    - ToolStripComboBox Mimimum Width With .NET 2.0, insert a ToolStrip onto a form and add a ToolStripCombobox item. I don't know if I'm flat out missing something, but I cannot set the width of a toolStripCombobox any smaller than 75. It just seem ridiculous. toolStripComboBox2.Size = new Size(35, 25); When you execute that line of code, you can see it flash that it resizes it down to 35, but then immediately gets resized back up to 75. The same thing happens in the designer. I cannot find any other documentation or posts on this. Hopefully I'm missing something or doing something stupid. Can someone confirm this width problem.

    - Caching Smart Client Lookup Data Hi, We're currently developing a smart client application. It is a WinForms UI that uses WebServices to retrieve data from an Oracle database. The application will have several forms that will use a relatively static set of tables for populating drop-down lists. I'm thinking that caching the data from these tables on the client side, as opposed to bringing them through the Webservice every time would improve application performance to some degree. I'm just wondering if the Caching Application Block is the best route to take for caching static data or is there another recommended approach. The application itself will not be set up to run offline, so I only need limited caching capabilities. Thanks Tag: Memory usage Tag: 100905

    - Combobox does not accept key stroke Hi I am using .net 2.0 windows forms. I have a combobox with following properties. DropDownStyle : DropDown AutoCompleteMode : SuggestAppend AutoCompleteSource: Listitems Now When I run the form and go to the combobox and type something it works just fine. combobox suggest items as well. If user does not select anything from combobox and hit submit button, I am populating datagridview with all data. Now when user select any item from combox and hit submit button i am populating datagridview for that specific item. The problem is user can type into the dropdown and dropdown suggests the item as long as someone clicks submit button first time. As soon I populate the datagrid first time, I can not type anything into the combobox. I want user to type into the combobox and select items at any time. Its kinda strange. I would highly appreciate if someone can help me here. thanks Tag: Memory usage Tag: 100902

    - Custom windows form border, TransparencyKey Flicker Hello, I've got a question regarding a small amount of flicker I am seeing when a form is first drawn that has a transparent background. I have a custom panel that I'm drawing myself which takes up all of the client area of a form (rounded corners, gradients etc). I have set the background color and the transparencykey of the container form to the same values. Everything draws and looks great however right before the form is displayed I see a black flicker or flash right before the form is rendered. It's a really really quick flash. Is there anyway to get around this? I've tried just a blank form and setting the transparency key and the backcolor to the same values with the same result. thanks, bp Tag: Memory usage Tag: 100901

    - ListView selection I have a ListView control, and anytime I manually set the selected item, the original item OnSelectedIndexChanged event fires twice. Here is a sample of what I am doing in the OnSelectedIndexChanged function: if ( listView1.SelectedItems.Count == 1 ) { MessageBox.Show( "index = " + listView1.SelectedIndices[0].ToString() ); if ( isinternal ) return; isinternal = true; if ( last >= 0 ) // last is the last selected index { MessageBox.Show( "Not Shown" ); //behaves regardless if the next line is present listView1.SelectedItems.Clear(); listView1.Items[0].Selected = true; } last = listView1.SelectedIndices[0]; isinternal = false; } else if ( listView1.SelectedItems.Count == 0 ) { } I have 4 items in my ListView. Assume I select index 4. I should see message boxes in this order: index = 4 Not Shown index = 0 However, I really see index = 4 Not Shown index = 0 index = 4 Not Shown index = 0 If I don't manually set the selected index to 0, the control behaves as expected. Why does manually setting the selected index cause this behavior? How can I manually set this index and avoid this behavior? Thanks in advance for your help! Tag: Memory usage Tag: 100879

I can close the application and restart it, then I can view the form without the error?

    - RichTextBox Control Captures Shortcut Keys in Regular Windows App but Fails to Capture in an MDI App? Hello All, First, I apologize for posting this to so many newsgroups but I wasn't sure which newsgroup was most appropriate nor which newsgroup would most likely have subscribers that have done this or would have the answer. That said, below is a description of my problem: If I create a standard Windows executable in C# or VB.Net and place a RichTextBox control on the main form, the control captures standard shortcut keys as expected (i.e. Ctrl-V, Ctrl-X, etc.). However, if I add an MDI parent form to the project, make the original form a child form to this parent MDI form and display the original form, the RichTextBox control no longer captures these shortcut keys. Can someone please tell me what is necessary to correct this behavior? Thanks & Regards, TC Tag: Memory usage Tag: 100865

