  • Import external dll based on 64bit or 32bit OS

    - by Mike_G
    I have a dll that comes in both 32bit and 64bit version. My .NET WinForm is configured for "Any CPU" and my boss will not let us have separate installs for the different OS versions. So I am wondering: if I package both dlls in the install, then is there a way to have the WinForm determine if its 64bit/32bit and load the proper dll. I found this article for determining version. But i am not sure how to inject the proper way to define the DLLImport attribute on the methods i wish to use. Any ideas?

  • Find out where something has been installed? Or if it has?

    - by Dodi300
    Hello. Does anyone know how I can get the location of a program that has been installed. My C# WinForm is meant to launch the installer for a program, mainly games, and then be able to detect where that program was installed. Or even if it was installed successfully. Would I have to look in the registery for the location of installed programs? Or is there another way? Thanks for the help!

    - by acidzombie24
    How do i set my window above all other? I need a bad but noticeable msg box that closes on its own. Msg is a dummy form which is empty. All i want is its title. The problems with the code is the window isnt created 0,0 (its just whereever windows feels like putting it). The width is correct but i notice if i click firefox or another app window my app doesnt pop up. I know it is being shown bc i can see it in the taskbar at the bottom for a brief second. So the bugs so far Doesnt go topmost if i click another app Isnt 0,0 How do i fix this? { var msg = new Msg(); msg.Text = (has ? "*" : "+") + args[0]; msg.TopMost = true; msg.Width = 2000; msg.Top = 0; msg.Left = 0; msg.Show(); System.Threading.Thread.Sleep(1000); msg.Close(); }

  • Is using a DataSet's column Expression works in background same as manual calculation?

    - by Harikrishna
    I have one datatable which is not bindided and records are coming from the file by parsing it in the datatable dynamically every time. Now there is three columns in the datatable Marks1,Marks2 and FinalMarks. And their types is decimal. Now for making addition of columns Marks1 and Marks2 's records and store it into FinalMarks column,For that what I do is : datatableResult.Columns["FinalMarks"].Expression="Marks1+Marks2"; It's works properly. It can be done in other way also is foreach (DataRow r in datatableResult.Rows) { r["FinalMarks"]=Convert.ToDecimal(r["Marks1"])+Convert.ToDecimal(r["Marks2"]); } Is first approach same as second approach in background means is both approach same or what? EDIT: I want to know that first approach works in background as second approach.

  • Multiple PictureBoxs' C#

    - by Austin Smith
    I'm having a hard time figuring this out. I know pictureBox only lets you display one image a time. I'm trying to create a pictureBox for each image in my collection. For instance if I have ten images in my List, then the method should create ten pictureBox for those respective images so each one is displayes in a pictureBox. I'm not sure which would be better a for loop or a foreach loop instead. every time the loop increments both the varaiables XCoordinate and YCoordinate which are the location of the PictireBox shoulld increase so that the PictureBox won't overlap one another in the Form. The reason for the method is that the number of images in the collection can change everytime the application will run. That's why I'm not creating them manually. So after its done all the pictures in the list should appear in a picture.Box. The box should be all the same size the only difference is the location on the form and the images inside them. Please any help and I will be grateful

  • moving image to bounce or rotate in a circle

    - by BlueMonster
    I found this small application that i've been playing around with for the past little while. I was wondering, if i wanted to simply rotate the image in a circle? or make the entire image just bounce up and down, how would i modify this program to do so? Everything i've tried will just stretch the image - even if i do get it to move to the left or to the right. Any ideas on what i can do? Code is below public partial class Form1 : Form { private int width = 15; private int height = 15; Image pic = Image.FromFile("402.png"); private Button abort = new Button(); Thread t; public Form1() { abort.Text = "Abort"; abort.Location = new Point(190, 230); abort.Click += new EventHandler(Abort_Click); Controls.Add(abort); SetStyle(ControlStyles.DoubleBuffer| ControlStyles.AllPaintingInWmPaint| ControlStyles.UserPaint, true); t = new Thread(new ThreadStart(Run)); t.Start(); } protected void Abort_Click(object sender, EventArgs e) { t.Abort(); } protected override void OnPaint( PaintEventArgs e ) { Graphics g = e.Graphics; g.DrawImage(pic, 10, 10, width, height); base.OnPaint(e); } public void Run() { while (true) { for(int i = 0; i < 200; i++) { width += 5; Invalidate(); Thread.Sleep(30); } } } }

