  • Windows theme affecting ListView header

    - by LihO
    I've created new Windows Forms Application (C#) with one simple form containing ListView. Then I changed the View Property to Details and increased the size of the font used in this ListView and here's the result: This is how it looks on Windows XP with Windows Classic theme: and here's the result with Windows XP theme: Creating the same Windows Forms Application in Visual C++ instead of C# yields same result. EDIT : Thanks to Kamil Lach, we already know that Visual Styles is what makes the appearance of ListView change. This can be avoided either by removing Application.EnableVisualStyles() call or by changing the Application.VisualStyleState. Both of these solutions yield the following result: This looks fine, but this change affects the appearance of other controls which is not good. I'd like my ListView to be the only control that is not affected by Visual Styles. I've also found similar questions that try to deal with it: Can you turn off visual styles/theming for just a single windows control? How do I disable visual styles for just one control, and not its children? Unfortunately, none of mentioned solutions works. Any C# solution that would make the ListView header have the correct height would be appreciated.

  • Visual C# | Capturing data from a window in a closed-source third-party Win32 application

    - by Zach Albia
    I'm planning on creating a C# Windows Forms app as an extension for a third-party Win32 application but I'm stumped as to how to do this right now. The farthest I've gotten is knowing it involves Win32 Hooking and that there's this open source project called EasyHook that's supposed to allow me to do this. I'd like to know how I can get the text from a textbox or some other data from a control in a third-party Win32 application. The text/data in a control is to be captured from the external application's running window the moment the user presses a button. I guess the question can be summed up as follows: How do you determine the event to hook to when the user clicks a certain button? How do you get the value displayed by a Win32 control at the time the button is clicked?

  • Iterating through tooltips

    - by icemanind
    Guys, I have a windows form with a panel control and inside the panel control are several other controls with a System.Windows.Forms.Tooltip attached to them. How can I iterate through each tooltip and set the Active property of the tooltip to false? Tooltips, unlike other controls, are not actually controls. So I had this: foreach (System.Windows.Forms.Control ctrl in this.pnlControl.Controls) { if (ctrl.Name.StartsWith("tt")) // since all my tooltip names start with 'tt' { System.Windows.Forms.ToolTip TipControl=(System.Windows.Forms.ToolTip)ctrl; TipControl.Active=false; } } This does not work though. It gets an error because the ToolTip control is not inherited from System.Windows.Forms.Control. Any ideas?

  • IS there a simple way to remove Alt-Character shortcuts at runtime

    - by Dan Neely
    I have a dialog with a number of Alt-Letter shortcuts on labels for textboxes/etc. This dialog can present data in either an editable or a read-only mode. I've received a request to hide the underlines for the shortcuts if the dialog is in read only mode. Other than editing the label text at runtime (ugh) is there any way to remove them? If you don't know what I'm referring to by alt-Letter shortcuts see this question.

  • Combo box in a scrollable panel causing problems

    - by Dennis
    I have a panel with AutoScroll set to true. In it, I am programmatically adding ComboBox controls. If I add enough controls to exceed the viewable size of the panel a scroll bar appears (so far so good). However, if I open one of the combo boxes near the bottom of the viewable area the combo list isn't properly displayed and the scrollable area seems to be expanded. This results in all of the controls being "pulled" to the new bottom of the panel with some new blank space at the top. If I continue to tap on the drop down at the bottom of the panel the scrollable area will continue to expand indefinitely. I'm anchoring the controls to the left, right and top so I don't think anchoring is involved. Is there something obvious that could be causing this? Update: It looks like the problem lies with anchoring the controls to the right. If I don't anchor to the right then I don't get the strange behavior. However, without right anchoring the control gets cut off by the scroll bar. Here's a simplified test case I built that shows the issue: public Form1() { InitializeComponent(); Panel panel = new Panel(); panel.Size = new Size(80, 200); panel.AutoScroll = true; for (int i = 0; i < 10; ++i) { ComboBox cb = new ComboBox(); cb.Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top; cb.Items.Add("Option 1"); cb.Items.Add("Option 2"); cb.Items.Add("Option 3"); cb.Items.Add("Option 4"); cb.Location = new Point(0, i * 24); panel.Controls.Add(cb); } Controls.Add(panel); } If you scroll the bottom of the panel and tap on the combo boxes near the bottom you'll notice the strange behavior.

  • How can I obtain a list of modified files within a 'changeset' range from team foundation server thr

    - by Colin W
    I'm trying to create a tool which will help my team perform code reviews on a more regular basis without it's usual massive overhead. At the moment the manual process involves using Team Foundation Sidekicks to identify the Changesets and then exporting that to excel to filter the results to find which items need to be reviewed (e.g. code files). I've heard mention of using a TFS API, but found very little help online possibly because I was asking google 'the wrong questions'.

  • How to let parent control know that its child got focus?

    - by Axarydax
    Hi there, imagine that I have a Form with 9 controls (TabbedStuffControl) in a 3x3 tile, and these controls contain TabControls containing another control (StuffControl) with ListBoxes and TextBoxes. I'd like to know a proper way to let TabbedStuffControl that its child has received a focus? e.g. user clicks into a textbox of StuffControl or drags something to listbox of StuffControl. Eventually the Form should know which TabbedStuffControl is active Do I need to hook up GotFocus event of TextBoxes and ListBoxes and TabControls, then dispatch another event to finally let Form know who got focus? I think that there should be a simpler way - that somehow TabbedStuffControl knows that its child got focus, so there would be only one place in code that I'll hook up. Thanks.

  • Control.IsAccessible

    - by Gerhard
    I need to check if a c# WinForm Window (FORM Class) has been initialized and waiting for user events. But I could not find out how to manage that. Therefore I had the idea to set the Control.IsAccessible Flag of the Form to true, within the OnLoad Event of the Windows Form. My question is now, what is the Control.IsAccessible Flag origin intended for? Or is there an other solution to check if the Winform is initialized. Thanks for your help

  • datagridview winform tag only brings back the first row value

    - by jvcoach23
    I'm using visual studio 2008. I have a datagridview in a winform. I've bound to it using an object Private Sub LoadAllCampers() Dim Os As List(Of LE.Camper) = Nothing Dim Oc As New LE.Camper_Controller Os = Oc.GetCamperData(0) With Me.dgResults .DataSource = Os End With CamperBindingSource.DataSource = Os End Sub I have a tag setup on the ID property within the Camper class. when i double click on a row in teh datagridview, i do a me.dgResults.tag and it always shows the first rows ID value. If i change the ordering within the class, it will display a different value, but it's always the first value in the datagridview. I'm missing something simple to get this working.. just don't know what it is. Hopefully someone can spare a minute.

  • After drawing circles on C# form how can i know on what circle i clicked?

    - by SorinA.
    I have to represent graphically an oriented graph like in the image below. i have a C# form, when i click with the mouse on it i have to draw a node. If i click somewhere on the form where is not already a node drawn it means i cliked with the intetion of drawing a node, if it is a node there i must select it and memorize it. On the next mouse click if i touch a place where there is not already a node drawn it means like before that i want to draw a new node, if it is a node where i clicked i need to draw the line from the first memorized node to the selected one and add road cost details. i know how to draw the circles that represent the nodes of the graph when i click on the form. i'm using the following code: namespace RepGraficaAUnuiGraf { public partial class Form1 : Form { Graphics graphDrawingArea; Bitmap bmpDrawingArea; Graphics graph; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graph = Graphics.FromHwnd(this.Handle); } private void Form1_Click(object sender, EventArgs e) { DrawCentralCircle(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y, 15); graph.DrawImage(bmpDrawingArea, 0, 0); } void DrawCentralCircle(int CenterX, int CenterY, int Radius) { int start = CenterX - Radius; int end = CenterY - Radius; int diam = Radius * 2; bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graphDrawingArea.DrawEllipse(new Pen(Color.Blue), start, end, diam, diam); graphDrawingArea.DrawString("1", new Font("Tahoma", 13), Brushes.Black, new PointF(CenterX - 8, CenterY - 10)); } } } My question is how can i find out if at the coordinates (x,y) on my form i drew a node and which one is it? I thought of representing the nodes as buttons, having a tag or something similar as the node number(which in drawing should be 1 for Santa Barbara, 2 for Barstow etc.)

  • how to manually deploy a web service on tomcat 6?

    - by opensas
    I'm learning how to develop soap web services with java. So far now I've been following this excelente tutorial http://java.sun.com/developer/technicalArticles/J2SE/jax_ws_2/ it all goes well, I have my web service working from the command line with it's embeded server, and then, with the help of netbeans I deployed it on tomcat. I'd like to know the steps to manually deploy it on tomcat, in order to learn how it's done, and because I don't like depending on an ide. I mean, I'd like to know how everything could be done from the command line and a text editor. I've also found this link that explains how to manually deploy a servlet to tomcat, http://linux-sxs.org/internet_serving/c292.html but I couldn't find any article telling how to deploy a web service... thanks a lot saludos sas

  • Forcing a checkbox bound to a DataSource to update when it has not been viewed yet.

    - by Scott Chamberlain
    Here is a test framework to show what I am doing: create a new project add a tabbed control on tab 1 put a button on tab 2 put a check box paste this code for its code (use default names for controls) public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); this.button1.Click += new System.EventHandler(this.button1_Click); this.checkBox1.CheckedChanged += new System.EventHandler(this.checkBox1_CheckedChanged); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no public CreateHandle() for CheckBox) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads? EDIT-- per Jaxidian's suggestion I created a new class public class newcheckbox : CheckBox { public new void CreateHandle() { base.CreateHandle(); } } I call CreateHandle() right after updating = true same results as before.

  • Architecture Guidance Needed?

    - by vijay
    We are about to automate number of process for our reporting team. (The reports are like daily reports, weekly reports, monthly reports, etc..) Mostly the process is like pulling some data from the oracle and then fill them in particular excel template files. Each reports and so their templates are different from each other. Except the excel file manipulation, there are hardly any business logic behind these. Client wanted an integrated tool and all the automated processes are placed as menus/submenus. Right now roughly there are around 30 process waiting to be automated. And we are expecting more new reports in the next quarter. I am nowhere to near having any practical experience when comes to architecuring. Already i have been maintaining two or three systems(they are more than 4yrs old.) for this prestegious client.The possiblity of the above mentioned tool will be manintained for another 3 yrs is very likely. From my past experience i've been through the pain of implmenting change requests to the rigd & undocumented code base resulting in the break down of the system and then eventually myself. So My main and top most concern is the maintainablity. When i was searching for these i came across this link, Smart Clients Using CAB and SCSF is the above link appropriate for my requirement? Also Should i place each automated processes in separate forms under a single project, or place them in separate projects under a single solution.. Please correct me if have missed any other important information. Thx.

  • Why does this IF statement fail?

    - by ChosenOne
    If variable path is empty, and editor.Text is not empty, the SaveFileDialog should be displayed. Now, why on earth is this damn thing failing??? I have tried this with many different variations of code with the same result: FAIL: if(path.Length >= 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } At the top of code file I have: path = String.Empty; So why the heck it this failing every single time, even after trying all of the below variations? if(path.Length > 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrEmpty(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrWhiteSpace(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } This is making me very angry. How could this fail? Setting a break point reveals that path is definitely null/"".

  • How To Make Moving News Bar in Windows Forms Application without Timer

    - by Ehab Sutan
    I'm making a desktop application in C# which contains a moving News Bar labels. I'm using a timer to move these labels but the problem is that when i make the interval of this timer low (1-10 for example) the application takes very high percentage of CPU Usage, And when i make it higher(200 -500 ) the movement of the labels becomes intermittent or not smooth movement even that the user may not be able to read the news in Comfortable way. ((More Information)) it is Windows form application. the way i move the labels is as follows : the news items from RSS feeds are represented in a group of linklabels. All these linklabels are added to a flowlayout container. The timer moves the whole flowlayout container. I found this way according to my knowledge the best way to making the news bar. If you have better idea or solution please help

  • Is this part of MVC in .NET?

    - by 4thSpace
    I have a .NET MVC winform app. I've created an AppDelegate class that handles application startup and shutdown...for now (it might do more later). Winform apps have a Program.cs file that does some app initialization, starts the message pump and creates the first form. In my app, the first form is AppDelegate, which isn't really a form but is forced that way by Application.Run(). AppDelegate does any further app initialization and starts the first Controller, which then initializes any child controllers (these then create their views). I don't consider events occuring in Program.cs and AppDelegate as part of the MVC. Conceptually, what would these be called?

  • Windows.Forms.Timer instance and UI threads

    - by David Rutten
    I have a custom control whose primary purpose is to draw data. I want to add a ScheduleUpdate(int milliSeconds) method to the control which will force an update X milliseconds from now. Since this is all GUI land, I should be using a Windows.Forms.Timer, but how does this timer instance know which thread it belongs to? What if ScheduleUpdate() is called from a non-UI thread? Should I construct the timer in the Control constructor? Or perhaps the Load event? Or is it safe to postpone construction until I'm inside ScheduleUpdate()? I know there are some very similar questions about this already, but I don't have a Timer component on my control, I'm constructing it on a when-it's-needed basis.
