View 2 RepliesAsp.net - Get Several Different "displays" In A Single Page, Rather Than Separate Different Views In Their Own Page?
Jul 3, 2009When and why would it be a good choice to keep the view of two different sets of information on the same page, and just change what's visible depending on different parameters?For example, an application I'm working on has three levels of users: Admin, Director and Project Manager. We have a Managers.aspx page which follows this flow of control:
If user is admin, load gridview list of directors with several simple CRUD-like properties. This includes a link for each director that, when clicked, will load a new gridview with several properties of all of the Project Managers belonging to the selected director.If user is director, load straight to the list of Project Managers that belong to this director, in the exact fashion as described in the second half of the "if user is admin" clause".This is all done on one Managers.aspx page. Why? What advantage does this hold? When else might this type of situation arise? Personally, this seems like a job for two separate pages. One listing the directors, and another listing the Project Managers.

View 3 RepliesAsp.net - Using Javascript On An Aspx Page That Uses A Master Page - Which Contains The Page In A Form?
Aug 7, 2009I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

May 11, 2011The thing is i have a Master page and a Content Page. I have a LoadComplete in Content Page and a PreRender in Master Page. The problem is one of my htmlcontrols on content page i change on the LoadComplete event server side of the content page. I also have some code for disabling controls on the Master Page PreRender event. For some reason all controls on the aspx side go through the Master Page prerender except the ones that i change on the LoadComplete side. How can i make sure the entire content page loads and then the Master Page PreRender event is called, making all the controls go through that event.

Getting Multi-page Output To Printer?
Aug 3, 2010I am continuing a previous thread to keep it from becoming tooooooo long. I tried most of the helpful suggestions offered by kind forum contributors but can't seem to make them work. I tried to analyze somewhat but it's beyond my skill level. So a different approach was to try to incorporate the code in the PrintDocument1_PrintPage event of my application that prints acceptably, but only prints first page of multi page document. I had three somewhat different approaches offered by John Anthony Oliver, ACAMAR, and Crazy Pennie. I cut the code and placed in the PrintDocument1_PrintPage event code. All three approaches made the "Printing"message box page counter go wild without outputing to my printer. Family Man Mike suggested resetting the variables after the e.HasMorePages=false line. I tried that approach but couldn't make that work for me, I really don't comprehend but made an attempt such as num_of_pages = 0, startVal = 0, endVal = 0. That had no affect on the functionality.

View 9 RepliesStream (and Convert?) Multi-page TIFF?
Aug 10, 2009I have built a simple image viewer in .NET and have the requirement to display multi-frame TIFF images in the browser. Presently, I have a (ashx) handler setup to stream back JPEGs that are co-mingled in the same database as the multi-frame TIFF's and it's worth mentioning that this handler will also return the first frame of the TIFF file in its current state. In the VB.NET code below (part of the handler) I am able to identify if a TIFF file has multiple frames and I started attempting to stitch the frames together but have not had any success yet. Has anyone returned multi-frame TIFF's using a similar approach? Note: I used the How to open a multi-frame TIFF image as a reference when developing the code below.

C# - Separating Multi-Page Tiffs Into Separate Pages?
Jan 20, 2012Currently I am using .NET to break apart multi-page tiffs into separate jpeg/pngs. The process on its own is perfectly fine. But after few weeks, I notice one big flaw in the page sizes. Each page I separate is the same (width/height NOT FILE SIZE) as the whole TIFF document combined. When the TIFF is displayed,this creates a massive black spot on the right/bottom of the image. This is a very big flaw as I can't determine the physical dimensions of each page as I am separating them. If I know ahead of time, I can at least write up some kind of cropping mechanism.

Writing A Single-page Tiff File
Oct 27, 2011We are using vb.net to write tiff images. After the image is first scanned into the system, we read it into bitmap memory, then we write it back out as a tif and pass in arguments that tell it what to put in the header. When we look at the original file, the header shows the "Subfile type" as "single page of multi-page image". But we noticed that after the file is written, the header now shows the "subfile type" as "Full-resolution image". We do not currently pass any argument in that tells it to do that.Is there a way to pass an argument into the function that writes the tiff file to tell it we want a single-page tiff and NOT a full resolution image? For some reason, our customer's tiff reader is not accurately reading some of these files and we believe it might be the cause of this.
