Background Image Will Not Switch Back From The Plain Background Color Of "control"?

Feb 19, 2011

what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:

Public Class Settings
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
MiDNiGHT.BackgroundImage = Nothing[code].......

Report Viewer Control Too Slow When Background Image Is Used?

May 25, 2009

I have already posted this question on the "reporting services" forum and received no responses, so i thought i'd give it a try here.

SQL server 2005 SP3, VS 2005, vb.net, RV control.

When i add a background image to the page header, body and page footer, The rendering takes about one second per page. Without the background images, it renders about 25-50 pages per second. My report is a statement print report and has about 1500 pages.

Since it is the same image on each page, why does the server need to send that image over and over again to the report viewer control?

In vb.net i have the Report Viewer control and i bring up a report in normal viewing mode. when i click on the print layout mode, or have that mode set up to be the default mode, It takes forever when i have a background image and virtually no time for the same report without the images. The images are gifs about 5 or 6k each. I have chosen to embed the image into the report.

How do i optimize the usage of background images so they do not interfere with the rendering speed? Or at least minimalize the slowdown.

[EDIT:] I have discovered that if i render it to PDF and open the PDF and page through the report, it is much much faster. In other words if i choose to render to 'printlayout', it is say 25 times slower than when i render it to default, and about 20 times slower then if i render it to PDF. And the PDF contains exact rendering for all pages, exactly the same rendering as the print layout mode generates.

[2008] Get Part Of Background Image Covered By ListView Control?

Mar 10, 2008

In my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.

Choose The 'blank' Value, It Will Not Let Me Past That Field

Aug 7, 2009

I have a combo box defined as a drop down list for a numeric field and have possible values under items. One of the values I have is a blank value (at the top of the items list) in case the user needs to leave the value as null. However, when I choose the 'blank' value, it will not let me past that field. I tried changing the 'data source update mode' to 'Never' and it let me past the field but then of course it won't save ANY of the values I choose.Is there any easy way around this without having to change the field to a string? I have several like this.

Calculator Program - Blank Field Shows Error

Mar 8, 2011

I'm doing a simple calculator program calculating Pennies, Nickels, Dimes and Quarters. I made a Try-Catch statement so that if the user enters letters into the text boxes, they get an error message. However, if the user leaves one field blank, the error message still pops up. What's the code so that I can get Visual Basic to recognize that an empty field is the same as 0 so that that message doesn't pop up? [Code]. What do I need to add to it to get that Error Message to stop showing when the user doesn't enter a value into one of the text boxes?

ErrorProvider Not Allowing Blank Date TextBox Field

Dec 31, 2009

I'm using the ErrorProvider in VB.Net (2005) which is associated with a BindingSource that is bound to a custom object that I have created. This custom object contains a date field that has a "Date" data type that. I am using a "TextBox" to bind the date field in my form. My issue is, whenever the TextBox loses focus and is blank, "String not recognized as a valid DateTime" is displayed by the ErrorProvider and the focus can't be changed to any other control on the Form. It's good that the ErrorProvider validates entries on Date fields by default (I didn't set up my custom object to display this particular error for the date), but it should allow blank values. I want the user to be able to have a blank date with no error message displayed. How can this be done using a Date field bound to a TextBox?

How To Make Program To Accept Blank Date Field

May 30, 2010

I have a field called PODate & TextBox txtPODate.text. It saves/updates fine when the txtPODate is filled. But when the txtPODate is blank, it throws an error. The problem is that I can't enter date for each record unless I got Purchase requisition converted into Purchase Order. Once it is converted to PO, I need to enter the date to update that filed. So, how can I make my program to accept blank date field.

Sep 12, 2009

I have a date field bound to a textbox. If I make any changes to the textbox, I get "stuck" in the field unless I put a valid date value. All I want to do is set the date textbox to blank and move on to the next field, but I can't. I am eternally "stuck" in the field unless I put a valid date value.

I did several hours of research, but looks like there is really no solution to this problem... Is this true?

Transparent Controls Over Form With Background Image Shows Backcolor Not Image?

Sep 18, 2009

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

Create A Blank Image In A Picturebox?

Oct 18, 2010

I'm using this snippet to create a blank image in a picturebox, but is it possible to have the image coloured so that I can see it. (I'll need to colour it later anyway).

.Image = New Bitmap(newPictureBox.Width, newPictureBox.Height) 'blank image.

Also if it is possible, I intend to draw lines, rectangles on the image (hopefully) and save the lot, so would I lose the colour, or would it get saved, or does it depend on what it gets saved as?

C# - Graphics.CopyFromScreen Creating Blank Image

Sep 19, 2011

I am using VB.NET to try and capture a portion of the screen so I found this code in several places to capture the whole screen:

Dim screenSize = SystemInformation.PrimaryMonitorSize
Dim bitmap = New Bitmap(screenSize.Width, screenSize.Height)
Using g As Graphics = Graphics.FromImage(bitmap)
g.CopyFromScreen(New Point(0, 0), New Point(0, 0), screenSize)
End Using
bitmap.Save("c:scratchscreenshot.png", System.Drawing.Imaging.ImageFormat.Png)

This works with no error throw and the file is created successfully but the resulting image is completely transparent (it is the correct size) - This question relates to the same error but the solution is to use Win32 GDI which I want to avoid if possible

Removing Blank Row In DataGrid Control

Is there a possiblity by any chance that a blank row in datagrid will be remove? Let's say the datagrid has this kind of info :

Column 1 | Column 2 | Column 3
User 1 NY 290-5542
Null Null Null
User 2 CA 350-5555

Lets assume that row 2 has a data and I inputed the data in row 3, however I change my mind I deleted the data in row 2 and that will leave row 2 blank. Is there a method where I can remove the row 2. The first thing come up on my mind was use a timer wherein it runs all the time.

RDLC Report Viewer Control Is Blank At Runtime?

Can't get the report viewer to do anything at runtime.After watching the tutorial on MSDN, it seemed simple.But I can't reproduce it. The data configuration is straightforward and no errors occur. Dropped back to putting something static on the designer like lines, backcolor and textboxes. They disappear too. The runtime control is active, just blank
