Make Non-TextBoxes Appear ReadOnly?
Mar 23, 2011Is there any way of making controls that aren't textboxes into readonly controls? Specifically I have a date time picker (but I have the problem occasionally with other controls), that I want to make ReadOnly as opposed to disabled so that the user can see clearly what is in the control but cannot edit it. Making a control like this disabled makes it hard to read and furthermore, gives the impression to the user that they are to ignore the field, which defeats the object.
I'm sure a suggestion will also be to stick the information into a text box, however there are other date time picker controls that CAN be edited in the same window, and it would make life a lot easier if the layout of each was exactly the same.

Programmatically Determine Background Of Image (logos, Etc) And Make Transparent?
May 20, 2011I'm attempting to write a solution so that my user's can "watermark" their Images with their Company Logo. I've got the actual watermarking part done and working so now I'm creating the "upload logo" feature so that they can provide me with the Logo they wish to appear watermarked onto their Images.I'm using VB.NET and this will probably end up in a Web Service that accepts the Logo JPG file, and returns the "altered" Logo. What I need to happen in this Web Service is:
1) Gray-scale the image. Which I have working as well, thanks to this article.
2) Make the background transparent (so the logo looks clean when watermarked onto an image). This is where I'm stuck.
I think for the most part, any logos that are uploaded will have a generic white background but I can't assume that. Is there a way to somehow detect the background of an image or the background colors, so that I may make those colors transparent?So basically what I need is just a way to determine the background on an Image or even just the background colors so that I may make them transparent.
Programmatically Change Foreground Color And Make Bold Text In Individual Cell Location On DataGridView Control?
May 5, 2010How to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.

Programmatically Creating A XLM File
May 25, 2009I have a project working on at work, it involves creating an invoice for each client and attaching that invoice to an email and sending it out. I chose to use XML for the data manipulations. I could have easily gone with a access file or a sqlCe db, but that would cause my data to be in a proprietary format; this is what i am running from. Furthermore, I have no experience with XML data and i thought here would be a good place to start.
I am reading the data for the invoices from a text file that will always be in a specific format each time it is produce. Information from this text file is stored in a generic list of a Class name Invoice.
The area where i am having the problem is where after collecting the data i now need to save it in an XML format. here is what i have so for

you see where i have function "writeNewInvoiceData" this is where i am stucked. I just don't know how to create this XML file.

Programmatically Create An .eml File That Contains A .pdf As Attachment?
Jun 12, 2009I'm writing my program in VB.Net,Part of my program is supposed to create a .eml file containing either an xml or a pdf file or both as attachments. Prior to writing this program, I had never seen what a .eml file looks like, let alone an .eml file with attachments(I never used any of the outlooks), so I got someone to send me an email containing both these attachments and save the .eml file, so I could use this as a template in my own program.However, I noticed that the pdf file, after having been attached, is a huge string of letters(see below). Probably some sort of encoding. My problem is, my program is going to be creating several different pdf files and adding them as attachments to .eml files. How do I encode the different pdf files into a similar huge string of text as the one below? Or am I going about this the wrong way? What would be an alternative way to do this? Because having to encode that long string of text seems like it would be a very daunting task.[code]
View 6 RepliesSave An Excel File Programmatically?
Oct 9, 2008I'm trying to import data from an Excel file into SQL server. However, the Excel file's format is not recognized by SQL Server. In fact, when I open it and try to save it, I get the following message:<filename> cannot be saved in the current format. To save your changes, click OK, then save it as the latest format.When I do that manually, it puts it in a usable format. However, the automated process I'm trying to build can't save it without intervention. When the VB in my SSIS process gets to it it brings up a save window, and I have to click the "Save" button and then the "Yes" button to replace the existing file. I'd strongly prefer to have this automated. I've have tried using the SendKeys.Send("{ENTER}") code, but it brings up this message:SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.I've tried SendWait, but it just seems to hang. I don't know how to change the application to handle error messages. I have also tried saving the Excel file as a new file with my VB code. However, as a new xls, xlsx, and csv file it still wasn't recognized by the import. I've only had success when manually saving it. In the SaveAs code I have been using, I'm only using the FileName parameter. I can't get any FileFormats to work or be recognized. Note, though, I'm opening the app and worksheet as Object variables. I can't add the Excel component in the Add Refrence area because only the .NET tab is there. I don't have a COM tab. I haven't asked if/how to get access to it, though.
View 3 RepliesC# - Programmatically Change The Sheet Name Of A Excel File?
Feb 2, 2012Whats the easiest way to change a sheet name of a newly create .xls file using VB.net.
The .xls is created as follows in a directory location:
filename = strDirectoryName & "1-TestFeedFile-" & strToday & "-" & iFile.ToString() & "of" & totalFile.ToString() & ".xls"
outputWriter = File.CreateText(filename)
The header of the xls file is created as follows:
line = "Blah1" & Chr(9) & "Blah2" & Chr(9) & "Blah3" & Chr(9)
outputWriter.WriteLine(line)
This code was orginally written to create a .txt file but was changed to a create a .xls, in that case I'm wondering if i'll have to change the code to create an new excel object which then can be used and access its sheet property?I don't mind if the solution is in VB.net or C#

How To Programmatically Change File Description Album Name
Aug 23, 2010I know album name is usually to music files & stuff probably but I guess album is what I need to categorize my video files correctly in Windows Media Player as it does organize my music files correctly when using album name & title. Anyways, these files I just want to change album name at the least & the description is something else I'd like to change on them as well. These files when I right click & go to properties then over to the details tab will show all the things like it usually does, but it will not let me change them. I am guessing this has to do because they are protected type files but I just want to change some things so they display correctly in Windows Media Player.
It already lets me change attributes inside Windows Media Player & at the bottom pane of the screen in explorer when the file is selected of attributes the file already had, but it won't let me add in the album name & description since it didn't start with one. I don't want to get rid of the protection on the files to be able to add these attributes either as I thought that was illegal or something, plus I don't want to download another program I don't have just to do this, whether it be a protection remover (which I said above, I think is illegal, even if it wasn't or isn't, I still wouldn't want to do that anyways) or even a thing that can change the attributes for me I wouldn't want to download since I just don't like downloading things that I won't use often, even if it's easy to remove & everything.
Since I already have VIsual Basic 2010 Express Edition installed I would just like to code something to change these attributes programmatically. It can be a simple textbox which is the location of the file and a button which changes the album name and description to "Just Text" that way I can put in each file I want to change & then click a button and it will be good from there. I will be able to change the variables after they are there to what I want after that from explorer or windows media player so I don't care for having textbox to change album name & description per file as I can just do this in explorer afterwords to what I want. By the way, files are in .wmv file format.
