    - TreeView Question I have a tree view that i'm populating with a lot of heiracheral data. I only want to populate a node with children if the user expands it. However, that presents a problem. If I do not populate it with children then the expand/collapse bitmap does not appear. So, my question is how do I make the expand/collapse bitmap appear without actually adding any children nodes? Assume that I know there will be children nodes to add if the user expands it. -- -Demetri Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109596

    - Programming the Windows Forms Datagrid? Hi, Using Windows Forms 1.1 (VB.NET) I have a datagrid on my form and no datasource, just a collection of Parameters (for a stored procedure selected by the user at runtime) which have been populated by the user. I want to display all these parameters in the datagrid so the user can review them before executing the stored procedure. How do I dynamically add columns and rows to the datagrid please - I basically want to loop through the collection of parameters (in this case a VB Collection containing Oracle Parameter objects, but it can also be SQL Parameter objects)? thanks Philip Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109594

    - Referencing .NET classes from Crystal Reports Hi, I have a project containing all of my Domain object classes. I have another project containing my Crystal Reports.

    - axWebBrowser control and javascript errors hi all, Has anyone come across working code for a Windows Forms application that uses AxWebBrowser control and is capable of intercepting and dealing with the 'Internet Explorer Script Error' (An error has occured in the script on this page') type errors. I know the WebBrowser control (the one that comes by default in Visual Studio Toolbox) has 'ScriptErrorsSuppressed' property that seems to achieve just that, but I don't have much time left for re-implementation. After doing some searching on the web, some of the possible solutions that I've seen included: 1) setting aXWebBrowser.Silent = true at an appropriate time. The downside of this approach is that some of the pop-ups are useful, such as authentication prompts etc. 2) implementing IOleDocumentSite, IOleClientSite and IDocHostShowUI interfaces and using IDocHostShowUI::ShowMessage for the purpose of intercepting the message box. I have attempted this but am yet to see the ShowMessage function invoked... 3) implementing IOleCommandTarget and the QueryStatus and Exec methods, and then watching out for the Exec invocation with OLECMDID_SHOWSCRIPTERROR. From what I understand this behaviour doesn't work if Disable Script Debugging check box is cleared in Internet Explorer settings. apologies that this post is not actually directly related to HtmlEditor :| regards, Greg Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109579

    - Cannot call Invoke or InvokeAsync on a control I have some sort of a concurrency problem that has me stumped. I have a form (actually several) that run background worker threads from the OnLoad method. Sometimes... occasionally... I get a crash dump from a user that indicates that I "cannot call Invoke or InvokeAsync on a control until the window handle has been created." Now, never mind that by the time OnLoad runs, the window handle should already be created. I decided that, hey, if that's the problem then I'll just patch it. My patched code is below. As you can see, in the DoBackgroundWork method I added a test for control.IsHandleCreated, and then if it's not I do a control.CreateControl. However, even after this patch I had a crash this morning with this same annoying message. 2007-03-01 06:36:54Z User mm_tboos on PRICTX99, running M:\program files\StockCodeGenerator\StockCodeGenerator.exe (StockCodeGenerator version 2.4.2615.30559) received the following exception: 2007-03-01 06:36:54Z System.InvalidOperationException: Cannot call Invoke or InvokeAsync on a control until the window handle has been created. 2007-03-01 06:36:54Z at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) 2007-03-01 06:36:54Z at System.Windows.Forms.Control.Invoke(Delegate method, Object[] args) 2007-03-01 06:36:54Z at Agama.Controls.BackgroundWorkParameters.DoBackgroundWork(Object parameter) Do I have misconceptions about when handle creation happens?

    - Error When Trying to copy a row from a datagrid Hi, I have a vb.net windows form with a datagrid, and I am simply trying to click on a row, hit CTRL-C to copy and then CTRL-P to paste it somewhere else. This works fine for individual cells. When I try it with an entire row however, I get the following error: DataGridColumnStyle of '' cannot be used because it is not associated with a Property or Column in the DataSource. This error occurs as soon as I hit CTRL-C. Strangely the unhandled exception occurs at the definition of the parent form ("Public Class Mainform"), even though the datagrid is located on a child form. Does anyone know what is going on. I want to be able to copy and paste whole rows, but even if I can't, I really can't have the users getting unhandled errors for trying. Anyone seen this before?

