    - Comunication Between Threads Hello, could anyone give me a help on the best way to transmit the results of a function in a thread to where she has started from ? Problem is if i'm not in error that the function launched by the thread has to be void... So, I can't return anything. What's the best way to do this ? I have heard of IPC but don't have mutch knowledge of this but looks like "you" write the data to a file and then read the file, from the main process. Thank You in advance for any help.

    - Convert Access application to .NET? I have a small-medium sized Access application that is poorly written. My choices are to either rewrite large parts of the Access app so that it functions reasonably well, or to convert the whole thing to .NET. Not being an Access developer, the .NET approach seems most natural, but I want to do the right thing for the client (even if I end up giving away the contract). I posted on the Access forum and got the impression that my fears about Access being an unstable piece of junk were unfounded, and that most of the things that need to be done in this type of application could be done quickly and easily in Access and the rest could be coded as one would do in any other environment (just have to give up the "free" things that Access provides). Does anyone have any experience with this type of conversion? I would be interested in your thoughts. Alfredo Tag: Comunication Between Threads C# Tag: 73602

    - Preventing forms from showing up before their layout is completed Hi, When my forms show up (i.e. visible set to true), they show up immediatly while their components (labels etc...) are still being displayed. This gives the application a very unprofessional feeling. I would like to know if there's a command to fix that. I would like my components (forms, panels) to not show up until everything in them is processed and ready to be displayed. Thanks in advance for any help! Ana L.

    - Complex properties in custom controls I have a control, let's call it MyControl. One of the properties of MyControl is MyControlStyle. MyControlStyle is a class with a number of properties. MyControl always has a valid instance of MyControlStyle (it is instantiated in the field declaration). In the property grid, I want to lay out the items in MyControlStyle when someone selects a MyControl on the form. They are all simple data types and don't require any sort of custom designers or anything in themselves. How do I get the properties of MyControlStyle to show up in the property grid without duplicating the properties in MyControl. I mean, if I have to pass the properties through like that then it's kind of pointless to have the MyControlStyle class separate. Thanks. Pete Tag: Comunication Between Threads C# Tag: 73585

    - WinForms, Events, and Subscribers Background -------------------------- I am in the process of creating a WinForms app with many forms. I have a set of forms that all subscribe to events on a custom object. When the forms are created I manually create a subscription in the form to one or more events in the custom object. (BTW, this is the same design pattern used by IssueVision discussed at DevDays). I have a controller form (MDI parent) that determines which child form is currently being viewed. When a new child form is selected, the current child form is manually closed [using Form.Close()] and disposed [using Form.Dispose()] and then the new form is shown. This keeps only one child form open at a time. Question -------------------------- Even after child forms are closed and disposed, when events are raised from the custom object, the events are still triggered in the disposed child forms. Could someone explain why this is happenning? I must be misunderstanding something. Do the child forms need to manually unsubscribe from the events in the Closing event? Is there a better place to do this? TIA, Doug Tag: Comunication Between Threads C# Tag: 73583

    - Need advice on making a MessageBox replacement I'm looking to make an enhanced MessageBox. I want to make it work very much like the regular MessageBox as far as developers are concerned, so I'd like to use the Show() method to display it. However, I want it displayed modally, which we normally achieve with ShowDialog(). Is there a way that the called form can force itself to display modally, or can you think of another way I can do this? Another question I have is about icons. I want to pass a standard MessageBoxIcon enum to the Show() method and then display the OS-specific icon that was requested. In other words, it'll look different on XP than on 2000. To this end I can't simply stick a graphic in my assembly. I can probably figure out how to DRAW the icon myself, it's RETRIEVING it from the system that's beyond me right now. Suggestions?

    - ImageList Errors - What a crap! Hi, Whenever I add images to imagelist and running my application I encounter this error: ------- An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll Additional information: Exception has been thrown by the target of an invocation. Then it highlights the following line in my application code: Me.ImageList1.ImageStream = CType(resources.GetObject("ImageList1.ImageStream"), System.Windows.Forms.ImageListStreamer) -------- Also, the value of "Me.ImageList1.ImageStream" is "Nothing". I have looked up some Microsoft site for this, but couldn't really solve this problem since it happens for images of every size .

    - Raise Format event of Binding class Hello everybody, Iâ??m creating a Bindind class descendent, in this class I only add one property and one method, the property is an class that provides methods to format the data on the Format event of Binding class and to parse the data in the Parse event of Binding class. This works fine, but in some times in my application (when the way of how the data formatted is changed) I need that to force the Format event to be raised, but how can I do it? I didnâ??t find any method to do this, looking at stack trace I only have found private methods (maybe I'm wrong)â?¦ Iâ??ll be very grateful with any kind of helpâ?¦.

