• c# - sqllite dosnt save data i inserted

  - by samy

  I'm messing around with SQL lite and learning it. I got a table called People, I got some method that connect to the database and do some stuff, like show all the info. Now I'm trying to insert some data and here it get wierd for me. I have this method: private void ExecuteQuery(string txtQuery) { SetConnection(); sql_con.Open(); sql_cmd = sql_con.CreateCommand(); sql_cmd.CommandText = txtQuery; sql_cmd.ExecuteNonQuery(); sql_con.Close(); } and to see all the data I've got this method: private void LoadData() { SetConnection(); sql_con.Open(); sql_cmd = sql_con.CreateCommand(); string CommandText = "SELECT * FROM People"; DB = new SQLiteDataAdapter(CommandText, sql_con); DS.Reset(); DB.Fill(DS); DT = DS.Tables[0]; dataGridView1.DataSource = DT; sql_con.Close(); } When I inset some data and right afther it I call the LoadData(), I can see all the changes I made. After I close the program, and then open it agian and call LoadData(), I don't see the new info that I inserted before. I got some data that I used SQL lite GUI app to insert, and I can see that data every time I call the LoadData() method, but not mine. Do I need to do somthing else to make sure SQL lite saves all the data?

• Text property in a UserControl in C#

  - by yeyeyerman

  I have a control with a inner TextBox. I want to make a direct relationship between the Text property of the UserControl and the Text property of the TextBox. The first thing I realized is that Text was not being displayed in the Properties of the UserControl. Then I added the Browsable(true) attribute. [Browsable(true)] public override string Text { get { return m_textBox.Text; } set { m_textBox.Text = value; } } Now, the text will be shown for a while, but then is deleted. This is because the information is not written within the xxxx.Designer.cs. How can this behviour be changed?

• Application window sent behind other windows on closing different thread (C#)

  - by david.murrant

  I'm writing a Windows Forms Application in C#.NET On startup, the application displays a splash screen which is running in a separate thread. Whilst the splash screen is showing, the main application is initialising. Once the main application has finished initialising, the main form of the application is displayed, and the splash screen still shows over the top. Everything so far is as expected. Then, the Splash screen is closed, which causes that thread to exit. For some reason, at the point, the main application windows gets sent behind all other open Windows, notably the Windows Explorer window where you clicked the .exe file to run the application in the first place! What could be causing the windows to suddenly jump "behind" like this?

  - by JPJedi

  I have an Microsoft Access Database (.accdb) that stores information needed in an application. Is there a way to distribute my application with the access database without having the user have access installed or get the user to go and download and install the office runtime?

  I want to display to my user how many (percent wise) of their forms are compliant with the new standard. The way I want to let them know visually is the percent amount will be colored. It will be 0xFF0000 (pure red) for 0% and 0x00FF00 (pure green) at 100%. What is the best way to calculate the color for each step along the way?

• In a Windows forms application, how can I use a listbox in a DataGridView coloumn instead of a combo

  - by Alex

  I'm working on a windows forms application that uses a DataGridView. Some of the cells contain a DataGridViewComboBox. In some cases, I have several values to display in the combobox. For that scenario, it would be better to use a ListBox instead of a ComboBox. Is it possible to use a multi-column listbox within a DataGridView instead of a ComboBox? If so, can you point me in the right direction? Thanks much. Al D.

• Best way to implement some type of ITaggable interface

  - by Jack

  I've got a program I'm creating that reports on another certain programs backup xml files. I've gotten to the point where I need to implement some type of ITaggable interface - but am unsure how to go about it code wise. My idea is that each item (BackupClient, BackupVersion, and BackupFile) should implement an ITaggable interface for highlighting old, out of date, or non-existent files in their HTML or Excel report. The user will be able to specify tags in the settings. My question is this, how can a user dynamically specify a "tag" such as File Date 3 days old? - Background Color = Red. Actually I guess my question is more, how can I, the programmer, implement this dynamically? I was thinking Expression trees, but am unsure this is the way to go as I havn't studied them much. I know my ITaggable interface would have methods such as AddTag(T tag), RemoveTag(T tag), but what exactly specifies the criteria for the tag to be added? I realize this may be subjective, and can be marked as wiki if need be, but I truly am stuck. Any input would be greatly helpful!

• Restore WindowState from Minimized

  - by tbetts42

  Is there an easy method to restore a minimized form to its previous state, either Normal or Maximized? I'm expecting the same functionality as clicking the taskbar (or right-clicking and choosing restore). So far, I have this, but if the form was previously maximized, it still comes back as a normal window. if (docView.WindowState == FormWindowState.Minimized) docView.WindowState = FormWindowState.Normal; Do I have to handle the state change in the form to remember the previous state?

• Is there a way to organize a icon collection to allow for easy searching?

  - by John M

  Is there any way of organizing a icon collection so that it easier to find needed icons? For example: the program needs a save icon there are 5 icons collections on your HD that have a save icon and there are 5 more collections that don't have a save icon (but you don't know that) do you browse through each icon collection? run a search (assumes files are named consistently)? Would it be ideal to have some sort of organized directory (printable?)?

• Form doesn't resize smoothly with a timer event

  - by BDotA

  I have a grid control at the bottom of my form and it can be shown or hidden if user wants to show/hide it. So one way was to well use AutoSize of the form and change the Visuble property of that grid to true or false,... But I thought let's make it a little cooler! so I wanted the form to resize a little more slowly, like a garage door! So I dropped a Timer on the form and started increasing the height of the form little by little while the timer ticks... so something like this when user says show/hide the grid: timer1.Enabled = true; timer1.Start(); and something like this on the timer_click event: this.Height = this.Height + 5; if(this.Height -10 > ErrorsGrid.Bottom ) timer1.Stop(); It kind of works but still not perfect. For example it lags at the very beginning, stop a like a second and then start moving it...So now with this idea in mind what alterations do you suggest I should do to make this thing look and work better?

• C# chart control Performance with large amounts of data

  - by user3642115

  I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series. The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down. Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues. Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens. Thanks.

• Infinite loop when Selecting a panel?

  - by serhio

  I have a winform in witch I have a custom LongPanel with textboxes. In order to validate an eventually edited textbox when the user click somewhere out of textBoxY I use the following code: Private Sub LongPanel_MouseClick(ByVal sender As Object, _ ByVal e As MouseEventArgs) _ Handles MyBase.MouseClick _AttachedPanel.Select() End Sub In runtime application freezes at the "Select" line... I receive infinite panel Leave events(sender is a panel)... any idea why? EDIT: precision on panels parents: Form => SplitPanel => _AttachedPanel | _LongPanel (_LongPanel contains a reference to _AttachedPanel)

• Format TimeSpan in DataGridView column

  - by Dan Neely

  I've seen these questions but both involve methods that aren't available in the CellStyle Format value. I only want to show the hours and minutes portion (16:05); not the seconds as well (16:05:13). I tried forcing the seconds value to zero but still got something like 16:05:00. Short of using a kludge like providing a string or a DateTime (and only showing the hour/minutes part) is there any way I can get the formatting to do what I want.