    - Opening MDI Child From MDI Child Form, like VisStudio Start Page Hi, I have an MDI application which contains a start page with a listview of items in it that can be used to click on and open as a child form. So the start page is the child at start up of form. However, when I try to open another child from this start form it opens ok, but will not show or focus on the new form, it keeps coming back to itself? Why would this be? I open the form like so from the start page. MPE.PolForm polWin = new MPE.PolForm(); polWin.Show(); and then in the polForm I do this.MdiParent = mainForm; and mainForm.windowManagerPanel1.AddWindow(this) Any ideas? The windowManagerPanel1 is a tabbed form control that behaves like visual studio 2005. Why does it always go back to the start form and not show the new created form.

    - Europe Tests Established Chemicals on Millions of Animals Tony Nottingham England 28 February 2007 TO: All People Who Care A new European Chemical Testing Policy called REACH has now been finalised by the European Union. Under these proposals Chemicals of every kind - from those used in industrial processes to the ingredients of consumer products - will be tested on Millions of animals from mice to fish to dogs, causing untold suffering. Still worse, because of this reliance on outdated animal techniques, reliable and relevant information will not be provided and our safety will not be assured. If you believe that REACH should make more use of Alternative Testing to test 1000s of Chemicals that have been in general use since before 1985 then please take action now. If you are a European citizen please contact your local papers and own MEP asking them to promote the development of humane non-animal testing methods under the REACH legislation, which is the best hope we have for sparing animals the misery of a testing laboratory. A sample letter can be found at the BUAV (British Union for the Abolition of Vivisection) website at www.BUAV.org (Select Campaigns, Chemical Testing, Get Active then Writing to the local press). For all Non-European members, you can still help. Please tell all your colleagues and friends in the UK and Europe about REACH. Write to your own local papers to try and inform others about what is going on in Europe. The website for the European Parliament is http://www.europarl.europa.eu. Information on REACH, the New European Chemical Testing Policy can be found here. Everyone can help and you can make a difference.

B : datetime picker in DD-MM-YYYY default format ( europe , NL-NL localization ) refuses an entry of 31 on the DD filed cause the month is already chosen to the current mont ( (02) februari wich only has 28 days ) steps to reproduce these problems A : can be reproduced on any system Throw a datetime picker control , and a textbox on a form ,set the Datetime picker format to short , start the project , now enter a date , move the focus to the textbox with the tab key , move the focus back with the tabkey , you will notice that the when the focus is given back to the datetime picker control it will select ( highlight ) the last entry box instead of the first that we expected B : can only be reproduced on a system with DD-MM-YYYY settings , when the form is started the Datetime picker will start with the current month ( 2 ) however if i want to enter 31-12-2006 i need to change the month part first Why is the above a problem ? Well we are currently building a production system , and for data entry this behavior is verry unwanted as it will take extra steps for the operator to enter valid data in the system . For B : i have coded a solution however not completely to my satisfaction i just default the control to 31-12-YYYY ( where YYYY = the current year ) however A: is a serious problem that i can`t solve yet regards Michel Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109535

    - Remove last row in a unbound datagridview Hi All, I have a undound DataGridView. That is, I am populating the DataGridView using the DataGridView.Rows.Add() call and by setting the values to individual cells in the row. When I am adding data to the DataGridView using such a method, I am getting an unwanted row at the bottom of the DataGridView. I want to avoid this row. Any help with respect to this is highly appreciated. I am not planning to use databinding for the DataGridView. Since, the DataGridView has 7 columns. I should be able to sort the DataGridView using any of these seven columns. If I use the databinding, it will be difficult to sort the view. Hence, using the Default sort of the DataGridView helps me in this case. But the presence of last row in the DataGridView should not be supported. So, please tell me a good method, using which I can remove the unwanted last row in the DataGridView.