    - DataGrid Refresh problem I have a data grid refresh problem. I have a few columns and the first column is data in the form of numbers. And in the form of the data grid if I specify for example something like a code(in a text box) the column of numbers should change colors depending on whether the number was in the specified code(if it belongs to the code, color the cell (first column) in Red and if not in some other color). It all works out fine until I scroll up/down and trigger the paint event. The changed colurs seem to be changed. I want the refreshing to be done for all records for that column, but it seems it only refreshes parts of the datagrid. How do I make the refreshing to be done to the whole datagrid rather than a part of it, so I can get the original colur change for each cell of the first column. Code //method to be passed into the coloumn style that determines the color public Color MyGetColorRowCol(int row, int col) { // just conditionally set colors based on row, col values... short number = 0; short retval = 0; Color c = Color.PaleGoldenrod; if (col == 0) { number = array[cIndex]; retval = GetIfInChannelOrNot(code, number); if(retval==0) { c = Color.LightGreen; } if(retval!=0) { c = Color.Red; } cIndex++; if(TotalNumbers == cIndex) { cIndex = 0; } } else { c = Color.LightGray; } return c; } //delegate required by custom column style public delegate Color delegateGetColorRowCol(int row, int col); public class DataGridColoredTextBoxColumn : DataGridTextBoxColumn { private delegateGetColorRowCol _getColorRowCol; private int _column; public DataGridColoredTextBoxColumn(delegateGetColorRowCol getcolorRowCol, int column) { _getColorRowCol = getcolorRowCol; _column = column; } protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight) { // the idea is to conditionally set the foreBrush and/or backbrush // depending upon some crireria on the cell value // Here, we use a delegate to retrieve the color try { backBrush = new SolidBrush(_getColorRowCol(rowNum, this._column)); foreBrush = new SolidBrush(Color.Black); } catch(Exception ex){ /* empty catch */ } finally { // make sure the base class gets called to do the drawing with // the possibly changed brushes base.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight); } } } Tag: Comunication Between Threads C# Tag: 73540

    - Displaying cells in the DataGrid with their original formatting Hi, I've noticed an unexpected behavior with the DataGrid control. Cells that have special formatting only display their special formatting (such as diferrent bg color, text wrap etc.) when the user clicks on them. Is there a way to somehow make the datagrid display the all cells in their original formatting automatically, rather than only when clicking on them? I'm mostly interested in this behavior because i want the cells that span over more than one line to wrap text. I've already found a way to change the rows' height (using the help of the incredible SyncFusion site!), so i thought it would be nice to also have text wrapping in the cells when the height is right. I wonder if it can be done using reflection, because i didn't see any public or prortected properties for changing this behavior. Thanks for any suggestions :-) Tag: Comunication Between Threads C# Tag: 73534

    - Form's KeyDown delegate not called when in DropDownList ComboBox I have a form with a delegate set up for the KeyDown event. I have set KeyPreview=true and the delegate is called correctly whenever I press a key, except if the active control on that form is a DropDown ComboBox. If I change that ComboBox to be DropDownStyle=ComboBoxStyle.DropDowList the delegate fires when I press a key in that control, as I would expect. The problem is I don't want to restrict the ComboBox to a fixed list of options. The user needs to be able to select, or type their own option. I have reproduced this in an extremely trivial app - one form, two comboboxes, one delegate, and no databinding etc. Does anyone know whether I could be doing something else that has created this problem, or whether this is a known bug? I have searched but can't find a post that seems relevant. Thanks, Scott. Tag: Comunication Between Threads C# Tag: 73501

    - Empty value in binded combo box Hi all. I have to display a dialog adding a new DataRow into the DataTable (say, dtMain). One field (say, "Location") of dtMain is a reference to the "ID" field of the other table (say, dtLocations) and I want this field to be shown on the dialog form as a list of values of all "Name" fields of dtLocations, not as a list of "ID" numbers. I bind as follows: // Making referenced data displayable by their names dlgEditor.comboBoxLocation.DataSource = dtLocations; dlgEditor.comboBoxLocation.DisplayMember = "Name"; dlgEditor.comboBoxLocation.ValueMember = "ID"; The other requirement is that initially I have to display the empty Location field on the dialog form. dtLocations does not contain a row with empty "Name" value. Of course, I would be glad to do dlgEditor.comboBoxLocation.SelectedValue = "" or something like this but I get a natural exception. This is what I do. Before I show the adding dialog form, I add the temporary DataRow into dtLocations with empty "Name" field: DataRow rowWithEmpty = dtLocations.NewRow(); dtLocations.Rows.Add(rowWithEmpty); dlgEditor.comboBoxLocation.SelectedValue = DBNull.Value; // or "" Then I show the dialog, everything looks fine. After the dialog isclosed, I delete this temporary row from the dtLocations: dtLocations.Rows.Remove(rowWithEmpty); This works (the only thing I don't like is that this temporary empty value is available among combo box values) but I am not sure I did what I had to do in this situation (I am a newcommwr in .NET). Is there any smarter decision? Thanks, Dmytro Pavlov. Tag: Comunication Between Threads C# Tag: 73497

