Qualified" date/time stamp. I have a Databound label control that I set the value when the user clicks the button. This date/time stamp is working as far as displaying but when you click the save button it either shows blank or the previous date/time. If you then then close the record and re-open it the new date/time value is displayed so the data is getting to the database it's just not persisting in the dataset as new data?? Not sure why the databinding isn't refreshing the value. I have noticed this behavior even if I use a textbox, same thing if I do it programatically. If I manually type in a value it persists?? Here is the code I'm using in the click event of my button: string result = string.Empty; string jobOrderID = UnitOfWork.MasterDSBS.MJOBO[0].JC_IDNO.ToString(); string timeNow = DateTime.Now.ToString(); //Call Web service to make the update RadServices.Service1 rsWeb = new RadServices.Service1(); result = rsWeb.SetQualifiedDate(timeNow, jobOrderID ); //Changed the qualified label text. _btnQualify.Text = "Qualified"; rlQualifiedDate.Text = timeNow;

    First sorry for the english. I'm having an strange problem when I'm trying to save a bitmap ("Generic GDI+ error") from a picturebox in my win app, I know that this problem occurs when trying to save to a directory that has no permission, but in this case I'm trying to save it to a memoryStream. using (MemoryStream fotoStream = new MemoryStream()) { Bitmap imagen = picture1.Image as Bitmap; imagen.Save(fotoStream, imagen.RawFormat); //Error here byte[] array = fotoStream.ToArray(); fotoStream.Close(); } Any light on this?

  • Best way to handle different panels occupying same area

    - by gmnnn
    I have this application: I want to change the marked area when the user is clicked one of the navBarItems (like Microsoft OUTLOOK). I've been doing some research and a lot of people said that I can add several panels and show/hide them when user is clicked a navBarItem. But the area will contain a lot of gridviews and a lot of other controls. I don't know if I want to initialize all of them when application starts because it's gonna be hard on the cpu and memory to keep all the controls running at the same time. And I don't think it's an elegant solution for this kind of situation. But if I choose to initialize controls when user is clicked to corresponding navBarItem, it's gonna be laggy for the user. What is the best design approach for this situation? PS: I can use commercial libraries too. Thank you.

  • A Form(?) appears briefly outside of Form1 when adding a control to it

    - by ispiro
    I have a program which creates new Controls (actually - Form's with TopLevel = false) and puts them on a Panel which is on Form1. For some reason, this is usually followed by what seems like a Form appearing very briefly outside of Form1. It's hard to tell exactly what's happening because it's so brief. Perhaps it's Form1 moving there (and changing its size) and then returning. Or perhaps it's the Form that's being put on Form1 that appears there (though how could that happen at all? It's out of Form1!). I couldn't find anything in the code that might cause it, and the whole code is way too long to post here. (The relevant code is simply: MyPanel.Controls.Add(newForm);.) Is there any known bug that might cause this?

  • How could I click in a control and drag (not Drag and Drop) out of it but still follow the event as

    - by Jelly Amma
    Hello, I would like to allow the user to click within my UserControl and drag left/right to zoom in/out but I'd like the dragging not to be restricted to the actual control's boundaries. What sort of event or strategy would be the right way to track the mouse position outside the control and the form until the mouse click is released ? Thanks in advance for any help or advice.

  • I need a row Added event for a DataGridView

    - by tizzyfoe
    What i want to do is set the background of a row based on some criteria, but the datagrid will be fairly large so i don't want to have to loop over all the rows again. The rows get created me doing something like "myDataGridView.DataSource = MyDataSource, so the only way i can think to edit rows is by using an event. there is a row*s* added event, but that gives me a list of rows that i'd have to iterate over. Thanks in advance for any help.

  • C# chart control Performance with large amounts of data

    - by user3642115
    I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series. The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down. Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues. Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens. Thanks.

  • How to optimize method's that track metrics in 3rd party application?

    - by WulfgarPro
    Hi, I have two listboxes that keep updated lists of various objects roaming in a 3rd party application. When a user selects an object from a listbox, an event handler is fired, calling a method that gathers various metrics belonging to that object from the 3rd party application for displaying in a set of textboxes. This is slow! I am not sure how to optimize this functionality to facilitate greater speeds.. private void lsbUavs_SelectedIndexChanged(object sender, EventArgs e) { if (_ourSelectedUavFromListBox != null) { UtilStkScenario.ChangeUavColourOnScenario(_ourSelectedUavFromListBox.UavName, false);

From my knowledge, I cant really see any issues with the C#. Maybe it has to do with the methodology I'm using.. maybe some kind of caching mechanism is required - this is not natively available.