    - Application Settings I'm just venting. I finally got around to converting a big WinForms app for my biggest client to .NET 2.0. I've heard all along that application settings are now writable, which has always been one of many bones of contention with .NET 1.1 for me. So I get to the point where I am going to convert my custom settings mechanism, do a little investigation, and find out the reason I made a custom configuration file mechanism hasn't changed at all. Sure - you can write user setttings, and settings are type safe now, but the application scope settings are still read-only. (If anybody knows a reasonable workaround that works within the framework for this, I'd like to hear it). I certainly understand MS's reasoning for making them read-only, but I'm more of the mind that in "most cases" the application settings shouldn't/wont need to be written. However, to prevent it altogether is simply stupid, imho. I feel like I'm old enough to be responsible for my own actions by now. I do like the new stuff for user settings and for application settings that don't change, so I'm actually going to use the new stuff for all of that. However, I have one setting that all users must be able to change, and must be the same for all users. I had a custom configuration file, and I allowed write access to its containing folder on installation. I may move this value to the database for now. Or, Gawd Forbid, the Registry! Don't get me started on generic collections! Ok, I'll start, but just barely... Ha! Have you seen the Find() or Exists() method on List? Here's the code to find '6' in a list of ints: List<int> myInts = new List<int>(); myInts.Add( 0 ); myInts.Add( 1 ); myInts.Add( 2 ); myInts.Add( 3 ); int n = myInts.Find( delegate(int x) { x==6; } ); // seems rather obtuse to Find(6), doesn't it? This returns '0'! Ha! int m = myInts.Find( delegate(int x) { x==0; } ); // This returns '0' too! I tried deriving my own collection, and quickly found that two values of type T cannot be compared. I'm sure there's a good reason for this - I just hope there's a better workaround eventually. It makes me wish for the days #define! Even though that's just the tip of the tip of the iceberg of my complaints, I still like it (2.0 that is). It's definitely a step in the right direction. Tag: Memory usage Tag: 100854

    - How can I make a modeless form receive input when a modal form is open? >From my main form, I can open and access a modeless form. However, if I then open a modal form (from the main form), the modeless form will no longer accept keyboard and mouse input until the modal form is closed. Is there a way to allow the modeless form to continue to receive input? As an example, Windows Notepad does this.

    - Problem with no touch deployment of application which has dynamically loaded assemblies We have an application which dynamically loads an assembly and creates instances of classes. For this we have written a factory class which reflects the assembly and creates the classes and returns the created objects as plain objects. The caller method casts the object returned by the object factory into appropriate class object and uses it. All this works fine when exe is invoked directly. But when the application is deployed on the IIS for no touch deployment, the casting of the object returned by the object factory is throwing an invalid cast exception. Strange thing is that the statement that is causing exception during run time works fine if executed in the Immediate window of the VS.Net IDE. How do I fix it? Tag: Memory usage Tag: 100826

    - TextRenderer problem Hi, I'm creating a control that overrides ListView and so I'm working on redrawing everything myself with some changes here and there... But I'm having a problem with drawing the text inside the rectangle on LargeIcon mode... I thought I'd finally discovered the solution with TextRenderer but this still doesn't give the correct results. Here's the code I'm trying to use (item is a ListViewItem) Rectangle text_rect = item.GetBounds(ItemBoundsPortion.Label); TextFormatFlags formatFlags = TextFormatFlags.WordBreak | TextFormatFlags.HorizontalCenter | TextFormatFlags.Top | TextFormatFlags.EndEllipsis; if (item.Text != null && item.Text.Length > 0) TextRenderer.DrawText(dc, item.Text, item.Font, text_rect, item.ForeColor, item.BackColor, formatFlags); The problem is that its still not exactly what the original ListView displays... ie I'm displaying: ___________ | some | | really long | original ListView displays: ___________ | some really | | long text | Surely it should fit inside the bounding box if its using the GDI draw method and I'm using the bounding box thats returned to me from the ListViewItem itself? Any ideas? thanks Kris Wragg Tag: Memory usage Tag: 100820

    - Customization In Web Application All, Using VS 2005, C#.NET, SQL Server 2005, W2K3. We are developing a web application that would be shared by numerous customers for information management. Some of those customers want variations on the usual form layout. For example, we have a form where the user can enter their dependents information (parents, siblings, spouse, kids, etc.), but we know one of our customers wants to include additional information on that form that none of the other customers would use (company specific insurance coverage). Based on our experience with our C/S version of the product, we can expect to see many more requests like this. There are 3 ways to do this that I see. 1. Create a separate web application for that customer and host it on a different web server. 2. Add the custom fields to the single web application but hide the extras based on the customer using it. 3. Allow the customer to add the fields themselves and store them for just that customer. Pros and cons that I see. 1. Quick to implement, but costly in new infrastructure, and would end up difficult to maintain. 2. Still relatively quick to develop, and uses existing infrastructure, but would create complex forms. 3. Difficult to develop, but would use existing infrastructure and wouldn't need extra maintenance. Personally, I'd like to use 3. That is... Design the application so that each form includes standard fields, but a customer can add new labels, textboxes, drop-down combos, lists, etc., themselves and doing so doesn't require us to change any code or the database schema. While this would be a no-brainer in an C/S application, it gets a little more difficult in a web app since the only client they use is a browser. Any thoughts? Tag: Memory usage Tag: 100808

