  • Does not contain a definition

    - by JB
    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 ""; } } } }

  • DataGridView update datasource directly after changed Checkbox value

    - by SchlaWiener
    I have a System.Windows.Forms DataGridView that is bound to a List<MyObject>. The class MyObject contains a boolean property that is bound to DataGridViewCheckboxCell within the DataGridView. public class MyObject { public decimal DefaultValue {get; set; } public bool HasCustomValue {get;set; } public decimal CustomValue {get;set; } public decimal CurrentValue { get { return HasCustomValue ? CustomValue : DefaultValue; } } If I change the value of HasCustomValue another (readonly) property CurrentValue changes it's value, too. That is done by implementing the INotifyPropertyChanged event (I left that part in the source example for simplicity) If I changed HasCustomValue from outside the DataGridView, the column bound to CurrentValue gets updated immediately. Howevery, If the users enables/disables the checkbox, HasCustomValue is not changed in the underlying datasource unless he leaves the column by clicking with the mouse or pressing the TAB key. Is there a way to force the grid to update the datasource directly after changing a checkbox value? If I bind a Control Property I have the ability to set the DataSourceUpdateMode to Windows.Forms.DataSourceUpdateMode.OnPropertyChanged but I haven't found anything like that in a DataGridView

  • Autoupgradeenable property of openfiledialog.

    - by Harikrishna
    I had need of showing open file dialog in winform application. And one property of the file dialog, autoupgradeenabled which I set as a true, which is for updating the open file dialog according to operating system, like if application is running on xp then dialog is displayed different as in wista or window 7. So when I used that property as a true, and once in the machine where there was xp with 2.0 .net framework that open file dialog could not be opened. So I tried by doing it false then also it could not be opened in the machine with the xp and 2.0 framework. Then I tried by commenting that whole line means I removed that property from the code, then I tried and it was fine in xp machine with 2.0 framework. So problem is I cannot understand that why that property is not working by setting it false or true. Because by setting that property is should work in all os with all framework and dialog should be changed according to os. If not,then what is the meaning of that property ?

  • What, if any, printable character did a user type based on the values in a given System.Windows.Form

    - by Corey Trager
    As a workaround for a problem, I think I have to handle KeyDown events to get the printable character the user actually typed. KeyDown supplies me with a KeyEventArgs object with the properities KeyCode, KeyData, KeyValue, Modifiers, Alt, Shift, Control. My first attempt was just to consider the KeyCode to be the ascii code, but KeyCode on my keyboard is 46, a period ("."), so I end up printing a period when the user types the delete key. So, I know my logic is inadequate. (For those who are curious, the problem is that I have my own combobox in a DataGridView's control collection and somehow SOME characters I type don't produce the KeyPress and TextChanged ComboBox events. These letters include Q, $, %.... This code will reproduce the problem. Generate a Form App and replace the ctor with this code. Run it, and try typing the letter Q into the two comboxes. public partial class Form1 : Form { ComboBox cmbInGrid; ComboBox cmbNotInGrid; DataGridView grid; public Form1() { InitializeComponent(); grid = new DataGridView(); cmbInGrid = new ComboBox(); cmbNotInGrid = new ComboBox(); cmbInGrid.Items.Add("a"); cmbInGrid.Items.Add("b"); cmbNotInGrid.Items.Add("c"); cmbNotInGrid.Items.Add("d"); this.Controls.Add(cmbNotInGrid); this.Controls.Add(grid); grid.Location = new Point(0, 100); this.grid.Controls.Add(cmbInGrid); }

  • A submenu (`ToolStripMenuItem`) does not show automatically.

    - by czuk
    I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

  • Call panel.invalidate outside form class in C#

    - by Shaza
    Hey, I need to call "panel.invalidate" outside my form (WINform) class also I need to change some other controls as well, I read similar question here, and tried what they said, but it didn't work and I wasn't convinced at all. The answer I read was about exposing a public method like this: public void EnableButton(bool enable) { this.myButton.Enabled = enable; } Also I made a static instance in the other file static Form1 myForm = new Form1(); Any useful suggestions??

  • How can we block the user from unchecking a DataGridView checkbox?