  • Sort a DataGridView by DisplayMember

    - by Dave
    Hi, I have a DataGridView that is bound to a DataTable. In this table there are some foreign keys. I am then using the CellFormatting event to get the corresponding text from another database table for each foreign key. I want to sort the DataGridView when the user clicks the header. Automatic sorting works but is not correct as it is Sorting on the ValueMember (ForeignKey ID) and not on the DisplayMember (the text). I tried using the SortCompare event but then I read that it does not work on DataGridViews that use the DataSource property. How can this be done? Thanks

  • Change Default Winform Icon Across Entire App

    - by Kyle Gagnet
    Can I change the default icon used on a Winform? Most of my forms have their icon property set to a custom icon. For the few forms that slip through the cracks, I don't want the generic "hey look, he made this in visual studio" icon. One solution is to tediously check every one of my forms to make sure they either have a custom icon set or have ShowIcon set to False. Another solution is to have every one of my forms inherit from a base class that sets a custom icon in the constructor. Aside from those solutions, what other options do I have? EDIT: I was hoping there would be a way to replace the source of the stock icon with my own. Is it in a resource file somewhere? Or is it embedded in a .NET dll that I can't (or really, really shouldn't) modify? BOUNTY EDIT: Is there a way to accomplish this without editing or writing a single line of code? I don't care how impractical, complicated, waste-of-time the solution is... I just want to know if it's possible. I need to satisfy my curiosity.

  • What control to use

    - by Tarscher
    Hi all, I have a list of devices that I need to filter on according to options selected by the user. One such option is cooling: when the user selects cooling only the devices with cooling are shown. If cooling is not selected then all devices (with or without cooling) are shown. I wonder what kind of control I best use for this. My feeling is thata checkbox is not a good control since it represents: No cooling (unchecked) / only cooling (checked) while I want cooling and no cooling (unchecked)/ only cooling (checked). What control is best used here? Thanks.

  • C# - How to prevent fullscreen form covering the taskbar?

    - by Dodi300
    Hello. Does anyone know how I can prevent my C# winform covering/going on top of the taskbar? My form's border style has been set to "FixedToolWindow" which seems to cause this. I thought about reducing the height of the form, when the user makes the form maximized, but that wouldn't work as people may have different size taskbars. Any ideas? Thanks.

  • How do I stop the designer from filling in my properties with null values?

    - by Tim Gradwell
    When I add a control to a form, visual studio assigns various of the properties of that form a value of null in the auto-generated designer code. I don't want the designer to make the redundant assignment (the value is already null). Can anyone tell me how to prevent it? example MyControl has property public SomeClass MyProperty { get { return m_MyValue; } set { m_MyValue = value; } } designer then autogenerates the following: myControl1.MyProperty = null;

  • Why doesn't my dataset.AcceptChanges update some new rows i've added?

    - by user280139
    I have a dataset in a datagrid with some data in it. Recently I've been asked to add some data to that dataset along with some controls to save the data from. I've added a few textboxes, 1 combobox and 3 textboxes that function as viewing of some datetimepickers that I have to use for dates. I've chosen to use textboxes in combination with datetimepicker because I also need to get and set the value NULL to the database. The problem is that when i call dataset.AcceptChanges() on that dataset that is binded using databinding to those controls it doesn't update the data that's contained in those three textboxes and the combobox. All the new stuff i've added works just fine. txtDataAcordare.DataBindings.Clear(); txtDataAcordare.DataBindings.Add("Text",dtPersonal,"d_DataAcordare"); txtDataInceput.DataBindings.Clear(); txtDataInceput.DataBindings.Add("Text", dtPersonal, "d_DataInceput"); txtDataSfarsit.DataBindings.Clear(); txtDataSfarsit.DataBindings.Add("Text", dtPersonal, "d_DataSfarsit"); this is the code i use to add the databinding. I am then using the datetime picker event CloseUp() to add the date into the textbox: txtDataAcordare.Text = dtpDataAcordare.Text; txtDataAcordare.Visible = true; txtDataAcordare.BringToFront(); After all my fields are completed i call: dtPersonal.AcceptChanges(); and these three textboxes don't get saved! Help, please! dtpDataAcordare.SendToBack();

  • UI updates not happening in the expected order

    - by allonym
    I have a Panel which hosts a number of child controls in a grid layout. The child controls each consist of a Panel with a PictureBox and a Label. When one of these child controls is clicked it becomes "selected" (which basically entails changing its background to a different color) and an event is fired. In the handler for this event, an image is displayed in a PictureBox on a separate form. In code, the background of the child control is definitely changed before firing the event, but for some reason it never updates at runtime until after the image has updated in the other Form. I've tried to Invalidate() and Refresh() the child control before firing the event, without effect. Why is this happening, and what can I do to set it right?

  • 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?