Everything else is working (i get the number of pages, etc). What could be happening? Thanks, José Araujo Tag: Comunication Between Threads C# Tag: 73482

    - ListView Control: Can Header Column Colors be changed I have a listview control and default column header colors are black. Can I dynamically set each column header of the listview to a different color? Goal is to have: 1) column headers different colors(i.e column one blue, second column red third column header green etc) 2) can subitems also get set to different colors (not by row). appreciate any guidance. thanks ngottlie@bassocap.com Tag: Comunication Between Threads C# Tag: 73479

    - How to capture UserControl mouse events in it's container Hello, I want to be able to capture UserControl mouse events by the container of the UC. My final goal is to be able to move at run-time the UC in the container. I have been able to do this with regular controls, by capturing the MouseDown,MouseMove and MouseUp events. But when it comes to UserControls, the mouse events are captured by the UC's different controls and not the container. I have tried setting the Capture property of the container to True but it does'nt help. If someone knows the answer to this, please let me know. Thanks Tag: Comunication Between Threads C# Tag: 73470

    - Datagrid: Bind to custom collection, layout at design time I am binding a datagrid to a custom collection of data objects. I will be doing this quite often for the app I am working on, so I have a practical issue: Are there any tricks that will allow me to configure columns in the grid at design time? From what I can tell, this can only be done when binding to a DataTable dropped on the form at design time. Setting all the column characteristics in code is going to get quite tedious.

    - MDI Child From Problem Our team is working on an MDI application. When we create a MDI child form in the normal fashion, assigning MdiParent property to the reference of the main form. The child form displays ok with the maximize and minimize button. But, when the child form is maximized the control buttons for the child window are not displayed in the menu bar of the main form. This makes it impossible to restore the sizeo of the child form. Does anyone have a hint or idea what may be going on here? TIA, Jim Tag: Comunication Between Threads C# Tag: 73464

    - Using LogonUser to authenticate a user Hi, I need the ability to authenticate a user within my application against a specific domain. The machine where the application is running might be part of this domain, another domain or no domain. I am trying to use the LogonUser API which seems to work fine when the machine is part of the target domain, but it does not work when the machine is not part of a domain. The ultimate goal is that once the user authenticates, I impersonate the user and connect to a database using SSPI. Is there some way that I can achieve this functionality? Thanks.

    - Is there an event after form activation? I am trying to run a method on a class in a wondows application(C#). The application has only one form(let's say frmMain). The method on the class has some event handler and I want to print the messages from those events on to the frmMain. I have tried to run the method under from activation event.The method runs ok but I can't see the messages until the method call is completed (and it defeat the purpose). The problem is--the form itself has not been painted completely. So my question is--where do I run the method? Thanks, Prodip Tag: Comunication Between Threads C# Tag: 73460

    - The "Visible" property of a parent control ruins that one of its child controls Hi all, I got a problem: I have a Panel control which has many mixed child controls (buttons, checkboxes, comoboxes). All controls are visible (the parent container Panel is also visible). My problem is that when I set the Visible property of the Panel to false and try to read the Visible property of any of its child control, the result is always false??? How can I get the original value of the Visible property of any child control?? I'd appreciate your prompt reply, Thanks a lot .. Veszko /****************************/ Panel pnl = new Panel(); . . . pnl.Visible = true; Button btn = new Button(); . . . btn.Visible = true; pnl.Controls.Add(btn); . . . MessageBox.Show(pnl.Visible.ToString()); // The result is "True" MessageBox.Show(btn.Visible.ToString()); // The result is "True" pnl.Visible = false; MessageBox.Show(pnl.Visible.ToString()); // The result is "False" MessageBox.Show(btn.Visible.ToString()); // The result is "False" ... which is not OK!!! // I need to know the original value of "btn.Visible" /****************************/ Tag: Comunication Between Threads C# Tag: 73457

    - Coping in .NET I have a ListView control with several columns and rows worth of data. What I wantto be able to do is to allow the user to hit copy and it will copy this information to the clipboard. Then I would like the user to be able to open up any of the following application; Excel, Word, PowerPoint or WordPad and be able to paste the data into these applications. In Excel it should obviously paste the information into the different columns and rows. In Work and PowerPoint I would like to be able to create a table put the information into the applications this way. Ideally pasting into WordPad would also work and just provide the data, in neat format, like tab between the columns and enters between the rows. Basically I want it to act similar to if you copy information from Excel and try and paste it into these other applications. Tag: Comunication Between Threads C# Tag: 73450

Sorry I forgot to specify the language I am using the language I'm using
is C# .
Hello,
could anyone give me a help on the best way to transmit the results of a
function in a thread to where she has started from ?
Problem is if i'm not in error that the function launched by the thread
has to be void... So, I can't return anything.
What's the best way to do this ?

I have heard of IPC but don't have mutch knowledge of this but looks
like "you" write the data to a file and then read the file, from the
main process.

Thank You in advance for any help.
Fernando Ribeiro