    - by hawbsl
    We have a DataGridViewCheckBox column bound to a boolean property in our class. The property setter has some logic which says that under certain conditions a True flag cannot be changed, ie, it stays checked forever. This is on a per record basis. So the entire column can't be readonly, only certain rows. Pseudo code: Public Property Foo() As Boolean Get Return _Foo End Get Set(ByVal value As Boolean) If _Foo And Bar And value = False Then //do nothing, in this scenario once you're true, you stay true Else _Foo = value End If End Set End Property Databinding is handling all of this fine, except that the checkbox is visibly cleared when it's clicked. Then, of course, when the binding / setter is fired (as you move off that cell) it is restored to its checked status per the underlying logic. Ultimately it doesn't matter too much but it's a clumsy bit of UI. How can we intercept the user's click and keep it checked?

  • On XP, how do I get the tooltip to appear above a transclucent form?

    - by Daniel Stutzbach
    I have an form with an Opacity less then 1.0. I have a tooltip associated with a label on the form. When I hover the mouse over the label, the tooltip shows up under the form instead of over the form. If I leave the Opacity at its default value of 1.0, the tooltip correctly appears over the form. However, my form is obviously no longer translucent. ;-) I have tried manually adjusting the position of the ToolTip with SetWindowPos() and creating a ToolTip "by hand" using CreateWindowEx(), but the problem remains. This makes me suspect its a Win32 API problem, not a problem with the Windows Forms implementation that runs on top of Win32. Why does the tooltip appear under the form, and, more importantly, how can I get it to appear over the form where it should? Edit: this appears to be an XP-only problem. Vista and Windows 7 work correctly. I'd still like to find a workaround to get the tooltip to appear above the form on XP. Here is a minimal program to demonstrate the problem: using System; using System.Windows.Forms; public class Form1 : Form { private ToolTip toolTip1; private Label label1; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } public Form1() { toolTip1 = new ToolTip(); label1 = new Label(); label1.Location = new System.Drawing.Point(105, 127); label1.Text = "Hover over me"; label1.AutoSize = true; toolTip1.SetToolTip(label1, "This is a moderately long string, " + "designed to be very long so that it will also be quite long."); ClientSize = new System.Drawing.Size(292, 268); Controls.Add(label1); Opacity = 0.8; } }

  • A null value should be considered as 0 when addition of it is done with decimal value.

    - by Harikrishna
    There are three column in the datatable A,B and C. Now each column is type of decimal. Now I am doing like dt.Columns["A"].Expression="B+C"; to make addition of Column B's record and column C's record. Now if there is any value of B or C is null then addition of B and C will be null like B's value is 3 and C's value is null for first row then B+C(3+null) will be null which is not appropriate, the result of addition should be 3.If I replace 0 instead of null then it will be ok.But whereever there is null value in the records it should be remain it is and it should not be replaced by 0.That is null value should not be replaced by 0 and when addition of null value is done with any decimal value null value should be considered as 0. Is it possible,how can we do this ?

  • How to know there is something in the cell or not ?

    - by Harikrishna
    I have table like below in the html file: <table border="1"> <tr> <td>BuyQuantity</td><td>SellQuantity</td> </tr> <tr> <td>15D</td><td>&nbsp;<span style="font-family: &quot;Arial Unicode MS&quot;;"><o:p></o:p></span></p></td> </tr> <tr> <td>&nbsp;<span style="font-family: &quot;Arial Unicode MS&quot;;"><o:p></o:p></span></td><td>38D</td> </tr> <tr> <td>&nbsp;<span style="font-family: &quot;Arial Unicode MS&quot;;"><o:p></o:p></span></td><td>99D</td> </tr> <tr> <td>38D</td><td>&nbsp;<span style="font-family: &quot;Arial Unicode MS&quot;;"><o:p></o:p></span></td> </tr> </table> There are two columns: buy-quantity and sell-quantity.(It is only example but in each html file there is different content in the table.) Now with the content of these two columns I want to decide there is items bought or items sold.Like in the first row there is 15d buy-qauntity then items were bought and in the second row there is 38d sell-qauntity then items were sold and so on. And after deciding there is items-bought or items-sold I want to build one column named buy/sell for this table like below: ![alt text][1] [1]: http://C:\Documents and Settings\Administrator\My Documents\My Pictures\untitled.png How can I do this ?

