    - Databinding Combobox to ArrayList (again: argh!) An ArrayList contains Person objects with Properties Name, Age, Phone. A Windows Form displays - TextBoxes for these properties as well as - a ComboBox for the Name and - VCR Buttons First/Previous/Next/Last. DataBinding should display the correct information in the textboxes no matter if navigation happens through the VCR buttons or the combobox. The combobox should always contain the same information as the txtName textbox. I tried several combinations of defining the databinding. No matter what combination of the following lines I used, I get errors from "stack overflow" to metadata/type info displayed in the combobox. txtName.DataBindings.Add("Text", myPersons, "Name") txtAge.DataBindings.Add("Text", myPersons, "Age") txtPhone.DataBindings.Add("Text", myPersons, "Phone") cboName.DataBindings.Add("Text", myPersons, "Name") cboName.DataSource = myPersons cboName.DisplayMember = "Name" cboName.ValueMember = "Name" 1) What is wrong? 2) How does the code need to be changed if objects should be added and deleted from the arraylist by additional buttons? thank you, herbert Tag: ANN: 9Rays FlyGrid.Net 1.0 is released.

    - Can't access digital camera to copy from in code I am trying to copy pictures from a digital camera in code. When I use the FolderBrowserDialog, it won't let me select the camera as the folder. I have gotten around this by using Shell32.BrowseForFolder. I am then also able to get the names of the files. However, the path is a pidl (i believe). So I am unable to utilize .Net IO classes to manipulate the files. This is windows form that ultimately will allow the user to browse for a camera, pick a client, then ftp pictures to the server for later processing.

    - Datagrid exception I have a .NET windows forms application with one form displaying data. I have a tree view on the left side and the datagrid on the right side. Tree view allows the user to select verious items and based on that selection the datagrid is bound to the appropriate datasource and table from the database. This works well. The problem comes when I resize my form and the grid portion is not visible or just barely visible. Now when I perform the same operations by selecting various items in the tree I get an exception System.ArgumentException with Message : '0' is not a valid value for 'value'. 'value' should be between 'minimum' and 'maximum'. Source : System.Windows.Forms. This happens when I call SetDataBinding method. When I again resize the form so that the grid is more visible this problem goes away. I have also seen a bizzare display with red cross over the entire grid area when I resize the grid again. Is this a known issue in the datagrid ? Can somebody help me ? Thanks Tag: ANN: 9Rays FlyGrid.Net 1.0 is released. Tag: 85050

    - PropertyGrid - TypeConverter (DropDown) - Internet Explorer hosting problem Hi, I have created a Windows UserControl. This Control hosts a PropertyGrid and a Button control. The UserControl project also includes a class called "TestClass" and a custom TypeConvertor class called "DDConv". When the user clicks on the Button control, the application assigns an instance of "TestClass" to the PropertyGrid. The "TestClass" has a property called "CustProp" and it has an TypeConverter attribute assigned to the "CustProp" property. The TypeConvertor points to the "DDConv" class. The PropertyGrid in the UserControl displays a DropDown against the "CustProp" property when the UserControl is hosted in a windows application. When the UserControl is hosted in Internet Explorer, the PropertyGrid does NOT SHOW any DropDown for the "CustProp" property. NOTE: I test the UserControl in Internet Explorer from a virtual directory on my machine. I have set "FullTrust" for the "LocalIntranet_Zone" on my machine. I want the PropertyGrid to display the DropDown in Internet Explorer - can someone help me in figuring out how to acheive the same?

    - Passing parameters to forms Hi all, I have a function that handles opening child forms in a MDIContainer, I want the child forms to accept a parameter to setup the form when opening. So I simply overloaded the constructor to accept the parameter...that easy enough, however the function that opens the form checks first to see if it's already open and if so just sets focus to that window. Does anybody know how I can setup the form before giving it focus this way? Thanks Gav Tag: ANN: 9Rays FlyGrid.Net 1.0 is released. Tag: 85034

Thats why I fear that i loose the overview in the file Is there some way to easily split the tabs in extra files and also use the FormDesigner of VS.net?