    - How to improve performance for stock exchange data display received from third party com component Hi, I could not get the answer on the Performance community hence forwarding the same issue here... I am using a third party COM component to get very very fast data stream. I have dragged the com component on a windows form. Now we can request the data for specific symbols on this com component and in turn it will start pouring in data in form of continuous events for the requested symbols. The problem is that data stream is too fast and can easily make the CPU go to 100%. The tricks which I am thinking to tackle the issue are ... 1) Instantiate the com component form on the new thread and put the data in alternate generic dictionaries (We have 2 side by side dictionaries. One dictionary start filling with data then other dictionary is being accessed by the consumer module) . So a dedicated thread of consumer class with poll in the alternated dictionary after a certain time interval, set the flag on 1 dictionary and start copying the data from alternated dictionary to another datastructure BindableDictionary(It is a wrapper arround 2 data structures - 1 BindingList<> and 1 Dictionary<>. As the name suggest, as soon as the consumer module copies data in BindableDictionary, it start displaying it on UI.) [STAThread] private void InstantiateCOMComponent(object state) { _comManager = comComponentForm.GetInstance(); Application.Run(new comComponentForm()); _comManager.Visible = false; } but as soon as we try to instantiate the COM component on the new thread, it gives the error - Message "ActiveX control '7b0deade-e17b-11d2-93e6-00a0c91827c9' cannot be instantiated because the current thread is not in a single-threaded apartment." 2) Because of the com component error, Another alternative could be to apply the com component on a windows form in a new exe and make it a server. Then supply data through sockets to clients. Please suggest/comment about the alternatives given above or any better way of solving the business problem. I appreciate you reading a long email.

    - Binging custom objects to the DataGridViewComboBoxColumn Hi, I have bound a collection of type IBindingList to a DataGridView. Each object in the collection contains various string properties, Customer Name, Contact Name etc. It also contains a property 'MyOrder' of custom type 'Order'. The Order class simply contains properties like OrderID, OrderName etc. I add the columns to the Grid of type DataGridViewTextBoxColumn for the strings and DataGridViewComboBoxColumn for the 'Order' object, the code for the combo column is as follows: DataGridViewComboBoxColumn cboCustmomerOrder = new DataGridViewComboBoxColumn(); cboCustmomerOrder.HeaderText = "Order"; cboCustmomerOrder.DataPropertyName = "MyOrder"; cboCustmomerOrder.Name = "OrderName"; //cboCustmomerOrder.ValueType = Order; cboCustmomerOrder.DataSource = m_Cust.OrderCol; this.dataGridView1.Columns.Add(cboCustmomerOrder); The datasource is set to a collection of type Order (List<Order>) Everything displays OK and I can make selections from the dropdowns. When I try to tab away however, I get the following error: [System.FormatException] = {"Invalid cast from 'System.String' to 'BusinessComponentExample.Order'."} I have spent ages trying to find out how to handle this but so far only found that the error can be trapped as follows: private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e) { if (e.Exception != null && e.Context == DataGridViewDataErrorContexts.Commit) { //Do something } } Obviously I need to cast to type 'Order', but my question is how? Hope this all makes sense, please let me know if not. Would be delighted to get an answer or a pointer to a good tutorial. Couldn't find any that explain how to do this.

    - FindRows() doesn't find last entered row in a DataGridView... Hi: I'm using FindRows() to locate rows in a DataGridView. When adding new rows consecutively, the last row added is not found when calling FindRows(). It's not until you shift focus away from newly added row by selecting other rows will it find it. It's like it's not being committed. What is workaround for this? THanks, Charlie Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109490

    - Using WPF as a Wizard - XBapp vs XAML Win Form Hi all, I am currently maintaining a web based survey tool that is very poorly written. I see no reason for leaving it as a web based application and many good reasons for making it a windows forms based application. I know that by using an XBapp (XAML Browser Hosted Application) you can create a wizard like application that goes from one page to the next. I want to be able to use some of the functionality that will not be allowed however if I go that route, i.e. saving to the local file system. Dose anyone know if I can get that same navigation scheme (Like a Wizard) in a straight up XAML Win Forms application? -- Thank you, John Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109470

    - IDE BindingSource error message I used the Data Sources window to drop a custom object onto the designer surface. It created a BindingSource and BindingNavigator as a result. When I open the Properties window on the BindingSource, I see DataSource property set to the object I created. However, when I try to dropdown the DataSource property, I get the message: "Object reference not set to an instance of an object". The title of the messagebox is "Microsoft Visual Studio". So I cannot change the DataSource! I went into the designer file and removed the DataSource property of the BindingSource and went back into the designer. It showed the DataSource as (none) as I expected. But the same error message occurs when I try to change the property with the dropdown box. What is going on?