When the processing finish, the waiting form just close. I have done everything and it's work well except for one thing. I wish the waiting form to be modal and own by the main form. If I set the waitingform owner : WaitingForm->Owner = FormA The waitingform doesn't appear before the data process finish, the form disappear as soon as it appear. If I dont set the owner, the waitingform works as expected, but can be lost behind other windows, and user may believe there is a problem when it's not. I use multiple threads in my application. The data processing thread is not the same as formA nor the same as the Waitingform. Does someone have an idea how I can set the ownership of the waiting form and still keep the behavior i wish?

    - Best way to organize large project I am working on rewriting a Fox 7 ODBC app. and teaching myself .NET in the process. So far I have over 130 of the screens rewritten, but debug performance is terrible. It would be much better if I had each screen as seperate solutions, but then I'm constantly having to remove and readd references which became way too much hassel. So currently my solution has the 130+ projects included. But when I start debugging it rebuilds EVERYTHING! eventhough I haven't changed a single thing!! I can play a hand of Solitaire before it finally starts executing. Not finding this situation very productive at all!!! Is there an option that can be set to only rebuild changed modules? Or has the size of my application exceeded the capability of .NET? It sure is looking that way. Or how should an application of this size be organized?

My first idea is to implement the IDataErrorInfo interface in my Comboboxcolumn but there is no effect! Can anybody help me? Thanks Tag: Memory usage Tag: 100741

    - grid component similar to Excel Hi all I need a suggestion. I have a customer that wants the grids in the application i'm going to develop lokoking as much as possible as Excel grids. I suppose he wants the filtering possibilities of Excel in the header of the grid, the possibility to copy&paste from one cell to the other etc. My question is: is there any component that can suit my needs? something that someone used/has used for large scale apps? Please give me a suggestion! Tag: Memory usage Tag: 100736

    - How to control date format in combo Hi All, This SHOULD be simple, but I just can't see it... I have a combo box which uses a dataset as its list source. The displayed member is a date column from the underlying table. When I run it, the date in the combo is formatted as d/m/yyyy hh:mm:ss, which I don't want - I just want the date part. How can I control the format of the date? Do I have to delve into owner-drawing? Surely not! Thanks Tag: Memory usage Tag: 100730

    - Processing Enter on Form Controls I've been having trouble correctly processing the "Enter" key on form controls. Here's what I've done: Set the "AcceptsReturn" property to true Overridden IsInputKey and KeyDown; on KeyDown, if the "Enter" key was pressed, I set e.Handled to true. So now I'm receiving the event, which is good but.... When I press "Enter" in that control (it's a text box, if that makes any difference) I get the Windows "Default Beep." I don't want the default beep. Who else is receiving this event, and why is it causing the default beep? How do I stop this behavior? On a related note: I remember writing Windows software back in the day, and there were handy programs that would show me *all* of the events a particular control received...event watchers. Does Visual Studio have such a program and, if not, I assume there is something out there...if anyone has any recommendations, I would welcome hearing them. Tag: Memory usage Tag: 100726

    - Newlines in TextBox I'm trying to programatically add new lines to the content of a (System.Windows.Forms.)TextBox and, while I have found a solution, I feel that it can't be very efficient. There must be a better way. I first tried: textBox.AppendText( "\n New line" ); But that didn't work. Nor did variations on the theme, like textBox.Text += .... Here's what *did* work: String[] lines = new String[textBox.Lines.Length+1]; textBox.Lines.CopyTo( lines, 0 ); lines[lines.Length-1] = textBox.Text; textBox.Lines = lines; This seems very inefficient since we're copying the *entire* contents of the text box just to add a single new line. Am I missing something here? -- T Tag: Memory usage Tag: 100724

Hi,

What is the typical memory usage for .NET application 2.0.

My app is around 30 meg, but sure sure that older version was around 2 megs.
What would cause dramatic change in size?

Unfortunately, the answer is, "It depends." I have several .NET 1.1
and 2.0 sample and test applications that range from 10 MB to 30 MB of
RAM when they first load. I guarentee you will not find a .NET
application that only uses 2 MB of RAM when it is being used. Sure,
maybe if you minimize the form, it will go down to 2 MB, but only
because it swapped out all that memory to the virtual memory on disk.