    - How to embed a form in a form? This is what I would like to do: - The splitter window splitting the view to a tree view on the left and entry dialog on the right. The tree view and splitter are easy and it's already done. - It is easy to make a fixed form on the right pane, dock it and enjoy it working. However, I would like the form on the right pane to be dynamic, i.e., depending on a context of the tree view to display different controls and being managed by a different form derived class. In MFC I could accomplish this with child dialogs embedded in a parent dialog and depending on the tree context flipping the child dialogs visible/invisible. I can do the same in .NET by using panels with embedded controls, however, this way everything must be done in the runtime and I lose advantage of designing a forms in a design time and taking advantage of .NET studio wizards. If I could find a way to embed a child form in a parent form, then it would solve my problem. Is it possible? Thanks Tag: ANN: 9Rays FlyGrid.Net 1.0 is released. Tag: 85012

    - Editing a form in VisualStudio Using Visual C# .NET. I have successfully created my own Windows forms from scratch and been able to view and edit both the code and the designer (i.e. right click on the .cs file in the Solution Explorer pane and select View Code or View Designer.) I'm also modifying existing code, and have also successfully edited existing classes using View Code and View Designer. However, in one particular project there is a folder in which I cannot View Designer for the form class - the only option is View Code. Also, the icon shown is different from the usually forms classes - it's not the gray "control-looking" icon, but the green/white "text-looking" option. Both a .cs and a .resx file exist for form classes in question. This is code I got out of a library and my colleague is able to View Designer on these classes just fine. Any idea what's wrong?

    - Need help in Data grid Hi I am developing a windows application. This contains a Data grid which will populate data from a data table in a Dataset. The application will do some calculation and store the result in the Data table. After the calculation, the result stored in the data table will display in the data grid. When number of rows need to populate in the data table after calculation is around 16000, application will take around 30 seconds to do the whole work. Because of this Data grid population from data table will also take 30 seconds or more. During these 30+ seconds, form will be blank and user cannot do any activity. I like to know, Is there any way to display the calculated rows part by part to the data grid from data table. (Like Buffer.Flush in Asp.net, to display part of the out put to the user). If I am able to display 1000 rows after calculation from data table to the data grid, the user no need to wait for whole calculation to be completed for the out put Give me some reply on this.

    - SendKeys doesn't send I'm writing an app that sends keystrokes to another app using SendKeys.SendWait(). On some computers some of the time, the call to SendWait() doesn't work. After it's called, the receiving application is sitting there focused and ready to receive the keystrokes (if I press keys, they work) but the keys never come and the sending app blocks infinitely. Like I said it's only on some computers and even on those computers it's only every now and again. There isn't any difference between the computers that it works on and those it doesn't that I can think of. Does anyone now why this is happening? Todd Tag: ANN: 9Rays FlyGrid.Net 1.0 is released.

    - Building a Word 2003 Document with XML I have an old product that generates a Word document using Word Automation (tables, pictures, etc). The execution speed is quite slow and I'm finally at the point where I can tell my customers that they HAVE to have Office 2003. That brings me to the potential of building a Word document using the Word XML document schema. Has anyone done that - is this possible? Most of the examples I see don't address building an entire document from scratch. Also, can anyone recommend a good reference of the subject? Thanks in advance!

    - Which version of the .NET compact Framework am I using? I know how to tell which version I have installed on my mobile device. But I seem to be missing some libraries that I should have on my development pc and I was wondering how I can tell which version of the CF I have installed. Going into Help/About from Dev Studio tells me the .NET Framework version but not the compact version. Thanks.