    - Tooltip on Combobox disappears - Windows Forms bug? I am using .NET 2.0 forms and running on Windows XP SP2. When I have a tooltip on a combo box, and the combo box is expanded (?dropped down?) using the arrow, then collapsed, it will no longer display it?s tooltip, no matter how long I hover. Even if I move off the control and back it will still not display its tooltip. If I then go to another control that has tootips, then back to the combobox, it will again display its tooltip, until the next time it is expanded. Below is a small sample that has this bug (on my machine anyway.) It is simply the standard VS8.0 generated code, condensed. Strangely, if I remove the EnableVisualStyles() line, then the tootips seem to work correctly. I could not find any information about this bug. I am curious if anyone else has come across it, and if there is a solution? Any help appreciated. ======= Buildable Code Sample Below using System; using System.Collections.Generic; using System.Windows.Forms; namespace ComboTest { static class Program { [STAThread] static void Main() { Application.EnableVisualStyles(); Application.Run(new Form1()); } } class Form1 : Form { public Form1() { InitializeComponent(); } private System.ComponentModel.IContainer components = null; protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.comboBox1 = new System.Windows.Forms.ComboBox(); this.toolTip1 = new System.Windows.Forms.ToolTip(this.components); this.button1 = new System.Windows.Forms.Button(); this.SuspendLayout(); // comboBox1 this.comboBox1.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList; this.comboBox1.FormattingEnabled = true; this.comboBox1.Location = new System.Drawing.Point(12, 59); this.comboBox1.Name = "comboBox1"; this.comboBox1.Size = new System.Drawing.Size(121, 21); this.comboBox1.TabIndex = 0; this.toolTip1.SetToolTip(this.comboBox1, "Combo Tooltip"); // button1 this.button1.Location = new System.Drawing.Point(12, 12); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(75, 23); this.button1.TabIndex = 1; this.button1.Text = "button1"; this.toolTip1.SetToolTip(this.button1, "Button tip."); this.button1.UseVisualStyleBackColor = true; // Form1 this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.button1); this.Controls.Add(this.comboBox1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); } private System.Windows.Forms.ComboBox comboBox1; private System.Windows.Forms.ToolTip toolTip1; private System.Windows.Forms.Button button1; } } ====== END Code Sample Tag: Edit Report Created in Report Designer within Rebuild Builder Tag: 109467

    - IDocHostUIHandler ShowContextMenu problem with one of the args I have created a context menu when a user right clicks on a link. I've implemented IDocHostUIHandler and post the menu if the right click happened on a link: public uint ShowContextMenu(uint dwID, ref tagPOINT ppt, object pcmdtReserved, object pdispReserved) { Write(string.Format("Context menu on: {0}", pdispReserved.GetType().ToString())); if (pdispReserved is HTMLAnchorElementClass) { // create the menu ..... return 0; } return 1 } On some PC's the first time the user right clicks a link, the above method is calles, but the menu is NOT posted because the type of the pDispReserved object appears to be "System.__ComObject" instead of "HTMLAnchorElementClass". Why is the pdispReserved object sometimes "System.__ComObject". Can anyone explain what "System.__ComObject" is?

    - Prompt to save changes I have a winforms app with a tabbed interface. I would like to prompt users to save their changes when they switch from tab to tab and don't click the Save button. I have tried using the Tab Validated event to prompt them, but it fires when they click Save, and when they don't. It also fires when they just click in a field. Is there an event, or something I can look at on, say, the Leave event of the tab to see if they have made changes to the data?

Hi,

I have a couple of reports that I created within the SQL Report Designer, I
would like to give the ability to the end user of C# Winform application to
be able to make modification to this .rdl file using the Report Builder,
however when I try and launch the report that I created within the Report
Designer using the Report builder I get the following error..

Microsoft.ReportingServices.ReportBuilder.ReportModel.Report: The report
'http://localhost/ReportServer/MyReport)' cannot be opened because no data
source is associated with it. Associate a model data source with this report
and try again.

How can I resolve this situation.

Thanks

Technically, you are only supposed to be able to go from Report Builder
to Report Designer and not the other way around.

That being said, if you follow these suggestions at the link, you can
still bend the rules:
