    - cannot send emails with attachments from .NEt 1.1 using cdonts Hi all, environment : windows 2003 using remote desktop, .netf framework 1.1 using VB.net with Visual studio 2003 users log into the application over remotedesktop to windows 2003 server and access the application. the application lets the users send out emails of reports which have attachments and this is done using the system.web.mail namespace of .net in my vb code and i think this namespace is using the cdonts object. Email with attachments are send out successfully but only under the windows administrator type accounts and not user type accouts, it gives me a huge error saying not able to create CDONTS. Message object. And seems this restriction applies only for emails being send out with attachments, if there is no attachment with the emails that there is no problem. can any body tell me why this is happening? here is the code that i user to send that email : mailmsg.To = torecepient mailmsg.From = fromrecepient mailmsg.Attachments.Add(New MailAttachment(FullPathAndName)) mailmsg.Subject = subject SmtpMail.Send(mailmsg) how can i send out emails with attachments from my application using this namespace even under the windows user type accounts ? thanks Tag: Deploying desktop app Tag: 110822

    - BindingSource - how can I access nested member?

    - Seeking Textbox with "popout" for longer text - like Vis Studio 05 Project Settings Still a newbie at this: I'm trying to find a ways to get a textbox control to behave similar to the beahvior of the control seen in the Visual Studio IDE > Project ? [Application Name] Properties > Settings tab. On that page, the 'value' column is normlly displayed as a single line. However, it is possible to click the down arrow in the cell to pop-out a larger editor to accomodate more text. can something like this be easily accomplished with a standard textbox (i.e., without a grid?)? I'm far from making my own controls at this point, and this functionaility is just the thing I need for cases where 90% the data fits a single line, but ocassionally is much longer. thanks in advance d.

    - No data appearing in my report I'm putting together a REALLY simple report for my WinForms app. I use an object data source. Here's the class: -------------------------------------------------------------------------- public class ProjectEnergyUsageReportValues { private double defaultUsage; public double DefaultUsage { get { return defaultUsage; } set { defaultUsage = value; } } private double oldUsage; public double OldUsage { get { return oldUsage; } set { oldUsage = value; } } private double newUsage; public double NewUsage { get { return newUsage; } set { newUsage = value; } } } -------------------------------------------------------------------------- No brainer. I have an embedded RDLC file. When I created the RDLC file, I added the class to my data sources window, and dragged the properties (DefaultUsage, OldUsage, NewUsage) to the "data fields" section. I see the three of them listed there. When I added the ReportViewer control to my form, I used the smart tag to associate it with the RDLC file I created. Here's what I'm doing in my report form constructor: -------------------------------------------------------------------------- reportViewer1.ProcessingMode = ProcessingMode.Local; ProjectEnergyUsageReportValues reportValues = new ProjectEnergyUsageReportValues(); reportValues.DefaultUsage = 5.0; reportValues.OldUsage = 6.0; reportValues.NewUsage = 7.0; BindingSource bindingSource = new BindingSource(); bindingSource.DataMember = "ReportValues"; bindingSource.DataSource = reportValues; reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("ProjectedEnergyUsage_ReportValues", bindingSource)); -------------------------------------------------------------------------- And finally, in the form load event: -------------------------------------------------------------------------- this.reportViewer1.RefreshReport(); -------------------------------------------------------------------------- When I run the app and open the form, I see the report layout fine, but there's no data. Any idea why? Tag: Deploying desktop app Tag: 110808

    - Simple Rich Text Parser/Painter? I have a DataGridView with a column that needs to display text that may be normal or bold, has user specified color and can handle hyper text links. The obvious solution was to derive from RichTextBox. I figured out how to get a real RichTextBox control to handle the edit functions but I have not been as successful in displaying the results once the edit control has been disposed of. Any suggestions how this might be accomplished? I can think of two approaches - display the RichTextBox editor's contents as a bitmap or write a simple RTF parser and paint the results on the cell. I'm leaning towards the parser but have not found sample code on which to base my own implementation. Would someone be so kind as to give me the benefit of their experience with this particular problem? -- Richard Lewis Haggard www.Haggard-And-Associates.com Tag: Deploying desktop app Tag: 110806

    - DataGridView custom cell - losing first character on edit I've created a RichTextBox DataGridView cell but the first character entered when the cell is in display mode is lost when the cell makes the transition to edit mode. What is the sequence of events that happens behind the scenes when: a) RichTextBox cell is displaying data and has focus. b) User enters a keyboard character. c) Cell transitions to edit mode. When the edit process starts, the editor control collects the data that is present in the cell and sets its own value to it. Initially, of course, this is an empty string. Any subsequent keystrokes are properly handled by the RichTextBox control but the initial keystroke that triggered the display of this control is lost. I did do one odd thing - I got tired of having that stupid page show up that said design mode was unavailable for the RichTextBoxEditingControl so I encapsulated the RichTextBox itself into a User Control. The RichTextBoxEditingControl is derived from the RichTextBox encapsulating User Control and this makes Visual Studio '05 happy. public partial class RichTextBoxControl : UserControl { // Accessor to allow operations on the contained RichTextBox // The child RichTextBox control was added to the UserControl form as richTextBox. public RichTextBox RichTextBox { get { return richTextBox; } } public RichTextBoxControl() { InitalizeComponent(); } } public class RichTextBoxEditingControl : RichTextBoxControl, IDataGridViewEditingControl { // Bunches of code to implement the IDataGridViewEditingControl interface. // Influenced by the MSDN DateTIme Calendar sample. // ... } Any suggestions on where the lost character is going to and, more importantly, how I can get it into the RichTextBox? -- Richard Lewis Haggard www.Haggard-And-Associates.com Tag: Deploying desktop app Tag: 110805

The DGV has AutoGenerateColumns = False and I have created the columns I want in the designer. When I make any change to the code behind, even something innocuous like a new line, and then switch back to the designer, it automatically generates the columns in my binding source and adds them to the ones I created manually. Also, I don't see AutoGenerateColumns anywhere in the DGV's property sheet. Am I missing something? I'm using the latest SP. Any ideas? Tag: Deploying desktop app Tag: 110797

    - Empty NumericUpDown Hello, I have a small problem ; I have found an alternate solution but I don't like it. The problem is simple, let's take a form, a numericUpDown inside and a button that will show the value of the numericUpDown in a MessageBox (or elsewhere, whatever). Let's say you put '5' in the numericUpDown, click the button, "5", ok. Now, erase the '5' in the numericUpDown, click the button, still "5" but _nothing_ in the numericUpDown. My problem is that I would like to catch when the user erases what's inside the numericUpDown in order to put in the MinimumValue or just display the actual Value. Of course, I don't want it to be ReadOnly. My alternate solution is to use numericUpDown.UpButton() then numericUpDown.DownButton() but as I said, I don't like it. If anyone has encountered the same problem and found a (better) solution, I would like to read it. Thanks, -- neva Tag: Deploying desktop app Tag: 110794

I know how to get around this, by putting code behind every control to see if theres a change and then set a flag, but thats a waste of time and a lot of code to write. I can see someone having a much more elegant solution, I just can't work it out. I was thinking of having every control inherit some master control so I can have one peice of code that 'detects' when a change has been made to any field or check box, just not sure how to go about it.

    - Total Loss of control in VS.net 2005 code window I'm now consistently having a problem (shortly after SP1), that, heretofore, only happened once in a while. Now, I bring up the code window in VB.Net 2005 - and I loose total control - I type in a letter or two (most of the time, it's only one), and the intellisense seems to think that's all I need - the code window loses focus, sometimes thinking I'm finished, and adds parentheses at the end. Then, no matter what, I click in the code window, and I can't type in but 1 letter - then it does it again. When it first started happening, I could just shut down VS.Net - then re-open it, and it would be OK for a good while - - I'm loosing my mind with this - Does anyone have any ideas on what may be causing this?

    - "default" Desktop and Ctrl+Alt+Del Hello, I'm currently programming an application which is started replacing the userinit.exe. The code does the following. When the user logs on the application is creating a new desktop "newDesktop", then the original userinit is created at "newDesktop". So the shell uses "newDesktop" as its desktop, too. The same is with the other applications, that are started when the user logs on. After starting the original userinit the program creates another desktop "formDesktop" where the forms of my Desktop are displayed, while the system configuration of the logged on user is loaded in the background. In this form the user has to solve some tasks and when this is done correct the "formDesktop" closes and the "newDesktop" is set as visible Desktop and the program exits else the user will be logged off. For sure you ask why "newDesktop" for the shell process? The answer is that when the user logs on the visible desktop is "default". If I don't use "newDesktop" the user can manipulate the desktop before the form is displayed and this cannot be allowed. If the application sets the "default" desktop visible before exit the hotkeys and trayicons and so on are still registered to the "newDesktop" and not the "default" desktop, so "newDesktop" stays the user's desktop for the session. What is the problem I have? Well, the ctrl+alt+del event opens the taskmanager in the "default" desktop, thus it's invisible to the user, although the process exist. Making the long story short, here is the question: Is there a way to make the taskbar appear in the "newDesktop" when ctrl+alt+del is pressed? I hope I could make myself clear. kind regards, Alexander Tag: Deploying desktop app Tag: 110772

    - DataGridView: last column can be made smaller but not bigger Hi, I have a DataGridView control where the user can resize the columns. The control is embedded inside a Panel. When clicking on and dragging the column seperator to the right of the rightmost column, I can make the column smaller when I move it to the left. If I try to move it to the right however, my cursor is halted against the edge of the control. So the column can't be made bigger. This can be reproduced in the sample at http://msdn2.microsoft.com/en-us/library/1x64c23x.aspx by clicking Customer->View Orders in the main form and doing it on the table that appears. In that sample, it is possible to make the last column bigger again by making the whole window bigger, until its length is more than the total length of the columns, creating an open space between the columns and the edge of the window. Then the right seperator of the rightmost column can be dragged freely, up until the edge of the window. However, this trick isn't practical in my own control, since the control is too small and the total column length too long. Is there some standard way to make it behave like the list view in Explorer, where you can resize past the border of the window? Kind regards, Raf Tag: Deploying desktop app Tag: 110762

My code executes the following steps: public void BuildView() { ... // suspend layout to not perform layout each time an item is added mFlowLayoutPanel.SuspendLayout(); // remove all elements from the panel: mFlowLayoutPanel.Controls.Clear(); // in a loop I add new items to the panel: foreach (... in ...) { Panel panel = new Panel(); // set size of the panel: panel.Size = MaxSize; // MaxSize is a constant value // then the color of the panel is set panel.BackColor = Color.CornflowerBlue; // after all the panel is added the the panel with the flow layout mFlowLayoutPanel.Controls.Add(panel); } mFlowLayoutPanel.ResumeLayout(true); } Every time the method BuildView() is called, the panels are flickering.

    - Child form focus problem Hi all, An application I am woking on consist of a main form. On the main form there are several possible ways for the user to open a non-modal child forms to display even more information. The problem I am encountering is about loss of focus. Let's say here, that initialization of the child form takes about =BD second, from the point where the window is first shown to the point where all controls have been rendered and set with data. Now, on the main form there is a datagridview which is updated on intervals. The problem occurs the user clicks a button to open a child form. The child form is created. But before initialization of the child form has finished, the DataGridView on the main form is updated. Seemingly because of this, the main form gets focus and is moved to the front, and the child form is moved to the back. The user can manually put focus on the child form again and continue working, but tuhis is a behaviour that is very anoying to the end users. Have any of you encountered something like this before? The non-modal strategy is by design. The users want to be able to go back to the main form, without closing the child form. Therefore, I'm searching primarily for any help on the focus problem, and will only use a modal child form strategy if no resolution to the problem can be found.

    - OnPaint automatically call e.Graphics.Clear()? Hello. I have a question about OnPaint override. For example, if i have the following code in my inherited form class, private Brush _brush = Brushes.Black; private RectangleF _rect = new RectangleF(0,0,100,100); private int counter =0; protected override void OnPaint(PaintEventArgs e){ if (counter==0){ counter++; e.Graphics.Clear(Color.White); e.Graphics.DrawString("Test", this.Font, _brush, _rect); } } I expect the OnPaint method will do nothing after the first call. That means, the string "Test" should stay on screen if the form is not resized/moved/covered by other windows. However, in reality, the OnPaint do the e.Graphics.Clear() automatically. I'd like to know if that is possible for me to stop that behavior. In my application, my form contains many individual text strings. The strings are updated periodically individually. I would like to render the updated strings only, not rendering the whole thing for every string update. Thank you very much for your help! Gilbert Tag: Deploying desktop app Tag: 110726

    - Filtering key strokes Hi, having a card reader attached to the PS/2 keyboard interface, I would like to filter the keyboard input, so that the input from the card reader does not reach the GUI controls. I tried setting KeyPreview=true on the form and catched all input with the KeyDown event. In order to detect, if the input comes from the card reader, I need to check a sequence of at least 10 keys. So I collect the keys in KeyDown and if it's a card reader sequence, I trigger a special action for it. If it's normal user input, I need to "forward" the collected key strokes to the form. The second part is the complicated one. Having a sequence of key strokes in an array of type System.Windows.Forms.Keys, how do I resend these to the application? Sendkeys only accepts a string and seems to not support all values of the System.Windows.Forms.Keys enum. Is there maybe a way to resend keystrokes using the integer values captured from the KeyValue member of the KeyEventArgs? bye, Marc T. Tag: Deploying desktop app Tag: 110724

    - ClickOnce & proxy authentification We have developed a VisualStudio 2005 smart-client application which we deploy using .NET framework 2.0 ClickOnce. We are experiencing difficulties deploying in certain corporate environments: clients that use proxy authentification simply cannot install unless they disable the proxy which is usually not an option. Apparently this is a known issue with ClickOnce and Microsoft has released a HotFix for it: http://support.microsoft.com/kb/917952/en-us Could we please receive a copy of this HotFix? This is a huge and recurring problem that makes us look bad. Tag: Deploying desktop app Tag: 110720

    - Forms and Labels I wonder if you could help. The event handler code below, will allow the user to change the phone number and write it on a label of a message box. I want to replace the message box with a dialog box. Can anybody help me replace the message box below to a dialog box. In other words. I want to write the new phone number on a label (named "labe1")of a dialog box (named "dialog2),instead of writing the new phone number on the label of a message box. private: System::Void dialogBtnItem_Click(System::Object * sender, System::EventArgs * e) { // Create the dialog MyDialog* box = new MyDialog(); //Fill in the initial data box->Phone = S"(650)123-3456)"; // <------ This is the phone number to be changed //Show dialog if (box->ShowDialog() == DialogResult::OK) { MessageBox::Show(box->Phone); //<-----I tried to change this line } } Tag: Deploying desktop app Tag: 110713

    - What are my options in this Windows App? I am creating a Windows Forms app that will use SQL Server as the database. The app will be used in the following ways. 1. It will be used in the Clients office where the app will sit on the clients desktop pc and connect to the database on the server. 2. It needs to be used by those outside of the office network. ex. a remote office that is not a part of the network where the database is residing. 3. I might have users on the road that with wi-fi access need to connect to the office database. I don't want to create a browser based app using ASP.Net. I don't want to use Citrix. Here's what I think are my options. Am I missing any? which would you recommend? 1. Create a windows forms app that sits on the client and a web service that sits on the server that connects to the database. The user does something on the client and a call is made for data to the webservice which returns data to the client. 2. The app creates an opens up a port upon startup and accesses data directly and then closes the port upon exiting the app??????????????????? Any other suggestions or recommendations?

    - Accessing a forms control menu I've got some base classes I'm creating with a specific set of functionality that needs to be present throughout our app. I'm not finding any way to programmatically get to the control menu in the upper left of each window. I've always been able to add to this in the past. How do I get access to this now? We're using VStudio Team Suite .NET 2.0.... Thanks! Tag: Deploying desktop app Tag: 110696

    - Detecting a tray control Hi there, I need to determine if an arbitrary control appears on a form's design tray or the actual form itself (or other parent container). Is the following check reliable or is there an official way (or something cleaner). Thanks. public static bool IsTrayControl(Control control) { return (TypeDescriptor.GetProperties(control)["TrayLocation"] != null); } Tag: Deploying desktop app Tag: 110694

    - is there a 'flush' type method in VB.Net Here's the scenario - I'm iterating through a directory, dynamically adding picturebox controls to a container, with a For Loop On screen, you don't see anything until it actually fully populates In ASP.Net, there is a command - Response.Flush - you can put this before the end of the loop, to make the page show what's just been done. Is there anything like this in VB.Net? (I hope I've fully explained the need) Tag: Deploying desktop app Tag: 110690

What are the advantages/disadvantages in allowing a .net app to be executed
from a network share? All the user machines will be configured to have
fulltrust from this share.

Is deploying to a networkshare with proper trust better over oneclick
deployment ?

Here is a post which gives details about how to use Caspol to configure a
network share for full trust.