    - Control Data Source Assignment Best Practice I notice that if I assign a data source to a control in VS and necessarily call Fill after the assigment has happened, the form will load very slowly. If I hand-assign the data source after calling Fill, much faster. I assume this is because the control is firing off some event on a per row basis every time a row gets loaded into the dataset. But whatever the reason, what's the best practice here? Using the designer seems like a waste of time if there is such a high performance price. Is there a workaround for this? Thanks!

    - listbox problem in vb.net I'm having a problem getting listbox items to show up in VB.NET. I'm using a test program that has one form with a listbox. I'm using this code in the form load event: Dim x As Integer For x = 1 To 50 Me.ListBox1.Items.Add("Item " & x.ToString()) Next x Dim i As Integer i = Me.ListBox1.Items.Count The count property is correct (50), but nothing shows up in the listbox. I can select rows, but all are blank. Any ideas? Tag: ANN: 9Rays FlyGrid.Net 1.0 is released. Tag: 84930

    - DataGrid adds blank row in typed DataSet I have encountered a strange behavior with the WinForms DataGrid which can be reproduced as follows: 1. Create a new Windows Application 2. Set Form1.IsMdiContainer = True 3. Add a new DataSet named DataSet1 4. Add an new element named Table1 to DataSet1 5. Add two columns named "ID" and "Name" to Table1 in DataSet1 6. Add a new Windows Form named Form2 7. Add a Datagrid to Form2 named DataGrid1 8. Add a DataSet of type DataSet1 to Form2 9. Set the DataGrid1.DataSource = DataSet1 10. Set DataGrid1.DataMember = "Table1" 11. Add the following code in Form1 Load event: Dim f As New Form2 f.MdiParent = Me f.Show() Run the application. Form2 shows up with 2 rows in DataGrid1. One blank row (containing (null) in both columns) and the AddNew row (the one with an asterisk). Where did the first row come from? It has somehow been added to Table1 in DataSet1. If I change the code to not include "f.MdiParent = Me" there is no blank row added, just the AddNew (asterisk) row is shown. Could someone please explain why the blank row is added when Form2 is a MDI child? Tag: ANN: 9Rays FlyGrid.Net 1.0 is released. Tag: 84926

    - Question: ScrollableControl resets position of child Controls I have created new ImageControl : Control which displays an Bitmap image. I placed Image Control inside Panel which has Autoscroll property set to true. then I placed Panel into Frame and made it fill the whole client area. When I run application everything works fine, I can see and use scroll bars to change Location of Image. Here is where the problem is. When I resize the Frame or bring it back and then to Front (regain focus) the location of Image is being reset to (0,0). Here is sequence of events I captured from ImageControl. location change {X=-179,Y=-342} invalidated {X=-179,Y=-342} move {X=0,Y=0} location change {X=0,Y=0} got focus Why is Location of child control is reset to (0,0)? did I make a mistake putting together tree of controls?

    - Subclassing the PropertyGrid Folks - I've done some searching on the 'net, and I think I know the answer to my question, but I wanted to pose it anyway, just in case. I'm embarking on a new project, and we're investigating the use of the PropertyGrid. I've used it in a couple of places before, but never in an application that goes out to my general user base. We really like the functionality and capabilities it provides, but some of the display choices are not exactly what we want. Some initial tests of creating an inherited control (and my above-mentioned searching) seemed to show that I'm SOL if I want to override the drawing of the control elements. I really do not want to go through the effort of re-creating the majority of this control just so we can draw a couple of things differently. Any ideas?

    - When is ContainerControl.ParentForm set? From my windows control I want to access a property on its parent form. I would like to do it as soon as possible after the control's creation. The question is: what is the good moment to do this? I tried from OnLoad, and this works fine until the control is put into a tab control. Then I get ParentForm = null. Is there an event that notifies all controls that initialization of everything (or at least Parent properties) has completed? -- Boris Drajer <boris.drajer@do.not.s.p.a.m.micro-bs.com> Tag: ANN: 9Rays FlyGrid.Net 1.0 is released.