  • Clicking MDI children form doesn't bring it to front

    - by Steve
    This is a winform question in .net. In a MDI form, if I open several children forms, for some forms, if they are not activated (if you overlap them with the activate one, they are not up to front. Only the activate form is up to front.), clicking them don't bring them to front. This is even true if I click controls on them, such as a textbox. The textbox gets focus and you can intput things, but that form is still not activated. Interestingly enough, this is not the case for all the children forms I created. Some forms behave correctly but others don't. Did I do something wrong? I think the correct behavior is that, everytime I click a form, bring it up to front. Thank you for any suggestion.

  • If Html File Has No Ending "/tr" Tag OR "/td" Tag Then HTML Agility Pack Does Not Read That Informat

    - by Harikrishna
    I am using HTML Agility Pack to parse html content. I am using parsing to extract table information. It works. But if there is no ending "/tr" tag or "/td" tag then it does not parse that information perfectly.(in which there is no ending tr tag or td tag.) Like <TABLE border=0><TBODY><TR height=20><TD class=xl27boL noWrap width="7%">01890345&nbsp;</TD> <TD class=xl27boL noWrap width="4%">1416</TD> <TD class=xl27boL noWrap width="7%">kjlkjkls&nbsp;</TD><TD class=xl27boL noWrap width="4%">14:01:57&nbsp;</TD> <TD class=xl27boL noWrap align=left width="15%">Football</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">50&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boRLnoWrap align=right width="8%">249612.64&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">249.86</TD><TD class=xl27boL noWrap align=right width="5%">4992.2528</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boRL noWrap align=right width="8%">249612.64&nbsp;</TD> </table> So for that what should I do ?

  • vb.net add text to form without interaction

    - by user228058
    I have a winform project which lists all the files in a specified folder. It allows the user to select a new destination for each file, and when the user has chosen the destinations for all files that he would like to be moved, it moves the files, one by one. My next step is, I need to display a confirm form when the files are being moved, and add each file's name and destination to the confirm form as it is being moved. My question is: How can I add more text to the confirm form's controls after I already loaded it (using confirm.showdialog() from my other form, without any user interaction? I imagine that I need to do it from the original form, because it needs to display each one when it starts to move that file, but I'm open to any suggestions:) TIA

  • Call Dispose() on a WindowsIdentity object? C#

    - by Andy
    I am retrieving a WindowsIdentity object by calling: win_id = System.Security.Principal.WindowsIdentity.GetCurrent(); with the intention of getting the currently logged on user name, which works fine. WindowsIdentity implements IDisposable, but since I din't create the object myself, do I still need to call .Dispose() on it when I am finished with it or not? Thanks.

  • Labelsize appears bigger in VB.Net

    - by Ikke
    I'm trying to stack a few lists on top of each other. But the label.size.height appears to be bigger then the label itself. When i set the borderstyle to fixedsingle, i see the border around the text. But the height is bigger, so there comes a space between one label and the next. I have tried to set margin and padding to 0 without result. Exemple: label.size.height return 23, when the height actually is something around 15. Does someone knows how i get the right size? Edit: When i explicitly set the height of the lable, the problem is solved. Is this some problem with autosize?

  • Autoscale Font in a TextBox Control so that its as big as possible and still fits in text area bound

    - by blak3r
    I need a TextBox or some type of Multi-Line Label control which will automatically adjust the font-size to make it as large as possible and yet have the entire message fit inside the bounds of the text area. I wanted to see if anyone had implemented a user control like this before developing my own. Example application: have a TextBox which will be half of the area on a windows form. When a message comes in which is will be approximately 100-500 characters it will put all the text in the control and set the font as large as possible. An implementation which uses Mono Supported .NET libraries would be a plus. Thanks in advance. If know one has implemented a control already... If someone knows how to test if a given text completely fits inside the text area that would be useful for if I roll my own control. Edit: I ended up writing an extension to RichTextBox. I will post my code shortly once i've verified that all the kinks are worked out.
